Apache mod_wsgi < 3.5 Apache Process Privilege Escalation

high Nessus Plugin ID 76497

Language:

Synopsis

The remote web server module is affected by a privilege escalation vulnerability.

Description

According to the web server banner, the version of mod_wsgi running on the remote host is prior to version 3.5. It is, therefore, affected by a privilege escalation vulnerability.

The issue occurs due to the improper handling of error codes returned by 'setuid'. This flaw allows local attackers to manipulate the number of processes that are run by the user to affect the outcome of 'setuid' during the forking of daemon mode processes. This could allow the attacker to gain elevated privileges.

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

Solution

Upgrade to mod_wsgi 3.5 or later.
