LedForums Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA10113

VERIFY ADVISORY:
http://www.secunia.com/advisories/10113/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
From remote

SOFTWARE:
LedForums

DESCRIPTION:
Some vulnerabilities have been reported in LedForums, which can be
exploited by malicious users to conduct Cross-Site Scripting
attacks.

The vulnerabilities are caused due to missing validation of input
supplied to the "top_message" parameter in "index.php" and in topic
names. This can be exploited by including arbitrary HTML or script
code in the parameter or as a topic name, which will cause it to be
executed in a user's browser session when viewed.

Example:
http://[victim]/[path]/index.php?top_message=<script>alert(document.cookie)</script>

The vulnerabilities have been reported in LedForums Beta 1.

SOLUTION:
Filter malicious input in a HTTP proxy or firewall with URL filtering
capabilities.
