Mailman private.py Directory Traversal Vulnerability

Checks for Mailman private.py Directory Traversal Vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

Authenticated Mailman users can view arbitrary files on the remote
host.

Description :

According to its version number, the remote installation of Mailman
reportedly is prone to a directory traversal vulnerability in
'Cgi/private.py'. The flaw comes into play only on web servers that
don't strip extraneous slashes from URLs, such as Apache 1.3.x, and
permits a list subscriber, using a specially crafted web request, to
retrieve arbitrary files from the server - any file accessible by the
user under which the web server operates, including email addresses
and passwords of subscribers of any lists hosted on the server. For
example, if '$user' and '$pass' identify a subscriber of the list
'$listname@$target', then the following URL :

http://$target/mailman/private/$listname/.../....///mailman?username=$user&password=$pass

permits access to archives for the mailing list named 'mailman' for
which the user might not otherwise be entitled.
