FPD and Security bypass vulnerabilities in Exploit Scanner for WordPress

Hello 3APA3A!

These are Full path disclosure and Security bypass vulnerabilities in Exploit Scanner for WordPress. This is security plugin for detecting exploits and backdoors in WordPress. Which failed to identify my Backdoored Web Application (BWA) - a reference test of backdoor scanners (released in December).

Last week I've published article "Backdoor scanners testing among plugins for WordPress" (http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2013-May/008832.html). In which I described the results of the testing of multiple plugins-scanners for WordPress and described methods of bypassing all of these scanners. Exploit Scanner was the most bypassable scanner among tested plugins.

Affected products:

Exploit Scanner for WordPress 1.3.3 and previous versions. Tested in Exploit Scanner 0.95, 1.0.4 and 1.3.3.

Affected vendors:

Exploit Scanner

Details:

Full path disclosure (WASC-13):

http://site/wp-content/plugins/exploit-scanner/exploit-scanner.php

Security bypass (WASC-31):

This security bypass allows to inject php backdoor into web site (for executing OS commands), which will not be identified by the plugin.

All details about detecting BWA by different versions of the plugin and methods of their bypass are described in my article.
