Alguest 1.1 - 'start' SQL Injection
source: https://www.securityfocus.com/bid/45214/info
Alguest is prone to an SQL-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query.
A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database.
Alguest 1.1c-patched is vulnerable; other versions may also be affected.
