The remote host is running post-nuke. It is possible to use it
to determine the full path to its installation on the server
or the name of the database used, by doing a request like :

/modules.php?op=modload&name=Members_List&file=index&letter=All&sortby=foobar

An attacker may use these flaws to gain a more intimate knowledge
of the remote host.

Solution : Change the members list privileges to admins only, or disable
the members list module completely
Risk factor : Low";
