Until a fix is available, restricting access to the vulnerable admin.mbnetj.php interface and applying compensating controls to limit exposure may reduce risk.
Description
A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the admin.mbnetj.php files UpdateParam function due to improper neutralization of special elements in a SQL UPDATE command allowing for reading the whole database and changing values in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.
