Description :

X-News is a news management system, written in PHP.  X-News uses a
flat-file database to store information.  It will run on most Unix and
Linux variants, as well as Microsoft Windows operating systems. 

X-News stores user ids and passwords, as MD5 hashes, in a world-
readable file, 'db/users.txt'.  This is the same information that is
issued by X-News in cookie-based authentication credentials.  An
attacker may incorporate this information into cookies and then submit
them to gain unauthorized access to the X-News administrative account.";

tag_solution = "Deny access to the files in the 'db' directory through the webserver.";
