ModSecurity < 2.7.4 forceRequestBodyVariable Action Handling DoS

medium Nessus Plugin ID 67128

Language:

Synopsis

The remote web application firewall may be affected by a denial of service vulnerability.

Description

According to its banner, the version of ModSecurity installed on the remote host is earlier than 2.7.4. It is, therefore, potentially affected by a denial of service vulnerability. An error exists related to handling the action 'forceRequestBodyVariable' that could allow an HTTP request to cause a NULL pointer to be dereferenced and an application crash.

Note that Nessus has not tested for this issue but has instead relied only on the version in the server's banner.

Solution

Upgrade to ModSecurity version 2.7.4 or later.
