Multiple SQL injection vulnerabilities in Zero CMS 1.0 Alpha allow remote attackers to execute arbitrary SQL commands via (1) the id parameter to index.php, or the (2) f or t parameters to forums/index.php.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component.
