WHERE:

SOFTWARE:
MyBB (formerly MyBulletinBoard) 1.x

DESCRIPTION:
HACKERS PAL has discovered a vulnerability in MyBB, which can be
exploited by malicious people to conduct cross-site scripting
attacks.
Input passed in the URL to various scripts isn't properly sanitised
before being returned to the user as part of the link for "advanced
details". This can be exploited to execute arbitrary HTML and script
code in a administrative user's browser session in context of an
affected site.
Example:
http://[host]/mybb/calendar.php?">[code]
Successful exploitation requires that the victim has logon as an
administrative user and uses a browser that has not URL-encoded the
request (e.g. Internet Explorer).
The vulnerability has been confirmed in version 1.0.4. Other versions
may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
