DESCRIPTION:
A vulnerability has been discovered in the Recent Topics on Index
page plugin for MyBB, which can be exploited by malicious users to
conduct script insertion attacks.
Input passed via the "subject" parameter to newthread.php (when
"action" is set to "do_newthread") is not properly sanitised in
inc/plugins/recenttopicsindex.php before being displayed to the user.
This can be exploited to insert arbitrary HTML and script code, which
will be executed in a user's browser session in context of an
affected site when the malicious thread is being viewed.
The vulnerability is confirmed in version 1.0. Other versions may
also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
