When A Security Vulnerability Is Only One of the Issues With a WordPress Security Plugin

We don’t think too highly of the security industry and we are often reminded of why that is, as was the case when we did a quick check of the plugin Sitesassure WP Malware Scanner. We had run across the plugin on the website of a company, 911websiterepair.com, which offers to clean up hacked websites, where it was listed as their plugin. The plugin didn’t mention anything about that website instead it was connected to another website and the look of that website didn’t exactly give us a good feeling about the potential quality of the plugin:

Our Plugin Security Checker Found a Reflected XSS Vulnerability in WordPress Plugin with 100,000+ Active Installs

In a reminder of the rather poor state of security of WordPress plugins and how our Plugin Security Checker tool (which is accessible through a WordPress plugin of its own) can help you to get a better idea if they are in need of additional security scrutiny when we ran the plugin WP Google Map Plugin through the tool to check to see if it would have spotted a recently fixed reflected cross-site scripting (XSS) vulnerability in the plugin we found that the plugin still contained another vulnerability of the same type (it also would have identified the possibility of the previous vulnerability if it had been checked).

In the file /core/class.initiate-core.php the function fc_geocoding() outputs the value of the variable $_POST, which contains any POST inputs sent with a request, without escaping that: [Read more]

When Will WordPress Finally Understand That Burying Heads in The Sand Doesn’t Improve Security?

When it comes to improving the security of WordPress plugins what continues to amaze us is the extent that people that should be part of the solution are instead part of the problem. We got a reminder of that not too long ago with a question on the wordpress.org Support Forum about a possible security issue in the plugin WP Booking.

On February 5 someone created a new topic in the support forum for the plugin with the following message: [Read more]

Reflected Cross-Site Scripting (XSS) Vulnerability in CF7 Invisible reCAPTCHA

In the monitoring we do to keep track of vulnerabilities in WordPress plugins for this service one thing we have noticed is that developers are not always providing full or consistent information on new version of plugins. For version 1.3.1 of the plugin CF7 Invisible reCAPTCHA the changelog entry is “Minor bug fix: Resolved the caching issue.”. The development log entry for that version indicates something different, “Security Update in Cf7 Invisible reCAPTCHA”. In looking over the new version to see if there was a vulnerability being fixed in that version what we saw was there was a significant amount of changes that were made, which seems out of line with the changelog entry description of the change being made.

Due to the amount of changes it makes it a bit hard to figure out if there was a vulnerability fixed and we didn’t find something in our look over it. But we did see a reflected cross-site scripting (XSS) vulnerability that was introduced in that version. [Read more]

SiteGround Caused 300,000+ of Their Customers Websites to be Insecure Due to Their Plugin SG Optimizer

When it comes to blame for the poor state of web security one of the parties that should get more blame than they seem to get are web hosts. Not only do they often poorly handle security themselves, but increasingly they have been partnering with really bad security companies, allowing those security companies to cause even more problems. SiteGround is one of those web hosts, with their partnership with Sucuri (which in turns is owned by another web host, GoDaddy, with a horrible security record of their own). Sucuri is a  company that among too many issues to go through, tries to scare people in to hiring them to do unneeded work, lacks a basic understanding of security, and causes their customers websites to remain insecure when they were easily fixed by people not claiming to have the level expertise that Sucuri claims to have.

Considering that SiteGround would have so low regard for their customers to partner with Sucuri, it probably isn’t all that surprising that they have also caused 300,000+ of their customers’ websites (according to wordpress.org) that use their plugin SG Optimizer, to be insecure due to really poor security handling in the plugin.
