TITLE:
PmWiki "width" Script Insertion Vulnerability

SECUNIA ADVISORY ID:
SA39698

VERIFY ADVISORY:
http://secunia.com/advisories/39698/

DESCRIPTION:
Hanno Boeck has discovered a vulnerability in PmWiki, which can be
exploited by malicious people to conduct script insertion attacks.

Input passed via the "width" markup while creating a table is not
properly sanitised before being displayed to the user. This can be
exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when the malicious data is being viewed.

The vulnerability is confirmed in version 2.2.15. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
