Directly requires validation and sanitization of untrusted inputs such as the ID GET parameter before it reaches SQL processing in worksadd_plan.jsp.
Boundary protection devices (e.g., WAF or IPS rules) can inspect and block SQL injection payloads in HTTP requests to the vulnerable endpoint.
Continuous monitoring of application and database logs can identify anomalous SQL syntax or error patterns indicative of injection attempts against the ID parameter.
