CVE-2017-3822 Cisco CVE debrief

Who should care

Security teams operating Cisco Firepower Threat Defense 6.1.x appliances, especially ASA5506-X, ASA5506W-X, ASA5506H-X, ASA5508-X, ASA5516-X, ASA5512-X, ASA5515-X, ASA5525-X, ASA5545-X, and ASA5555-X deployments with Firepower Device Manager enabled. Logging, audit, and compliance owners should also care because the issue affects audit-log integrity.

Technical summary

NVD describes the flaw as a remote, network-reachable issue with no privileges or user interaction required, where the impact is limited to integrity of the audit log. The NVD CVSS v3.0 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N, and the weakness classification is CWE-20. The affected CPE entry in the source corpus maps to Cisco Firepower Threat Defense 6.1.0, with Cisco's advisory reference indicating the broader 6.1.x product line when Firepower Device Manager is enabled.

Defensive priority

Medium priority. The issue does not indicate confidentiality or availability impact, but it can undermine trust in audit records and complicate detection, investigation, and compliance workflows.

Recommended defensive actions

• Upgrade affected Cisco Firepower Threat Defense deployments to the fixed release noted in the source corpus: 6.2.0.
• Verify whether Firepower Device Manager is enabled on any vulnerable ASA5506-X/5506W-X/5506H-X/5508-X/5516-X/5512-X/5515-X/5525-X/5545-X/5555-X appliances running 6.1.x.
• Review audit-log integrity controls and alerting to detect unexpected or inconsistent log entries.
• Use the Cisco vendor advisory and NVD record to confirm exposure scope against your environment.
• Prioritize remediation where audit logs are used for incident response, compliance evidence, or security monitoring.
