A CVE score of 9.0 indicates what action should be taken?

• A. Ignore the vulnerability
• B. Monitor the vulnerability
• C. Replace the hardware
• D. Update firmware immediately

Answer: (D)

A CVSS score of 9.0 marks a vulnerability as critical with a high chance of being exploited and significant potential impact. In practice, this means remediation should be treated as an urgent priority and addressed as soon as possible. The most effective immediate action is to apply the vendor-provided firmware update that fixes the flaw, since updating the firmware directly patches the vulnerability in the device's software and reduces the attack surface. Ignoring a critical vulnerability or simply monitoring it leaves systems exposed to rapid exploitation, which is why those options aren’t suitable for a 9.0 score. Replacing hardware is not usually required as the primary response—patching with a firmware update is typically sufficient if the device remains supported and a fix is available. Only if a device cannot be patched or is end-of-life would alternative approaches or replacements be considered, but the standard and best practice is to update the firmware immediately.
