What should you do?
- Read the full vendor advisory linked below and confirm whether you run affected versions.
- Schedule the recommended update, prioritising internet-facing systems.
- Watch for exploitation reports; unpatched edge devices are frequent targets.
What to do and how to stay safe: Cisco PSIRT
- Patch scores alone ignore context like network exposure and asset criticality.
- You must map vulnerabilities to specific business risks to prioritize correctly.
- Continuous exposure data replaces static scanning for accurate prioritization.
Prioritize vulnerabilities by actual exploitability and business impact, not by theoretical severity scores. Update your asset context and exposure data continuously to maintain accurate risk rankings.
