On April 6, 2023, the Wordfence Threat Intelligence team initiated the responsible disclosure process for two vulnerabilities in Getwid – Gutenberg Blocks, a plugin installed on over 50,000 WordPress sites. The plugin’s developers responded immediately, and we sent over the full disclosure the same day. A patched version of the plugin, 1.8.4, was released on April 13, 2023.
The most serious vulnerability had a high severity because it allows authenticated users to perform Server Side Request Forgery (SSRF), which can result in full access to the hosted instance on some cloud configurations. Additionally, it may allow further penetration into internal networks in some enterprise configurations. The other vulnerability is much lower in severity and allows authenticated users to clear and update the site’s template cache.
Wordfence Premium, Wordfence Care, and Wordfence Response customers received a firewall rule protecting against the Server Side Request Forgery (SSRF) on April 6, 2023. Wordfence Free users received the same protection on May 6, 2023.
The Getwid – Gutenberg Blocks plugin for WordPress is vulnerable to Server Side Request Forgery via the get_remote_content REST API endpoint in versions up to, and including, 1.8.3. This can allow authenticated attackers with subscriber-level permissions or above to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
The Getwid – Gutenberg Blocks plugin for WordPress is vulnerable to unauthorized modification of data due to an insufficient capability check on the get_remote_templates function in versions up to, and including, 1.8.3. This makes it possible for authenticated attackers with subscriber-level permissions or above to flush the remote template cache. Cached template information can also be accessed via this endpoint but these are not considered sensitive as they are publicly accessible from the developer’s site.
Technical Analysis
Getwid – Gutenberg Blocks is a plugin offering a library of pre-generated blocks which it makes available to plugin users and retrieves remotely from the developer’s server. Unfortunately, this remote retrieval functionality, which utilized the REST API, only required an authenticated user in vulnerable versions, meaning that even subscriber-level users could make use of it.
While the rest routes for both vulnerabilities used a capability check in the permissions_check function, the capability checked was read, which all users, even subscribers, are assigned.

On its own this was not a significant issue, but the get_remote_content function also failed to validate the URL passed in, meaning it could be used to retrieve information from any location via the server.

Only GET requests can be performed and the response data will only be rendered if it is JSON-formatted. However, sites hosted on Amazon AWS EC2 instances all have an endpoint which can be accessed internally and returns JSON-formatted credentials that can be used to access the instance.

The second issue was significantly less severe and made use of the minimal capability check on the ‘get_remote_templates’ function. While this would likely have minimal impact on a site, it still compromises the site’s integrity to some extent.
Disclosure Timeline
April 6, 2023 – The Wordfence Threat Intelligence team releases a firewall rule to Wordfence Premium, Wordfence Care, and Wordfence Response users and begins the responsible disclosure process. We send over the full disclosure to the developers. April 13, 2023 – The plugin developers release a patch in version 1.8.4 of Getwid. May 6, 2023 – Wordfence Free users receive the firewall rule.
Conclusion
In this blog post, we detailed a Server Side Request Forgery (SSRF) vulnerability in Getwid version 1.8.3 and earlier. This vulnerability allows authenticated attackers with subscriber-level permissions or higher to send arbitrary GET requests from the website, which can be used to obtain critically sensitive information in some configurations. We also described a lower-severity vulnerability allowing subscribers to clear the local template cache.
Wordfence Premium, Wordfence Care, and Wordfence Response users received a firewall rule to protect against any exploits targeting the SSRF vulnerability on April 6, 2023. Sites still using the free version of Wordfence received the same protection on May 6, 2023.
If you know someone who uses this plugin on their site, we recommend sharing this advisory with them to ensure their site remains secure, as the SSRF vulnerability poses a significant risk. If you or someone you know is hosted on AWS we also highly recommend migrating to IMDSv2 if you have not already, as it offers protection from not only this but the vast majority of SSRF vulnerabilities.
Alongside our usual work to discover, report, and remediate vulnerabilities in the WordPress ecosystem, the WordPress Threat Intelligence team has been conducting a deep-dive into WordPress plugin code with the objective of finding methods to bypass authentication and gain elevated privileges in WordPress plugins so we can help developers patch these vulnerabilities before threat actors can exploit them.
One such plugin we examined recently is Directorist, a popular tool used by over 10,000 WordPress sites to manage directory listings and classified ads.
On April 3, 2023, our team uncovered two significant vulnerabilities – an Arbitrary User Password Reset to Privilege Escalation, and an Insecure Direct Object Reference leading to Arbitrary Post Deletion. Both vulnerabilities were found to affect Directorist versions 7.5.4 and earlier.
Wordfence Premium, Wordfence Care, and Wordfence Response customers received a firewall rule to protect against any exploits targeting these vulnerabilities on April 4, 2023. Sites still using the free version of Wordfence received the same protection on May 4, 2023.
Unfortunately, on June 1, 2023, the plugin was closed due to developer unresponsiveness, and it currently remains unavailable for download from the repository. This presents an issue as site owners are unable to request an update directly via their WordPress dashboard. Given this situation, we advise site owners to either temporarily uninstall the plugin, or manually download the patched version, 7.5.5, and upload it to their sites for optimal protection. For this reason, we have intentionally kept specific vulnerability details to a minimum in this post.
Vulnerability Summaries from Wordfence Intelligence
Authenticated (Subscriber+) Arbitrary User Password Reset to Privilege Escalation
The Directorist plugin for WordPress is vulnerable to an arbitrary user password reset in versions up to, and including, 7.5.4. This is due to a lack of validation checks within login.php. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to reset the password of an arbitrary user and gain elevated (e.g., administrator) privileges.
Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary Post Deletion in listing_task
The Directorist plugin for WordPress is vulnerable to an Insecure Direct Object Reference in versions up to, and including, 7.5.4. This is due to improper validation and authorization checks within the listing_task function. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to delete arbitrary posts.
Technical Analysis
Password Reset Vulnerability
Directorist, created by wpWax, is designed to help businesses establish directory listings and classified ads on their WordPress sites. It includes a Login and Registration form that can be enabled using the [directorist_user_login] shortcode.
The Directorist Login and Registration form
This form features a “Recover Password” function, akin to the default WordPress “lost your password?” feature. In vulnerable versions, the underlying code lacks essential validation checks to ensure that the user attempting to reset a password is indeed the account owner. This could allow attackers with subscriber-level permissions or higher to reset the passwords of other users, including administrators, thereby gaining unauthorized elevated privileges and taking over the site.
Directorist “Recover Password” logic
Arbitrary Post Deletion Vulnerability
In addition, we found an arbitrary post deletion vulnerability in the plugin. Directorist listings are essentially custom WordPress posts. In vulnerable versions, the code designed to manage listing deletions lacks the necessary authorization checks to confirm the user is permitted to delete the listing and does not verify that the post being deleted is a Directorist listing. Consequently, this could enable threat actors with subscriber-level and above permissions to delete any post on a WordPress instance, including posts by administrators.

Disclosure Timeline
April 3, 2023 – The Wordfence Threat Intelligence team discovers and documents two vulnerabilities in Directorist. April 4, 2023 – The Wordfence Threat Intelligence team releases firewall rules to Wordfence Premium, Wordfence Care, and Wordfence Response users and begins the responsible disclosure process. May 4, 2023 – Wordfence Free users receive the firewall rules. June 1, 2023 – The plugin developers release a patch in version 7.5.5 of Directorist.
Conclusion
In this blog post, we reviewed two vulnerabilities in our ongoing vulnerability research focused on bypassing authentication and gaining elevated privileges – an Arbitrary User Password Reset to Privilege Escalation that allows threat actors to gain full control of a WordPress instance, and a less-severe Insecure Direct Object Reference to Arbitrary Post Deletion, both in Directorist versions 7.5.4 and prior.
The Wordfence Threat Intelligence team reported these vulnerabilities to the Directorist team on April 4, 2023, following responsible disclosure protocols. The Directorist team addressed these vulnerabilities and released the patch in Directorist version 7.5.5 on June 1, 2023.
We recommend all users update their Directorist plugin to the newest version available, which is 7.5.5 at the time of this writing, immediately to secure their websites.
Wordfence Premium, Wordfence Care, and Wordfence Response customers received a firewall rule to protect against any exploits targeting these vulnerabilities on April 4, 2023. Sites still using the free version of Wordfence received the same protection on May 4, 2023.

Key features of SMB firewalls
Firewalls designed for SMBs share many of the same characteristics as their enterprise-grade cousins—such as firewall rule and policy configuration, content filtering, reporting and analytics—while placing additional emphasis on affordability and ease of use.
Firewall rules and policies
Administrators should be able to set up firewall rules and policies that control traffic flow and block or permit traffic based on various criteria, such as source/destination IP addresses, ports, and protocols.
These rules and policies can be used to control the types of applications, services, and data that are allowed to traverse the network, as well as create restrictions on access.
Firewall rules and policies are essential to the security of a network, as they provide the first line of defense against malicious attacks.
Content filtering
Content filtering is the process of blocking or restricting certain types of content from entering or leaving a network. It can be used to block websites, applications, or data that may contain malicious or unwanted content, such as malware, viruses, or pornographic material.
Content filtering is typically implemented using a combination of hardware and software solutions. Hardware solutions, such as routers and switches, can be configured to block certain types of traffic or data or to restrict access to certain websites or applications. Software solutions, such as firewall rules and policies, can also be used to block or restrict certain types of content.
Reporting and analytics
Reporting and analytics are essential for any business network, as they provide important insights into the health and security of the network. Firewall reporting and analytics features allow network administrators to identify trends, detect potential threats, and analyze the performance of the network over time.
Reporting and analytics can also be used to identify any areas of the network that may be vulnerable to attack, as well as identify any areas where the network may not be performing optimally.
Affordability
For SMBs, affordability is a key factor when it comes to purchasing a firewall. SMB firewalls are typically more affordable than enterprise firewalls and can be purchased for as little as a few hundred dollars, so it is important to consider your budget when selecting a firewall.
Some SMB firewalls offer additional features for a fee, so consider what features are necessary for your network and the ones you can do without, as this will help you decide on the most cost-effective firewall solution. At the same time, be careful not to cut corners—your business’s data is too important to be insufficiently protected.
Ease of use and support
For SMBs, finding a firewall solution that is easy to use and has good support is essential. Firewalls should be easy to configure and manage so the network administrator can quickly and easily make changes as needed.
Additionally, good support should be available for any issues or questions that arise. This support should include an online knowledge base and access to technical support staff that can assist with any questions or problems, ideally 24/7.
How to choose the best SMB firewall software for your business
When shopping for the best SMB firewall software for your business, look for software that offers the features you need, easy installation and management, scalability to grow with your business, minimal impact on network performance, and an affordable price.
It’s also important to choose a vendor with a good reputation in the industry, backed up by positive reviews and customer feedback.

Frequently Asked Questions (FAQ)
Is an enterprise firewall different from a normal firewall?
Although they share many characteristics, an enterprise firewall is not the same as a consumer-grade firewall. Enterprise firewalls are designed to meet large organizations’ security needs and network infrastructure challenges. They are robust, scalable, and can handle high network traffic volumes and sophisticated threats, compared to generic firewalls for home or small office environments.
What is the strongest type of firewall?
A firewall’s strength depends on various factors, and no universally dependable firewall exists. A firewall’s effectiveness depends on its materials, configuration, and how well it fits into the organization’s security needs.
That said, next-generation firewalls (NGFWs) provide improved security capabilities and are often considered the ideal firewall solution in today’s enterprise. NGFWs combine traditional firewall features with additional functionality such as application awareness, intrusion prevention, deep packet monitoring, and user-based policies. They provide advanced protection against modern threats with greater visibility and control over network traffic.

Knowing your network’s vulnerabilities is just the beginning. Here are the best vulnerability management tools to keep your data locked up safe.
On May 20, 2023, our Wordfence Threat Intelligence team identified and began the responsible disclosure process for a Privilege Escalation vulnerability in WPDeveloper’s ReviewX plugin, which is actively installed on more than 10,000 WordPress websites. This vulnerability makes it possible for an authenticated attacker to grant themselves administrative privileges via a user meta update.
Wordfence Premium, Wordfence Care, and Wordfence Response users received a firewall rule to protect against any exploits targeting this vulnerability on May 22, 2023. Sites still using the free version of Wordfence will receive the same protection on June 21, 2023.
We contacted WPDeveloper on May 20, 2023, and received a response the next day. After providing full disclosure details, the developer released a patch on May 22, 2023. We would like to commend the WPDeveloper development team for their prompt response and timely patch, which was released in just one day.
We urge users to update their sites with the latest patched version of ReviewX, which is version 1.6.14 at the time of this writing, as soon as possible.
The ReviewX plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.6.13 due to insufficient restriction on the ‘rx_set_screen_options’ function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role via the ‘wp_screen_options[option]’ and ‘wp_screen_options[value]’ parameters during a screen option update.
Technical Analysis
ReviewX is a plugin that primarily enables customers to add ratings and reviews to WooCommerce stores, but it is also possible to use it with custom post types.
The reviews are listed on the WordPress admin page, which includes a screen option for how many reviews should be displayed per page for the admin user. Unfortunately, this feature was implemented insecurely, allowing all authenticated users to modify their capabilities, including granting themselves administrator capabilities.
Upon closer examination of the code, we see that the ‘rx_set_screen_options’ function, which updates a user’s per-page screen option, is hooked to the ‘admin_init’ action.
This hook is triggered on every admin page without any post type or page restrictions. This means that the ‘rx_set_screen_options’ hooked function is invoked on all admin pages, allowing users who otherwise do not have access to the plugin to also access the function, as the function itself does not contain any restrictions.
This makes it possible for any authenticated user with an account, such as a subscriber, to invoke the ‘rx_set_screen_options’ function.
The function includes a nonce check, but it uses a general nonce that is available on every admin page where there is a screen option.
The most significant problem and vulnerability is caused by the fact that there are no restrictions on the option, so the user’s metadata can be updated arbitrarily, and there is no sanitization on the option value, so any value can be set, including an array value, which is necessary for the capability meta option.
This made it possible for authenticated users, such as subscribers, to supply the ‘wp_capabilities’ array parameter with any desired capabilities, such as administrator, during a screen option update.
As with any Privilege Escalation vulnerability, this can be used for complete site compromise. Once an attacker has gained administrative user access to a WordPress site they can then manipulate anything on the targeted site as a normal administrator would. This includes the ability to upload plugin and theme files, which can be malicious zip files containing backdoors, and modifying posts and pages which can be leveraged to redirect site users to other malicious sites.
Disclosure Timeline
May 20, 2023 – Discovery of the Privilege Escalation vulnerability in ReviewX. May 20, 2023 – We initiate contact with the plugin vendor asking that they confirm the inbox for handling the discussion. May 21, 2023 – The vendor confirms the inbox for handling the discussion. May 21, 2023 – We send over the full disclosure details. The vendor acknowledges the report and begins working on a fix. May 22, 2023 – Wordfence Premium, Care, and Response users receive a firewall rule to provide protection against any exploits that may target this vulnerability. May 23, 2023 – A fully patched version of the plugin, 1.6.14, is released. June 21, 2023 – Wordfence Free users receive the same protection.
Conclusion
In this blog post, we detailed a Privilege Escalation vulnerability within the ReviewX plugin affecting versions 1.6.13 and earlier. This vulnerability allows authenticated threat actors with subscriber-level permissions or higher to elevate their privileges to that of a site administrator which could ultimately lead to complete site compromise. The vulnerability has been fully addressed in version 1.6.14 of the plugin.
We encourage WordPress users to verify that their sites are updated to the latest patched version of ReviewX.
Wordfence Premium, Wordfence Care, and Wordfence Response users received a firewall rule to protect against any exploits targeting this vulnerability on May 22, 2023. Sites still using the free version of Wordfence will receive the same protection on June 21, 2023.
If you know someone who uses this plugin on their site, we recommend sharing this advisory with them to ensure their site remains secure, as this vulnerability poses a significant risk.

The biggest release since 1.0, CrowdSec Engine 1.5 brings you new features, major enhancements, and more control of your security management. Discover all that is new in 1.5 and how to get started in this article.
We launched a private preview of the CrowdSec Engine 1.5 to our community members in March to allow them to test it out and give us feedback. After a few months of testing, it was clear that the CrowdSec Engine 1.5 was ready for its debut by the end of May. So here it is, new features, major enhancements and more ways to manage your security. Check out all the updates and what’s new below. You can also read about the increased performance and faster response times when processing high volumes of logs that our community members experienced with the CrowdSec Engine 1.5.
“We are delighted to announce the launch of CrowdSec Engine 1.5 today. Following our last release in February 2022, we have been busy listening to our users to deliver a new version with significant enhancements, including the ability to receive “orders” from the console. We have also developed several new features, including compliance and post-exploitation scenarios to the engine. We are also hugely grateful to the CrowdSec community that has been busy testing the release over the last few months to ensure a smooth and successful roll-out for all our users. ” – Thibault Koechlin, Chief Technology Officer, CrowdSec
Polling API Integration
With the polling API, the Console can now send orders to the CrowdSec instances. Allowing users to manage their decisions (banned IPs at a given time). Let’s dive into what that means.
Real-time decisions management
The new Polling API gives you the ability to complete real-time decision management within the console. For users with many instances, you can now ban IPs on all of your instances at once, all from the comfort of a single page, rather than running an automation script to update all instances. A great timesaver for SecOps teams.
Teaser: Secure and custom configure the fleet of instances from the Console
In the future, the polling API feature will allow users to set up parsers and scenarios directly from the CrowdSec Console.
New Blocklist API and Premium Blocklists
We recently announced the external IP blocklists which allow all of our users to subscribe to at least 2 (new) additional blocklists created by the CrowdSec team, in addition to our community fuelled blocklist to better protect your instances.
Viktoria Rei Bauer (@ToeiRei on Discord, Twitch, and Twitter), CrowdSec Ambassador, saw a 190% increase in blocked IP addresses after implementing CrowdSec’s new Blocklist API and subscribing to 2 new blocklists.
“My average number of IP blocks was 2,000 per day. The day isn’t even over and I’ve already blocked 6,000 IPs.”
The chart below shows the impact the blocklist subscription made to Rei’s CrowdSec pfSense deployment. The red line shows the implementation of the blocklists that resulted in a 183% increase of malicious IPs blocked, peaking at a 400% increase.
Kubernetes audit acquisition
The feature we presented at Kubehuddle UK 2022 is finally here:
Kubernetes Cluster Monitoring now gives our users the ability to monitor and protect their whole K8s cluster, and not just the services running on it.
S3 audit acquisition
CrowdSec now supports reading logs stored in S3 bucket, allowing you to process logs generated by AWS services (such as ALB access logs or Cloudfront logs).
Auditd support
Allows for the detection of “Post Exploitation Behaviors”, including:
base64 + interpreter (perl/bash/python)
curl/wget and exec
pkill execve bursts
rm execve bursts
exec from suspicious locations
CrowdSec CTI API helpers
You can now query CrowdSec’s Cyber Threat Intelligence (CTI) from your parsers and behavior scenario thanks to our new CTI API, allowing you to react to each threat differently according to each IPs reputation and classification.
This new CTI API allows CrowdSec and the CTI to be more interactive with each other, allowing users to query more information around a specific IP. For example, you can now query the machine’s usage, as well as the type of attack it relates to. CrowdSec is now able to query all this data in real-time, helping users to detect false positives, and also reducing alert fatigue.
AWS Cloudtrail Scenarios
Thanks to 1.5’s new behavior detection capabilities, we were able to create an advanced AWS Cloudtrail scenario helping you to detect and better understand what’s happening on your cloud. Below you can see a list of activities you are now able to detect.
Detect AWS CloudTrail configuration change
Detect AWS Config configuration change
Detect AWS console authentication failure
Detect AWS IAM policy change
Detect AWS KMS key deletion
Detect login without MFA to the AWS console
Detect AWS NACL change
Detect AWS Network Gateway change
Detect AWS root account usage
Detect AWS route table change
Detect AWS S3 bucket policy change
Detect AWS Security Group change
Detect AWS API unauthorized calls
Detect AWS VPC change
Feature flag support
This new feature allows us to have some features within the Security Engine that are disabled by default but can be activated manually by the user.
This will facilitate the inclusion of beta features safely and give more chances to the community to preview what’s coming and help us test the features in a range of use cases.
Detection Engine improvements
Conditional buckets: an improvement of our behavior detection system allows for more complex expression for the alert triggering mechanism
Event data stash: allows parsers to capture data for future enrichment. Adding the capability to detect advanced malicious behaviors
CAPI Whitelist
While the community blocklist is highly curated, and designed to avoid false positives, sometimes a shared IP used by both innocent and malicious actors will end up in it, so we’ve added the capability to create whitelists that can also be applied to the community-powered blocklist.
Conclusion
We would like to thank our community of users who have helped us reach this major milestone! Thanks to your feedback we have been able to create a release that truly caters to your needs and enhances your use of CrowdSec.
Interested in using CrowdSec Engine 1.5? If you haven’t already, install the CrowdSec Security Engine and then, sign-up for the CrowdSec Console. We will also be hosting a live webinar to go over all the new features and enhancements!
