CVE-2016-6452
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 graphical user interface (GUI) of Cisco Prime Home could allow an unauthenticated, remote attacker to bypass authentication. The attacker could be granted full administrator privileges. Cisco Prime Home versions 5.1.1.6 and earlier and 5.2.2.2 and earlier have been confirmed to be vulnerable. Cisco Prime Home versions 6.0 and later are not vulnerable. More Information: CSCvb71732.

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 Prime Home version via web GUIAccess the Cisco Prime Home web interface login page and look for the version number in the page footer or navigate to the About/Help section to find the version informationAffected if The version displayed is 5.1.1.6 or earlier, OR 5.2.2.2 or earlier, OR shows 5.0_base, 5.1_base, or 5.2.0
-
Identify Cisco Prime Home version via command lineIf you have SSH or console access to the Cisco Prime Home server, log in and check the version using commands such as 'show version' or by inspecting installation directories if documented in your deployment guidesAffected if The version displayed matches any of the affected versions listed in the CVE (5.1.1.6 and earlier, 5.2.2.2 and earlier, or 5.0_base, 5.1_base, 5.2.0)
-
Verify web-based GUI is accessibleConfirm that the Cisco Prime Home web interface is reachable on the network by attempting to access the login page via HTTP/HTTPS from a remote locationAffected if The web interface is exposed and the version is confirmed as vulnerable per the version checks above
-
Check for unauthorized administrator accountsLog into the Cisco Prime Home administrative interface and review the User Management or Administrator accounts section to identify any unexpected or unauthorized accounts that may indicate exploitationAffected if New or unknown administrator accounts exist that were not created by your authorized administrators
Your environment is affected if Cisco Prime Home is running version 5.1.1.6 or earlier, version 5.2.2.2 or earlier, or versions 5.0_base, 5.1_base, or 5.2.0, AND the web-based GUI is network-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.
dbcve · scopedUpgrade Cisco Prime Home to version 6.0 or later, which is not vulnerable. For environments unable to upgrade immediately, implement network segmentation to restrict access to the management interface.
Cisco Prime Home version 6.0 or later
- 1. Identify the current version of Cisco Prime Home installed by checking the About or version information in the web GUI or system documentation.
- 2. If the installed version is 5.0.x, 5.1.x through 5.1.1.6, or 5.2.x through 5.2.2.2, the system is vulnerable and requires an upgrade.
- 3. Plan for upgrade to Cisco Prime Home version 6.0 or later, as this version is confirmed NOT vulnerable.
- 4. Before upgrading, review Cisco Prime Home 6.0 release notes and upgrade documentation for any prerequisites, compatibility requirements, or migration procedures.
- 5. Perform a full backup of the current Cisco Prime Home installation including configuration files and database.
- 6. Follow Cisco's official upgrade procedure for Prime Home, typically executed through the web interface or command-line interface with appropriate privileges.
- 7. After upgrade, verify the new version number matches 6.0 or later.
- 8. Test that authentication is functioning properly and the previously vulnerable authentication bypass is no longer exploitable.
