#2008-012 Horde, Popoon frameworks common input sanitization errors (XSS)

Two cross-site scripting (XSS) vulnerabilities were reported in Horde
Framework. The first of which is that the Horde framework fails to
properly
sanitize the filename of MIME attachments on received emails. The second
vulnerability has a wider impact.

Horde relies on code similar to Popoon\'s externalinput.php to filter out
potential XSS attacks on user-supplied input. This filter, and the
original,
fail to fully sanitize user data. In particular, this filter fails to
protect against \'/\'s acting as spaces in both Microsoft Internet Explorer
and
Mozilla Firefox.

Patches have been made available for Horde:

* 3.1:
http://ocert.org/patches/2008-012/Text_Filter.31.patch
* 3.2 - CVS HEAD:
http://ocert.org/patches/2008-012/MIME.patch
http://ocert.org/patches/2008-012/Text_Filter.patch

A replacement for externalinput.php is linked below as well.
