DeltaScripts PHP Links is prone to multiple SQL-injection vulnerabilities because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.

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

DeltaScripts PHP Links 2012 is vulnerable; other versions may also be affected.
