Update Date: 11/05/09
Discovered by: Bkis
Attack Type: SQL Injection
Security Rating: Critical

2. Technical Description

SQL Injection occurs due to the software on Server can not strictly 
control the validity of variables transmitted from client before sending 
a query to the database. Hacker is able to take advantage of this 
vulnerability to insert malicious SQL code and then can manipulate all

organizations and individuals using eoCMS immediately update the latest
