RELEASE DATE:
2010-10-05
DESCRIPTION:
A vulnerability has been reported in the JomSocial component for
Joomla!, which can be exploited by malicious users to compromise a
vulnerable system.

The vulnerability is caused due to the application allowing the
upload of files with arbitrary extensions to a folder inside the
webroot. This can be exploited to execute arbitrary PHP code by
uploading a PHP file.

Successful exploitation of this vulnerability requires that direct
video uploads are enabled and may require that directory listings are
enabled to access the uploaded file.

The vulnerability is reported in version 1.8.8. Prior versions may
also be affected.

SOLUTION:
Reportedly, an update to version 1.8.9 fixes the vulnerability.
