Apache mod_wsgi < 4.2.4 Privilege Dropping Privilege Escalation

high Nessus Plugin ID 76498

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 4.2.4. It is, therefore, affected by a privilege escalation vulnerability.

The issue is triggered when attempting to drop group privileges and an error with 'setgid', 'setgroups', and 'initgroups' occurs. The error is reported, but mod_wsgi continues to run with root group privileges, rather than dropping privileges as intended. A local attacker could potentially gain escalated 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 4.2.4 or later, or apply the patch.
