ModSecurity < 2.7.0 Multipart Request Parsing Filter Bypass

medium Nessus Plugin ID 67126

Language:

Synopsis

The remote web application firewall may be affected by a security bypass vulnerability.

Description

According to its banner, the version of ModSecurity installed on the remote host is earlier than 2.7.0. It is, therefore, potentially affected by a security bypass vulnerability. An error exists related to HTTP POST requests and 'Content-Disposition' headers containing extra lines that could allow a remote attacker to bypass certain filters and carry out attacks.

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 2.7.0 or later.
