CVE-2016-6471
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 running FireSIGHT System software could allow an authenticated, remote attacker to view the Remote Storage Password. More Information: CSCvb19366. Known Affected Releases: 5.4.1.6.
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 confidenceCisco Firepower Management Center web-based management interface contains an information disclosure vulnerability allowing authenticated remote attackers to view the Remote Storage Password. The attacker needs valid credentials to access the web interface, but can then view stored sensitive credentials they should not have access to.

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 Firepower Management Center versionLog into the management console or run 'show version' via CLI to determine the Cisco Firesight/Firepower System Software versionAffected if The installed version is exactly 5.4.1.6
-
Confirm the web management interface is accessibleVerify the FTD/Firepower web-based management interface is enabled and reachable at the management center URLAffected if The web interface is accessible to the user (even with valid admin credentials, this is the attack vector)
-
Check if Remote Storage feature is configuredNavigate to System > Integration > Remote Storage in the web interface, or inspect the configuration for any configured remote storage endpointsAffected if Remote Storage is configured and a password is stored in the system
-
Verify user has web interface accessConfirm you have valid administrative credentials for the Firepower Management Center web interfaceAffected if You can authenticate to the web management interface - the vulnerability allows any authenticated user to view the Remote Storage Password they should not have access to
You are affected if your installed Cisco Firesight/Firepower System Software is version 5.4.1.6, the web management interface is accessible, and Remote Storage is configured with stored credentials.

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 the Cisco patch for this vulnerability (contact Cisco for updated releases beyond 5.4.1.6). If patching is immediately unavailable, restrict web management interface access to trusted admin networks only and enforce strong authentication for all accounts.
