Summary

Fix and mitigation
WAF and other mitigations
Can a WAF block it? No. The attack requires an authenticated attacker with internal network access, indicating it is not delivered via HTTP from outside but through internal network protocols. The malicious input is in URL parameters but since the attacker is authenticated and internal, the request looks normal to a WAF and cannot be reliably distinguished from legitimate traffic.
