The remote host is vulnerable to a SQL Injection attack
The remote host seems to be running Snitz Forum, a web forum application implemented in ASP. This version of Snitz is reported vulnerable to a SQL injection flaw within the 'email' parameter of the 'register.asp' script. An attacker, exploiting this flaw, would send specially formed HTTP queries to the register.asp script. These queries would include SQL statements which would ultimately be executed on the database utilized by Snitz.
Upgrade to Snitz Forum 3.4.0.08 or higher
