ModSecurity < 2.5.9 Multipart Request Header Name DoS

high Nessus Plugin ID 67125

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 2.5.9. It is, therefore, potentially affected by a denial of service vulnerability. An error exists related to multipart form HTTP POST requests with a missing part header name that could allow an attacker to crash the application.

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 2.5.9 or later.
