"According to its self-reported version number, the Cacti application
running on the remote web server is prior to version 0.8.8b. It is,
therefore, potentially affected by command injection and SQL injection
vulnerabilities because the application fails to properly sanitize
user-supplied input to various scripts. An attacker may be able to
exploit these issues to execute arbitrary code as well as access or
modify the underlying database for the application.");
