TITLE:
Tr Forum SQL Injection and Security Bypass Vulnerabilities

SECUNIA ADVISORY ID:
SA21754

VERIFY ADVISORY:
http://secunia.com/advisories/21754/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Tr Forum 2.x
http://secunia.com/product/11833/

DESCRIPTION:
DarkFig has discovered some vulnerabilities in Tr Forum, which can be
exploited by malicious people to conduct SQL injection attacks and
bypass certain security restrictions.

1) Missing authentication verification in admin/insert_admin.php can
be exploited to create an administrator account with limited
privileges.

2) Input passed to the "id2" parameter in admin/editer.php isn't
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires certain administrative privileges.

3) Missing access verification when updating the profile can be
exploited to modify other users' settings by changing the "id"
parameter.

A combination of vulnerabilities #1 and #2 can be exploited to access
the administrative section with full privileges.

The vulnerabilities have been confirmed in version 2.0. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified, and restrict access to the admin/insert_admin.php script.
