Synopsis

vBulletin < 5.6.7 Patch Level 1 / < 5.6.8 Patch Level 1 / < 5.6.9 Patch Level 1 Remote Code Execution

Description

According to the self-reported version in its response header, the version of vBulletin hosted on the remote web server is < 5.6.7 Patch Level 1, < 5.6.8 Patch Level 1 or < 5.6.9 Patch Level 1. It is, therefore, affected by a Remote Code Execution via user[searchprefs] parameter within ajax/api/user/save endpoint.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to vBulletin version 5.6.9 Patch Level 1 or later.
