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 the installed productLog into the Cisco Firepower Management Center or FireSIGHT System Console and navigate to System > About > Updates or Help > About to confirm the product name and exact version numberAffected if Product is Cisco Firepower Management Center or Cisco Firesight System Software
-
Check the installed versionLocate the version number in the About page or via CLI command 'show version' and compare it to the affected versions: 6.0.0, 6.0.0.0, 6.0.0.1, 6.0.1, 6.0.1.1, 6.1.0Affected if Installed version matches one of the listed affected versions
-
Verify file policy configurationNavigate to Policies > Access Control > File Policy (or Policies > Malware Protection > File Policy in older interfaces) and examine if any file policy exists with the 'Block Malware' action enabledAffected if A file policy with 'Block Malware' action is active
User is affected if running an affected version (6.0.0 through 6.1.0) of Cisco Firepower Management Center or Firesight System Software AND has a file policy configured with the Block Malware action.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Cisco security updates when available. In the interim, augment file inspection with additional security controls such as endpoint protection, network segmentation, and enhanced monitoring for anomalous file transfers.
