One of the reasons why security is in such bad shape despite the enormous amount of money spent on it is that there is a failed market when it comes to security products and services. In simple terms it isn’t currently possible for consumers to make well informed decisions between different products and services due to rampant falsehoods and outright lies about them as well as a lack of watchdogs to limit those or independent entities that provides accurate information needed to be able to make informed decisions. What sticks out to us is how widespread these falsehoods and outright lies are. We often see them in just the somewhat obscure area we deal in, data on vulnerabilities in WordPress plugins.
Just last week we discussed how the makers of the very popular WordPress security plugin, Wordfence Security, were lying by claiming that the data source they use is “official” and only contains “confirmed/validated” vulnerabilities. In reality neither of those claims is true, there is no official source of WordPress plugin vulnerability data and their data source doesn’t actually confirm or validate vulnerabilities before including them. What they didn’t mention nor are we aware of them disclosing elsewhere is what the data source used is, which is the WPScan Vulnerability Database. They are hardly alone in using that source and they are certainly not alone in not being upfront about using that data source, which is its own problem because we have seen people believe that multiple organizations were confirming a vulnerability when all of them were simply repeating an unconfirmed claim from that data source.
Even in an instance where a service was being upfront about using their data, they were falsely claiming that it providing better quality data than it truly does. Three months ago we discussed MainWP promoting their usage of WPScan’s data with the claim that:
The Vulnerability database updates itself real-time so you don’t miss out on any vulnerabilities.
The reality here is that something updating in real-time does not say anything about the completeness of its data, just how much time it takes for new data to propagate and WPScan’s data is far from the most complete.
The WPScan Vulnerability Database is Not Listing any Vulnerabilities in This Plugin
As we mentioned earlier today, yesterday we had a request probably from a hacker on this website for a file from the plugin Google Drive for WordPress (wp-google-drive), which contains a vulnerability that was disclosed a month ago. As we discussed at the time of disclosure, the vulnerability was incorrectly labeled as being a remote code execution (RCE) vulnerability when disclosed. The actual type of vulnerability, arbitrary file deletion vulnerability, is a type that based on past experience is not something that hackers have been very interested in, so the interest from a hacker may be due to them believing the plugin actually contains a RCE vulnerability, since those are much more likely to be exploited, at least based on past experience.
Whether something in the plugin is actually going to be exploited or not, it would seem that letting people know that this plugin has publicly disclosed unfixed vulnerability would be even more important considering there is what looks to be targeting of the plugin. If you are relying on WPScan’s data though you wouldn’t know about it. If they had any vulnerability for the plugin in their data set it should be listed between the following two plugins, but nothing is listed:
By comparison we have listed the vulnerability in our data set since April 13. Considering that the vulnerability is unfixed and was listed on a prominent general data source since shortly before that, there isn’t a good reason for WPScan’s data to not contain it. At the same time WPScan’s data is available for free for non-commercial software, so the quality may be in line with what should be expected in that instance. The problem though is that often times it is promoted like MainWP promotes it, leading people to believe they are getting access to data at the same quality level as ours, without the cost of ours.
Other Free Sources Do Better, But Still Get It Wrong
WPScan isn’t the only free accessible source of vulnerability data and others do better when it comes to this plugin.
With the companion plugin for this service we include free data on vulnerabilities that look to be being exploited. Due to noticing the request for this plugin we added the previously disclosed vulnerability to it today, along with another vulnerability we found while looking over things.
In looking at other free data sources we found they included the vulnerability, though inaccurately labeled.
The plugin WebDefender, which contains its own vulnerability data, added the vulnerability on April 16, but labeled it as “Remote CE”, which seems to indicate they didn’t actually check over the report before adding it. Two days later the data source ThreatPress added the vulnerability and also incorrectly labeled it as a “Remote Code Execution (RCE) vulnerability”. When vulnerabilities are not checked over this can lead to a number other issues, including incorrectly stating that a vulnerability has been fixed when it hasn’t, which is rather common occurrence.
The closest we found to an accurate labeling was in spreadsheet linked to from an April 16 blog post on WPCampus that labeled it as “Authenticated Arbitrary File deletion” vulnerability. We are not sure where the idea that it required being logged in to exploit it, but at least the general type is correct.
