CVE-2019-12689
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary code on the underlying operating system of an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending malicious commands to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system of the affected device.
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 confidenceA command injection vulnerability in Cisco FMC's web-based management interface allows authenticated remote attackers to execute arbitrary OS commands due to insufficient input validation on user-supplied data. The attacker sends malicious commands through the web interface, bypassing expected input controls.

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 FMC installationLocate the Cisco Firepower Management Center in your environment and confirm it is the affected product typeAffected if The system is Cisco Secure Firewall Management Center (formerly Firepower Management Center)
-
Check installed versionAccess the FMC web interface (typically https://<management_center_ip>/) and navigate to System > About > Updates or use the CLI command 'show version' to determine the exact version numberAffected if The installed version is lower than 6.2.2.2 (any version < 6.2.2.2 is affected)
-
Verify web management interface is enabledCheck if the FMC web-based management interface (HTTPS/HTTP) is enabled and accessible. This is typically configured under System > Configuration > Management Access in the FMC interfaceAffected if The web management interface is enabled and reachable (this is required for the vulnerability to be exploitable)
-
Assess authentication exposureReview who has administrative credentials for the FMC and whether the management interface is accessible from untrusted networksAffected if Administrative accounts exist and the web interface is accessible from network segments beyond the trusted administrative network
You are affected if Cisco Secure Firewall Management Center is installed with a version lower than 6.2.2.2 and the web-based management interface is enabled and accessible.

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 data6.2.2.2
Apply the vendor patch or upgrade Cisco FMC to a fixed version. Ensure web management interface is not exposed to untrusted networks and enforce least-privilege access for administrative accounts.
