TITLE:
2z project Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28244

VERIFY ADVISORY:
http://secunia.com/advisories/28244/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
2z project 0.x
http://secunia.com/product/14329/

DESCRIPTION:
Alexandr Polyakov and Stas Svistunovich have reported some
vulnerabilities in 2z project, which can be exploited by malicious
people to conduct cross-site scripting attacks and by malicious users
to conduct script insertion attacks.

1) Input passed to the "contentshort" and "contentfull" parameters in
actions/addnews.php is not properly sanitised before being stored.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site when the
malicious news is being viewed.

2) Input passed to the "content" parameter in actions/pm.php is not
properly sanitised before being stored. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site when the malicious message is being
viewed.

Successful exploitation of this vulnerability requires valid
administrator credentials.

3) Input passed via the URL is not properly sanitised in
templates/default/usermenu.tpl before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

4) Images uploaded through the "newavatar" and "newphoto" parameters
in profile.php are not properly sanitised before being stored. This
can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site when the
malicious profile is being viewed.

The vulnerabilities are reported in version 0.9.6.1. Other versions
may also be affected.

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