4) Description of Vulnerability

Secunia Research has discovered multiple vulnerabilities in Wuzly, 
which can be exploited by malicious people to conduct cross-site 
scripting attacks.

1) Input passed via the "Referer" header to admin/login.php and 
admin/404.php is not properly sanitised before being returned to the 
user. This can be exploited to execute arbitrary HTML and script code 
in a user's browser session in context of an affected site.

2) Input passed via various parameters to multiple scripts is not 
properly sanitised before being returned to the user. This can be 
exploited to execute arbitrary HTML and script code in a user's browser
session in context of an affected site.
