This vulnerability affects Cisco Firepower Threat Defense Software versions 6.1.x on the following vulnerable products that have enabled FDM: ASA5506-X ASA5506W-X ASA5506H-X ASA5508-X ASA5516-X ASA5512-X ASA5515-X ASA5525-X ASA5545-X ASA5555-X. More Information: CSCvb86860. Known Affected Releases: FRANGELICO. Known Fixed Releases: 6.2.0.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe vulnerability exists in the logging subsystem of Cisco Firepower Threat Defense (FTD) Firepower Device Manager (FDM), allowing an unauthenticated remote attacker to inject arbitrary entries into the audit log. This compromises log integrity but does not provide direct access to system functions or data exfiltration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Cisco FTD installationDetermine if the target system is running Cisco Firepower Threat Defense. This can be done by checking system information, checking for FTD-specific processes, or reviewing network footprint for FTD management interfaces.Affected if The system is confirmed to be running Cisco Firepower Threat Defense (FTD)
-
Check FTD software versionAccess the FTD device and retrieve the installed software version. This can typically be done via the CLI command 'show version' or through the FDM web interface by navigating to the System dashboard or About page.Affected if The installed version is exactly 6.1.0
-
Verify FDM accessibilityCheck if the Firepower Device Manager (FDM) web interface is accessible over the network. Attempt to reach the FDM login page on the standard HTTPS port (typically 443) for the FTD management IP address.Affected if FDM is exposed and reachable on the network
-
Confirm audit logging is enabledWithin the FDM interface, navigate to the logging or audit settings to verify if the audit logging subsystem is enabled and operational.Affected if Audit logging is enabled in the FDM logging subsystem
A system is affected if it is running Cisco Firepower Threat Defense version 6.1.0, has the FDM interface accessible, and has audit logging enabled, as the vulnerability allows log injection through the logging subsystem.
