-\\Discussion
WordPress MU is prone to a cross-site scripting vulnerability because the application
fails to properly sanitize user-supplied input.
An attacker may leverage this issue to execute arbitrary script code in the browser of
an unsuspecting user in the context of the affected site. This may help the attacker steal
cookie-based authentication credentials and launch other attacks.
Versions prior to WordPress MU 2.7 are vulnerable.
-\\Exploit(s)/PoC(s):
An attacker can exploit this issue by enticing an unsuspecting user to follow a
malicious URI.
The following proof of concept is available:
curl -H "Cookie: my cookies here" -H "Host: <body
onload=alert(String.fromCharCode(88,83,83))>"
http://www.example.com/wp-admin/profile.php> tmp.html
$ firefox tmp.html
-\\Solution
The vendor has released WordPress MU 2.7 to address this issue. Please see the references
for more information.
