authentication bypass issue." );

"The remote host is running TrueGalerie, an album management 
system written in PHP.

There is a flaw in the version of TrueGalerie that could 
allow an attacker to log in as the administrator without 
having to know the password, simply by requesting the URL :

Provided PHP's 'register_globals' setting is enabled, an 
attacker may use this flaw to gain administrative privileges
on this web server and modify its content." );
