(Red Hat Issues Fix) Mailman Input Validation Hole in 'private.py' Discloses Files to Remote Users
SecurityTracker Alert ID:  1013146
SecurityTracker URL:  http://securitytracker.com/id/1013146
CVE Reference:   CVE-2005-0202   (Links to External Site)
Date:  Feb 10 2005
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.1 - 2.1.5
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:   Red Hat has released a fix.

3. Problem description:

The mailman package is software to help manage email discussion lists.

A flaw in the true_path function of Mailman was discovered.  A remote
attacker who is a member of a private mailman list could use a carefully
crafted URL and gain access to arbitrary files on the server.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0202 to this issue.

Note: Mailman installations running on Apache 2.0-based servers are not
vulnerable to this issue.

Users of mailman should update to these erratum packages that contain a
patch and are not vulnerable to this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date
