Joomla EasyBook Component Script Insertion Vulnerability

SECUNIA ADVISORY ID:
SA38626

VERIFY ADVISORY:
http://secunia.com/advisories/38626/

DESCRIPTION:
Jeff Channell has discovered a vulnerability in the EasyBook
component for Joomla, which can be exploited by malicious people to
conduct script insertion attacks.

Input passed via the "Homepage" form field in index.php (when
"option" is set to "com_easybook", "controller" is set to "entry",
and "task" is set to "add") when creating an entry is not properly
sanitised before being used. 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
data is being viewed.

The vulnerability is confirmed in version 2.0 rc4. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
