TITLE:
Max.Blog "delete.php" Security Bypass Vulnerability

SECUNIA ADVISORY ID:
SA33590

VERIFY ADVISORY:
http://secunia.com/advisories/33590/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Max.Blog 1.x
http://secunia.com/advisories/product/21077/

DESCRIPTION:
SirGod has discovered a vulnerability in Max.Blog, which can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to the application not properly
restricting access to the "delete.php" script. This can be exploited
to delete arbitrary blog posts by requesting the delete.php script
(when "post" is set to a valid post ID and "confirm" is set to "yes")
directly.

This vulnerability is confirmed in version 1.0.6. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that proper access restrictions are
implemented.
