CVE-2019-12694
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 command line interface (CLI) of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker with administrative privileges to execute commands on the underlying operating system with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by executing a specific CLI command that includes crafted arguments. A successful exploit could allow the attacker to execute commands on the underlying OS with root privileges.
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 local privilege escalation vulnerability in Cisco Firepower Threat Defense (FTD) CLI allows authenticated administrators with existing privileges to execute arbitrary operating system commands with root privileges due to insufficient input validation when specific CLI commands with crafted arguments are executed.

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.
-
Determine installed FTD versionAccess the FTD CLI and run the command 'show version' or 'show running-config | include version' to display the installed software versionAffected if The displayed version falls within < 6.3.0.5 or >= 6.4.0 and < 6.4.0.4
-
Compare version against affected rangesReview the version output from step 1 against the known affected ranges: versions prior to 6.3.0.5, and versions 6.4.0 through 6.4.0.3Affected if The installed version matches one of these ranges (< 6.3.0.5 or >= 6.4.0, < 6.4.0.4)
-
Verify CLI access is enabledConfirm that the FTD CLI management interface is accessible and authentication is configured. Check via 'show managers' or review management access settingsAffected if CLI management is enabled and user authentication is configured for administrative access
-
Check for vulnerable CLI command behaviorTest or audit CLI command execution with privileged admin accounts. The vulnerability allows privilege escalation when specific CLI commands accept crafted argumentsAffected if An authenticated administrator with standard privileges can execute arbitrary OS commands with root privileges through the CLI
The environment is affected if the installed FTD version is less than 6.3.0.5 or falls between 6.4.0 and 6.4.0.3, and the CLI interface is accessible to authenticated administrators.
