Subject: [TYPO3-announce] TYPO3 Security Bulletin TYPO3-20080527-1: Cross Site Scripting vulnerability in extension "KJ: Image Lightbox v2" (kj_imagelightbox2)

Dear users of TYPO3,

It has been discovered that the extension "KJ: Image Lightbox v2"
(kj_imagelightbox2) is susceptible to Cross Site Scripting (XSS) attacks.

==== Component Type ====
Third party extension. This extension is not part of the TYPO3 default
installation.

==== Affected Versions ====
Version 1.4.2 and below, possibly also all versions of obsolete
predecessor extension kj_imagelightbox

==== Vulnerability Type ====
Cross Site Scripting

==== Severity ====
Medium

==== Problem Description ====
Failing to filter user input the extension is susceptible to Cross Site
Scripting (XSS) making it possible to execute arbitrary JavaScript.

==== Solution ====
An updated version 1.4.3 is available from the TYPO3 extension manager
and at
<http://typo3.org/extensions/repository/view/kj_imagelightbox2/1.4.3/>.
Users of the extension are advised to update the extension as soon as
possible.

Users of the extension kj_imagelightbox, which is the predecessor of
kj_imagelightbox2, should switch to kj_imagelightbox2 1.4.3 too. The
predecessor might contain the same security issue, but is no longer part
of TER because the extension author decided to not maintain it any longer.

==== General advice ====
Follow the recommendations that are given in the TYPO3 Security Cookbook
[1]. If you haven't subscribed to the typo3-announce mailing list [2]
yet, please do so to receive future Security Bulletins via E-mail. All
TYPO3 Security Bulletins are available at the Security Team pages on
typo3.org [3].

==== Credits ====
Credits go to Michael Raberger, who discovered the issues. Furthermore
the TYPO3 Security Team wishes to thank the extension author Julian
Kleinhans for fixing the issue.

Regards,
Henning Pingel
