TITLE:
TPO Duyuru Scripti Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA38045

VERIFY ADVISORY:
http://secunia.com/advisories/38045/

DESCRIPTION:
A security issue and some vulnerabilities have been reported in TPO
Duyuru Scripti, which can be exploited by malicious people to bypass
certain security restrictions, and conduct SQL injection and
cross-site request forgery attacks.

1) An error within the authentication mechanism in duyuruyonetim.php
can be exploited to bypass the authentication mechanism by setting
the "kullanici" cookie to "admin".

2) Input passed to the "kullaniciadi" parameter in yonetim_giris.php
is not properly sanitised before being used in SQL queries. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

3) The application allows administrators to perform certain actions
via HTTP requests without performing any validity checks to verify
the requests. This can be exploited to e.g. delete messages if a
logged-in administrator visits a specially crafted web site.

SOLUTION:
Restrict access to the duyuruyonetim.php script (via e.g. via
.htaccess).

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

Do not browse untrusted websites or follow untrusted links while
logged in to the application.

PROVIDED AND/OR DISCOVERED BY:
1) Septemb0x
2, 3) An anonymous person
