VERIFY ADVISORY:
http://secunia.com/advisories/18572/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Pixelpost 1.x
http://secunia.com/product/6946/

DESCRIPTION:
Aliaksandr Hartsuyeu has discovered a vulnerability in Pixelpost,
which can be exploited by malicious people to conduct script
insertion attacks.

Input passed in user comments is not properly sanitised before being
used. This can be exploited to inject arbitrary HTML and script code,
which will be executed in e.g. an administrative user's browser
session when opening the "comments" menu in the admin CP.

Administrative users can also upload arbitrary files to locations
inside the web root.

The vulnerability has been confirmed in version 1.4.3. Other versions
may also be affected.

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

Don't grant administrative user privileges to untrusted people.
