CVE-2019-12684
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 · uneditedMultiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary SQL injections on an affected device. These vulnerabilities exist due to improper input validation. An attacker could exploit these vulnerabilities by sending crafted SQL queries to an affected device. A successful exploit could allow the attacker to view information that they are not authorized to view, make changes to the system that they are not authorized to make, and execute commands within the underlying operating system that may affect the availability of the 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 confidenceMultiple SQL injection vulnerabilities exist in the web-based management interface of Cisco Firepower Management Center (FMC) Software due to improper input validation. An authenticated attacker can send crafted SQL queries to execute arbitrary SQL, potentially allowing unauthorized data access, system modifications, and OS command execution.

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 FMC software versionLog into the Firepower Management Center web interface and navigate to the System > Licenses > Product License page, or use the CLI and run 'show version' or 'system version' to retrieve the installed software version.Affected if The installed version is exactly 6.2.0, 6.2.2, or 6.2.3.
-
Confirm web-based management interface is enabledCheck if the FMC web interface is accessible and active by attempting to reach the management console URL or reviewing the HTTP/HTTPS service configuration on the FMC device.Affected if The web-based management interface is enabled and reachable.
-
Verify authentication is required for accessConfirm that the web management interface requires valid user credentials to access. Attempt an unauthenticated request to see if login is enforced.Affected if The interface accepts authentication credentials (meaning a compromised or stolen credential could be used to exploit the SQL injection).
The environment is affected if the installed Cisco FMC version is exactly 6.2.0, 6.2.2, or 6.2.3 and the web-based management interface is accessible to an authenticated attacker.

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's available patches for FMC Software. As an interim measure, limit access to the web management interface to trusted users only and monitor for suspicious SQL-like patterns in requests.
