Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A vulnerability has been identified in PHP allowing malicious people to conduct Cross Site Scripting against sites using transparent SID support.

The problem is that input supplied to the "PHPSESSID" parameter isn't verified. This allows malicious people to create an URL like:

http://vulnerable_site/script.php?PHPSESSID="><some_evil_html_or_script>

This can only be exploited if "transparent SID support" is enabled.
