Planet Zuda’s False Claim of a Cross-Site Request Forgery (CSRF) Vulnerability in Caldera Forms

If you have read either of our previous posts about the security company Planet Zuda you won’t be surprised to hear that they are selling a “fixed” version of another WordPress plugin where the vulnerability they claim to have fixed doesn’t exist. This time it is with the plugin Caldera Forms, which has 90,000+ active installs, and for which they want 29.99 for the “fixed” version.

In reading the first part of their post with the claim about this plugin it really seems that people behind this company are not all together with it, which makes deciphering what the vulnerability is supposed to be harder. Here is the main portion of the claim about the vulnerability: [Read more]

False Vulnerability Report: Cross Site Scripting Vulnerability in WP Job Manager

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them. The data on these false reports is also included in our service’s data.

Recently several security related changes were made to the plugin WP Job Manager, while reviewing the changes we didn’t see anything that looked like it would relate to something that would be classified as a vulnerability and needed to be detailed and added to our data set. The cause for one of the changes clarifies that there really wasn’t a vulnerability in that case. [Read more]

False Vulnerability Report: SQL Injection Vulnerability in Featured Image Resize

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them. The data on these false reports is also included in our service’s data.

Earlier today a thread was started on the WordPress Support Forum claiming that plugin Featured Image Resize contained a SQL injection vulnerability. Between us being notified of the thread and when went to check over things, half the message was removed. It isn’t clear if was removed by the poster or silently removed by a forum moderator (they do some strange stuff along those lines), whichever it was it causes a problem, as what was removed makes it easy to see that the vulnerability doesn’t exist.

False Vulnerability Report: Store XSS Vulnerability in WP Markdown Editor

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them. The data on these false reports is also included in our service’s data.

When it comes to false reports of vulnerabilities in WordPress plugins some of them don’t set off any red-flags until you start to look closely at them. Others, like a recent report claiming there was persistent cross-site scripting (XSS) in the plugin WP Markdown Editor set off multiple red-flags with the just a quick glance, though they still require being fully checked as some reports of actual vulnerabilities end up being quite of poor quality.

False Vulnerability Report: Cross Site Request Forgery / Cross Site Scripting in MailChimp for WordPress 4.0.7

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them. The data on these false reports is also included in our service’s data.

There seem to be a variety of causes for false reports of vulnerabilities in WordPress plugins, including lack of proper testing of possible vulnerabilities, intentional false reports, and what seems to be the cause of lot of them, the reporter not really understanding what the vulnerability would actually involve. No matter how obvious it is that they are false, these reports often get presented along side legitimate reports, that includes in WordPress security plugins, as we were just discussing when it comes to one plugin earlier today.

False Vulnerability Report: Cross Site Request Forgery / Cross Site Scripting in Newsletter 4.6.0

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them.

Yesterday a report of a cross-site request forgery (CSRF)/cross-site scripting (XSS) vulnerability in version 4.6.0 of the Newsletter plugin was released. The changelog noted a security fix in the version it was supposed to have been fixed in, but the wording seemed to downplay the claimed issue, as it said “Fixed a security issue on admin side only exploitable by logged in admins”. A cross-site request forgery vulnerability involves getting someone else to access a URL that causes them to send a request to their website, so if the vulnerability had existed, to say that it was only “exploitable by logged in admins” would have been true, but misleading, since it would not have required them to be trying to exploit the vulnerability. But as we quickly found, the misleading part was describing it as a security issue. [Read more]

False Vulnerability Report: WP Job Manager Arbitrary File Upload Vulnerability

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them.

Sometimes false reports of vulnerabilities are fairly easy to identify as likely being false without having to dig in to things, when the supposed proof of the vulnerability doesn’t match with what you should see with exploitation of a vulnerability. That was the case with a recent claim of an arbitrary file upload vulnerability in the WP Job Manager plugin. While an arbitrary file upload vulnerability allows any type of file to be uploaded, hence the name, hackers would normally use it to upload .php files. In this case those examples involved uploading .txt files. Also missing from the advisory was any information on the underlying code handling uploads, which if shown would have shown that the report was false. [Read more]

False Vulnerability Report: Self XSS Vulnerability in Yoast SEO 3.3.2

As part of our cataloging the vulnerabilities in WordPress plugins for our service we come across false reports of vulnerabilities from time to time. So that others don’t spend their time looking over these as well, we post our findings on them.

If you are going to promote your “web application security scanner” as being “False positive free” as Netsparker does, it would probably be a good not to release advisories for vulnerabilities that don’t actually exist, using data from that tool. But that is what Netsparker did with several recent advisories for WordPress plugins, including a claim of a self XSS vulnerability in Yoast SEO. [Read more]
