WordPress W3-Total-Cache 0.9.2.4 Username / Hash Extraction

The W3-Total-Cache Wordpress plugin versions 0.9.2.4 and below can cache database statements and its results in files for fast access. Version 0.9.2.4 has been fixed afterwards so it can be vulnerable. These cache files are in the webroot of the Wordpress installation and can be downloaded if the name is guessed. This Metasploit module tries to locate them with brute force in order to find usernames and password hashes in these files. W3 Total Cache must be configured with Database Cache enabled and Database Cache Method set to Disk to be vulnerable.
