CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 13 2002
Impact:   User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.3
Description:   An authentication vulnerability was reported in Geeklog. In the default configuration, a remote user with an account on the application can log in as another user.

It is reported that when permanent cookies are enabled (the default configuration), Geeklog creates and stores a user's UID in a cookie after successful authentication. The cookie is subsequently used by the server to authenticate a user. A remote user can modify the UID in their cookie to gain access to another user's account, including an administrator's account.

Impact:   A remote user with an account on the system can log in as any other user.
Solution:   The vendor has issued a fixed version (1.3.1), available at the Vendor URL.
