TITLE:
Graugon Gallery Security Bypass and SQL Injection

SECUNIA ADVISORY ID:
SA33922

VERIFY ADVISORY:
http://secunia.com/advisories/33922/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Graugon Gallery 1.x
http://secunia.com/advisories/product/21383/

DESCRIPTION:
x0r has discovered some vulnerabilities in Graugon Gallery, which can
be exploited by malicious people to bypass certain security
restrictions and conduct SQL injection attacks.

1) The application allows access to the administration interface by
checking if a certain cookie exists. This can be exploited to gain
administrative access to the application by creating the cookie
"g_admin" and assigning it the value "1".

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

These vulnerabilities are confirmed in version 1.0. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that proper access restrictions are
implemented and input is properly sanitised.
