Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement a workaround to mitigate the vulnerability
Implementing a workaround (such as a web application firewall rule or configuration change) reduces the immediate risk while waiting for a vendor patch. Developing a patch in-house is not advisable due to complexity and risk. Reporting to vendor is important but does not provide immediate protection. Disabling the service may be too disruptive.
