Apache mod_wsgi < 3.5 Apache Process Privilege Escalation
Medium Nessus Plugin ID 76497
SynopsisThe remote web server module is affected by a privilege escalation vulnerability.
DescriptionAccording 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.
SolutionUpgrade to mod_wsgi 3.5 or later.
