Closures of Very Popular WordPress Plugins, Week of April 19

While we already are far ahead of other companies in keeping up with vulnerabilities in WordPress plugins (amazingly that isn’t an exaggeration), in looking in to how we could get even better we noticed that in a recent instance were a vulnerability was exploited in a plugin, we probably could have warned our customers about the vulnerability even sooner if we had looked at the plugin when it was first closed on the Plugin Directory instead of when the vulnerability was fixed (though as far as we are aware the exploitation started after we had warned our customers of the fix). So we are now monitoring to see if any of the 1,000 most popular plugins are closed on the Plugin Directory and then seeing if it looks like that was due to a vulnerability.

Recently Closed Visual CSS Style Editor WordPress Plugin Contains Privilege Escalation Vulnerability That Leads to Option Update Vulnerability

When it comes to the security of WordPress plugins what other security companies generally do is to add protection against vulnerabilities after they have already been widely exploited, which obviously won’t produce great results since there is a good chance the websites using their service have already been hacked by the time they do that. One of the ways we keep ahead of that is to monitor the closure of the 1,000 most popular WordPress plugins in the Plugin Directory, since that closure can be due to a security issue and even if it is not, we have found the plugins being closed often contain security vulnerabilities, and as was the case with one less than two weeks ago, ones likely to be exploited. Hackers seem to be doing that type of monitoring as well. Through that we found that the plugin Visual CSS Style Editor, which has 30,000+ active installs and was closed yesterday, has two vulnerabilities that when combined lead to a type of vulnerability hackers would be likely to exploit.

Cross-Site Request Forgery (CSRF) Vulnerability in 404page

The plugin 404page was closed on the WordPress Plugin Directory on Saturday. As that is one of 1,000 most popular plugins our systems alerted us to its removal and then we checked things over to see if there was a security issue that might have led to it being removed. While no reason had been given for its removal, in a quick check we found a minor, but rather nasty vulnerability that could an attacker to cause WordPress users to disable their access to the website without intending it. We then used WPDirectory to see if other plugins might have similar code and found that a number of other plugins by the same developer do. Subsequently to us doing that, the vulnerability was fixed in 404page and then subsequently that was credited to Julio Potier, so it appears that was the cause of the closure, but the other plugins have not been fixed yet.
