SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/17858/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
PHPX 3.x
http://secunia.com/product/2967/

DESCRIPTION:
rgod has reported a vulnerability in PHPX, which can be exploited by
malicious people to conduct SQL injection attacks and compromise a
vulnerable system.

Input passed to the "username" field when logging into the
administration section isn't properly sanitised before being used in
a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

This can further be exploited to bypass the authentication process
and access the administration section where arbitrary PHP scripts can
be uploaded and executed.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been reported in version 3.5.9 and prior. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
