Description Tomas Hoger 2008-09-11 03:40:26 EDT
oCERT reported an XSS vulnerability discovered by Alexios Fakos affecting horde: 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. For example, the following snippet, supplied by the reporter, is treated as valid by the browsers but safe by the filter: <body/onload=alert(/w00w00/)> According to oCERT, this affects 3.1.x and 3.2.x versions of Horde, possibly others.

Comment 2 Chris Croome 2008-12-25 18:26:41 EST
Horde Application Framework version 3.2.2 announced on September 10th 2008 fixed this: The Horde Team is pleased to announce the final release of the Horde Application Framework version 3.2.2. This is a security release that fixes unescaped output in the MIME library (CVE-2008-3823), and further improves the XSS filter for HTML messages (CVE-2008-3824). The unescaped output vulnerability can be triggered by sending specially crafted e-mail messages to Horde users, if they use a Horde mail client. All users are encouraged to upgrade to this version. The major changes compared to the Horde version H3 (3.2.1) are: * Fixed unescaped output in the MIME library. * Further improved the XSS filter for HTML. http://lists.horde.org/archives/announce/2008/000429.html In addition on December 10th 2008 version 3.2.3 was released: This is a minor security release that adds another check to the XSS filter for an Internet Explorer exploit. All users are encouraged to upgrade to this version. The major changes compared to the Horde version H3 (3.2.2) are: * Added another check to the XSS filter (only IE is vulnerable). http://lists.horde.org/archives/announce/2008/000462.html There is also a 3.3.2 version but I guess that this would be a more complicated upgrade. I haven't tested for this XSS exploit -- my interest in a 3.2.2 version of Horde is so that I can install Ansel: Ansel 1.0 requires version 3.2.2 or greater of the Horde Framework - earlier versions of Horde will not work. http://www.horde.org/ansel/docs/?f=INSTALL.html#prerequisites I'm using the epel-5 package.
