http://secunia.com/advisories/19478/

CRITICAL:
Highly critical

IMPACT:
Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
Crafty Syntax Image Gallery 3.x
http://secunia.com/product/9171/

DESCRIPTION:
r0t has discovered some vulnerabilities in Crafty Syntax Image
Gallery, which can be exploited by malicious users to compromise a
vulnerable system and by malicious people to conduct SQL injection
attacks.

1) Input passed to the "limitquery_s" parameter in slides.php is not
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Images are not properly verified during the upload process. This
can be exploited to execute arbitrary PHP code by uploading PHP
scripts using manipulated HTTP POST data.

Successful exploitation requires privileges to upload images.

The vulnerabilities have been confirmed in version 3.1g. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
Allow only trusted users to upload images.
