Package        : ikiwiki
Vulnerability  : missing input validation
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2011-1401

Tango discovered that ikiwiki, a wiki compiler, is not validating
if the htmlscrubber plugin is enabled or not on a page when adding
alternative stylesheets to pages.  This enables an attacker who is able
to upload custom stylesheets to add malicious stylesheets as an alternate
stylesheet, or replace the default stylesheet, and thus conduct
cross-site scripting attacks.


The oldstable distribution (lenny), this problem has been fixed in
version 2.53.6.

version 3.20100815.7.
