IMPACT:
Cross Site Scripting
WHERE:
>From remote
SOFTWARE:
Plesk 7.x
http://secunia.com/product/3833/
DESCRIPTION:
Sourvivor has reported a vulnerability in Plesk, which can be
exploited by malicious people to conduct cross-site scripting
attacks.
Input passed to the "login_name" parameter in "login_up.php3" is not
sanitised before being returned to users. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of a vulnerable site by tricking a user into visiting a
malicious website or follow a specially crafted link.
Example:
http://[host]:8443/login_up.php3?login_name=">[code]
The vulnerability has been reported in versions 7.0.0 and 7.1.
Version 6.0 is reportedly not affected.
SOLUTION:
Edit the source to ensure that input is properly sanitised.
Filter malicious characters and character sequences in a proxy server
or firewall with URL filtering capabilities.
