TimThumb 'timthumb.php' < 2.8.14 WebShot 'src' Parameter Remote Command Execution

medium Nessus Plugin ID 76873

Synopsis

The remote web server hosts a PHP script that is affected by a remote command execution vulnerability.

Description

The TimThumb 'timthumb.php' script installed on the remote host is prior to version 2.8.14. It is, therefore, affected by a remote command execution vulnerability due to a failure to properly sanitize user-supplied input to the 'src' parameter. A remote, unauthenticated attacker can leverage this issue to execute arbitrary commands on the remote host. Note that the script is only affected when the 'WebShot' feature is enabled.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to version 2.8.14 or later.
