The remote web server contains a Python application that is affected by a log spoofing vulnerability.
The version of Mailman installed on the remote host fails to sanitize user-supplied input before writing it to the application's 'error' log. An unauthenticated remote attacker can leverage this flaw to spoof log messages. In addition, the application is reportedly affected by a denial of service issue involving headers that do not conform to RFC 2231 as well as several cross-site scripting vulnerabilities.
Upgrade to version 2.1.9rc1 or higher.
