AFFECTED APPLICATION OR SERVICE
TikiWiki
http://tikiwiki.org/

AFFECTED VERSION
1.9.x up to and including 1.9.2
Possibly versions < 1.9 (untested)

BACKGROUND
"Tikiwiki is a full featured Free Software (GNU/LGPL)
Wiki/CMS/Groupware written in PHP and maintained by an
active and international community of benevolent
contributors."

ISSUE 1 (XSS)
A XSS vulnerability has been detected in the fora code
of TikiWiki. The problem is caused by insufficient input
sanitation.

The following partial URL demonstrates the issue:

[baseURL]/tiki-view_forum_thread.php?forumId=1&comments_parentId=0&topics_offset=10%22%20onmouseover='javascript:alert(document.title)%3B'%3E[PLEASE%20MOVE%20YOUR%20MOUSE%20POINTER%20HERE!]%20%3Cx%20y=%22

Please move your mouse pointer over the input field
which says so.

ISSUE 2 (Information Disclosure, possible SQL injection)

The application discloses the installation path. This
may also be useable to craft an SQL injection.

The following partial URL demonstrates the issue:

[baseURL]/tiki-view_forum_thread.php?forumId=1&comments_parentId=0&topics_sort_mode=FOOBAH

WORKAROUND
Issue 1: Disable Javascript (client) or deny access to
TikiWiki (server).
Issue 2: Set PHP to log errors to file only (issue 2).

SOLUTIONS
We are not aware of a maintainer provided fix.
