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

High Nessus Network Monitor Plugin ID 6991


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


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.


Upgrade to ModSecurity version 2.7.3 or later.
