Softbiz FAQ is prone to multiple SQL injection vulnerabilities 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.
Softbiz FAQ 1.1 and prior versions are vulnerable; other versions may also be affected.
