Description Jan Lieskovsky 2010-09-06 18:06:42 UTC

Moritz Naumann reported:
  [1] http://seclists.org/fulldisclosure/2010/Sep/82

a deficiency in the way Horde framework sanitized user-provided
'subdir' parameter, when composing final path to the image file.
A remote, unauthenticated user could use this flaw to conduct
cross-site scripting attacks (execute arbitrary HTML or scripting
code) by providing a specially-crafted URL to the running
Horde framework instance.

Upstream patch:
  [2] http://git.horde.org/diff.php/horde/util/icon_browser.php?rt=horde-git&r1=a978a35c3e95e784253508fd4333d2fbb64830b6&r2=9342addbd2b95f184f230773daa4faf5ef6d65e9

Sample public URL by Moritz to demonstrate the issue:
  [3] [path_to_horde]/util/icon_browser.php?subdir=<body onload="alert('XSS')">&app=horde

Comment 1 Jan Lieskovsky 2010-09-06 18:10:05 UTC

This issue affects the versions of the horde package, as shipped 
with Fedora release of 12 and 13.

(the relevant row is slightly different in Fedora Horde versions:

 if (($subdir = basename(Util::getFormData('subdir')))) {

), but the XSS is possible (verified on both versions).

Please fix.
