Synopsis : 

The remote web server contains a PHP script that permits SQL injection
and cross-site scripting attacks. 

Description :

The remote version of Land Down Under is prone to various SQL
injection and cross-site scripting attacks provided PHP's
'magic_quotes' setting is disabled due to its failure to sanitize the
request URI before using it in 'system/functions.php' in the function
'ldu_log()'.  A malicious user may be able to exploit this issue to
manipulate SQL queries, steal authentication cookies, and the like. 

In addition, it also fails to properly sanitize the user-supplied
signature in forum posts..  A malicious user can exploit this
vulnerability to steal authentication cookies and manipulate the HTML
format in 'forums.php'.

Risk factor : 

Medium / CVSS Base Score : 4
