Description: An input validation vulnerability was reported in Mailman in 'private.py'. A remote user can access arbitrary files on the target system.
The true_path() function does not properly validate user-supplied input. A remote user that is a member of a private mailman list can submit a specially crafted input value to access files on the system, including the mailman configuration files and passwords.
A demonsration exploit may contain the following string:
"/...../"
Marcus Meissner reported this flaw.
Impact: A remote user can access arbitrary files on the target system, including the mailman configuration files with user e-mail addresses and passwords.
Solution: Version 2.1.6 is not vulnerable.
For prior 2.1.x versions, the vendor has issued a patch, available at:
