If applying the patch is not immediately feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These solutions can detect and block malicious network traffic, reducing the risk of successful exploitation.<br \/>\nHowever, these temporary measures should not replace the need for patching.
