Audrey Capital Employee Samuel “Otto” Woods Closed Discussion About WordPress Not Promoting Automattic’s Jetpack Plugin

Last week Automattic, the company from the head of WordPress Matt Mullenweg, announced they were going to contribute less to WordPress. In doing that, they complained that “we’ve observed an imbalance in how contributions to WordPress are distributed across the ecosystem, and it’s time to address this.” The credited author of the post is the Executive Director of WordPress.org. What was left unsaid was how Automattic benefits from WordPress over other companies because of its level of control over the project. We just ran into an instance where an attempt to address that wasn’t allowed predating the current situation with WordPress.

Last week, we wrote about how an Automattic employee who had access to non-public data on what top search terms for the WordPress Plugin Directory and their admission to changing the search algorithm for that to promote Automatic’s Jetpack plugin. That isn’t the only way that Jetpack is promoted in the WordPress Plugin Directory. From the admin interface of WordPress, going to the page to add a new plugin brings up a set of Featured plugins: [Read more]

Automattic Employee Changed WordPress Plugin Directory Search Algorithm to Promote Automattic’s Jetpack Plugin

As part of working on our Plugin Security Scorecard last year, we spent a fair amount of time using the search functionality of the WordPress Plugin Directory. Through that, we again and again ran across search results that prominently featured plugins with high install counts that were not relevant to the search results, while relevant plugins were sometimes buried later in the results.

One of the examples were you can see that happening is on a search for “translation”, which has as its fourth result, a 3+ million install backup plugin: [Read more]

WordPress Coding Standards is Failing to Warn About Missing Sanitization and Requiring Unnecessary Sanitization

One of the things that our new Plugin Security Scorecard uses to grade the security of WordPress plugins is a subset of the checks from our Plugin Security Checker. The subset is intended to be things that are always a security issue, which should be addressed. While the full set of checks will flag things that could be secure, but often are not secure and need to be checked. That subset involves checking for things you would expect to be issues with certain types of plugins and from certain developers. But the actual results of plugins checked so far tell a different story.

The 5+ million install plugin Wordfence Security has been found to be using “[t]he function filter_input() is used without a filter, so it doesn’t do any filtering.” Similarly, the 100,000+ install Jetpack Protect plugin is found to be using “[t]he function filter_var() is used without a filter, so it doesn’t do any filtering.” That plugin is from Automattic, the company so closely associated with WordPress that it now is not uncommon for WordPress to be seen as an arm of the company. That isn’t the only plugin from Automattic with issues. With the 4+ million install Jetpack and 7+ million install WooCommerce have been found to have both the previously mentioned issues. The threat posed by that would depend on what is done after the filter-less filtering is done, but the filter-less filtering shouldn’t be happening even if there isn’t a larger issue. [Read more]

Five WordPress Security Plugins Prevented Exploitation of Serious Vulnerability in Another Security Plugin

One of the things that should have long ago raised a lot of alarm about the state of the WordPress security industry is how often security plugins are found to contain vulnerabilities. Instead, it has been treated as evidence that it is normal for plugins to be insecure, not that there is something very wrong with security providers. That is quite unfortunate because it means that the good providers are not getting the support they deserve and security is suffering for it.

In June 2022, we did a large-scale test to see if WordPress security plugins would have stopped a vulnerability of a type, persistent cross-site scripting (XSS), that hackers are known to widely exploit, which was found in the security plugin WP Cerber Security. The results were not good. Only two of 31 plugins provided protection against the vulnerability itself. Last year, another vulnerability of that type was disclosed in the plugin. So we were curious to see how many plugins protected against that one. [Read more]

How a WordPress Firewall Plugin Stops Exploitation of Zero-Day That Automattic’s Jetpack Didn’t

When it comes to protecting WordPress websites from being hacked through vulnerabilities in plugins, the solution is often simply keeping plugins up to date. But that doesn’t work when a hacker finds a vulnerability and starts exploiting it, otherwise known as a zero-day, as there is no update available. That is where an additional security plugin or service can possibly provide protection. But do they? The answer is often that they won’t. Making that more problematic is that often the marketing of the solutions would tell you otherwise.

Recently, we looked at one example of how firewall plugins could easily detect and stop exploit attempts for a widely exploited vulnerability, but most didn’t. Let’s look at another example of how a firewall plugin can provide protection. This time with a zero-day. We will touch on a couple of examples of why web application firewalls (WAFs) such as a cloud based security service are unable to handle things as well. [Read more]

NinjaFirewall and Plugin Vulnerabilities Firewall Are Only WordPress Security Plugins That Protected Against Recent Zero Day

Among the common, but inaccurate, security advice you will hear is that WordPress won’t get hacked if you take basic security measures, including keeping plugins up to date. While doing the basics is really important, the reality is that keeping plugins up to date does nothing to stop a zero-day, a vulnerability being exploited before the developer is aware of it. That is an area where a security plugin could provide additional protection. But just because they could, it doesn’t mean they will. More problematically, WordPress security plugin developers have for years claimed to provide zero-day protection when they don’t. The solution is to do testing to see which plugins really provide protection against zero-days.

Recently, a zero-day role change vulnerability in the 200,000+ install WordPress plugin Ultimate Member was spotted being exploited by the web host Tiger Technologies. That vulnerability was being exploited to create a new WordPress user and then change the user’s role to Administrator, which gives them full access to the website. [Read more]

Our Firewall Plugin Caught That Jetpack’s “Internal Audit” of Slimstat Analytics Missed That Vulnerability Still Exists

Recently Automattic’s Jetpack claimed to have done an “internal audit” of the WordPress plugin Slimstat Analytics and found an authenticated SQL injection vulnerability that was subsequently fixed. We don’t know what an internal audit is supposed to be, but they failed to fully test or check over the vulnerable code and the authenticated SQL injection vulnerability still exists (which isn’t that surprising, considering the discoverer is a former employee of Sucuri). They also missed another security issue in the relevant code, which helped lead to the vulnerability still existing. Interestingly, an in development feature of our firewall plugin caught that the issue hadn’t been fully resolved.

Another Automattic unit, WPScan, also missed that this wasn’t fully resolved: [Read more]

Only 25% of WordPress Security Plugins Protected Against Widely Exploited Plugin Vulnerability

In late January, an unfixed vulnerability in a WordPress plugin with 40,000+ installs started to receive widespread exploitation attempts and many websites were hacked. The hacking was in part caused by multiple WordPress security providers, including Wordfence, WPScan, and Patchstack, who all claim to have teams of experts reviewing vulnerabilities in WordPress plugins, claiming that the vulnerability had been fixed three months before that. The moderators of the WordPress Support Forum made the situation worse by deleting an early indication of the problem in the form a message complaining about a website being hacked because of the plugin.

The developer of the plugin promptly fixed the vulnerability once we advised them that it still existed. They then went further than other plugin developers usually do when a plugin has had an exploited vulnerability and got a security review done to ensure the plugin was now properly secured.

Here Are the 4 WordPress Security Plugins That Protected Against a Vulnerability Wordfence Failed to Protect Against Despite Having Discovered It

Last week, Wordfence disclosed the details of an authenticated persistent cross-site scripting (XSS) vulnerability they had found in a popular WordPress plugin with 3+ million installs (as well as something else that wasn’t really a vulnerability). There were some things they said in their post that are rather problematic.

One of them was that they were claiming to have responsibly disclosed the vulnerability, while also contradicting that. According to their post, the day before they notified the developer of the plugin about the vulnerability, they were already selling access to information about exploiting the vulnerability through their Wordfence Premium service. That isn’t responsible disclosure and any hacker willing to pay for the service could have started exploiting this before the developer was even notified about it. Wordfence’s paying customers would have been protected from it at the time, but others would not without having some other security in place. [Read more]

WordPress Security Plugins Don’t Prevent Disclosure of One-Time Password Through Exploited Plugin Vulnerability

A month ago, we saw a hacker looking to exploit a vulnerability that had recently been fixed in the WordPress plugin User Verification. That vulnerability discovered by Lana Codes involved the plugin’s functionality to email a one-time password for logging in to WordPress. The problem with the functionality is that it didn’t just email the password, it also sent it back as part of the response from the request to have it emailed. So an attacker could submit the request to have that emailed for a WordPress user’s account, get the password that was only supposed to be emailed, and then log in to that account.

Trying to prevent an information disclosure issue like this would be difficult for a WordPress security plugin without being aware of the particular vulnerability, as it would have to realize that something that shouldn’t be disclosed is being disclosed, so it would be unlikely that a security plugin would provide protection. Our own firewall plugin, Plugin Vulnerabilities Firewall, doesn’t have protection against such a situation, but we are always looking to see how we might be able to expand its protection, so we were curious to see if any other plugins provided protection.
