SecurityTracker Alert ID:  1010284
SecurityTracker URL:  http://securitytracker.com/id/1010284
CVE Reference:   CVE-2003-0965   (Links to External Site)
Date:  May 25 2004
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information

Description:   An input validation vulnerability was reported in Mailman. A remote user can conduct cross-site scripting attacks.

In December 2003, it was reported it was reported that the admin pages permit cross-site scripting attacks. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Mailman software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Mailman software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Solution:   Conectiva has released a fix.

DESCRIPTION
 Mailman[1] is a mailing list manager.
 
 This update fixes the following vulnerabilities for Conectiva Linux
 9:
 
 1) Cross site scripting vulnerability in the admin CGI script
 (CAN-2003-0965)[2]
 
 2) Cross site scripting vulnerability in the create CGI script
 (CAN-2003-0992)[3]
 
 3) Remote password retrieval vulnerability (CAN-2004-0412)[4]
 As mentioned in the 2.1.5 release announcement[5], previous mailman
 versions are vulnerable to a password retrieval attack which would
 give the attacker the password an user choose when he/she subscribed
 to a mailing list.
 
 For Conectiva Linux 8, the following vulnerability has been fixed:
 
 - CAN-2003-0991[6]: denial of service vulnerability caused by
 specific mail messages which would crash mailman.


SOLUTION
 It is recommended that all mailman users upgrade their packages.
