ModSecurity < 2.7.3 XML External Entity (XXE) Data Parsing Arbitrary File Disclosure

high Nessus Plugin ID 67127

Language:

Synopsis

The remote web application firewall may be affected by a file disclosure vulnerability.

Description

According to its banner, the version of ModSecurity installed on the remote host is earlier than 2.7.3. It is, therefore, potentially affected by a file disclosure vulnerability. An improperly configured XML parser could allow untrusted XML entities from external sources to be accepted, thus leading to possible arbitrary file disclosure.

It could also be possible for internal network servers to receive unauthorized requests. Denial of service conditions are also possible.

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 2.7.3 or later.
