CVE-2016-6459
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 · uneditedCisco TelePresence endpoints running either CE or TC software contain a vulnerability that could allow an authenticated, local attacker to execute a local shell command injection. More Information: CSCvb25010. Known Affected Releases: 8.1.x. Known Fixed Releases: 6.3.4 7.3.7 8.2.2 8.3.0.
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 TelePresence endpoints running CE or TC software versions 8.1.x contain a local shell command injection vulnerability. An authenticated, local attacker with access to the device can inject and execute arbitrary shell commands due to insufficient input validation in the authentication subsystem.

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 device typeAccess the Cisco TelePresence endpoint via its web interface, CLI (SSH or console), or administrative console. Confirm the device is a Cisco TelePresence endpoint and note whether it runs CE software or TC software.Affected if The device is not a Cisco TelePresence endpoint running CE or TC software.
-
Determine the exact software versionIn the CLI, run the command 'show version' or 'xversion'. In the web interface, navigate to Home > System Information or similar. Record the full version number (e.g., 8.1.0, 7.3.3).Affected if The installed version cannot be determined or is not visible.
-
Compare version against the affected listCheck if the installed version matches exactly one of these: 7.1.0, 7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.3.0, 7.3.1, 7.3.2, 7.3.3, 8.0.0, or 8.1.0Affected if The installed version exactly matches any version in the list.
-
Verify local authentication is enabledCheck the authentication configuration in the web interface under Administration > Security > Authentication, or via CLI command 'show running-config | include auth' to confirm local user authentication is configured.Affected if Local authentication is enabled and users can access the device locally.
You are affected if you have a Cisco TelePresence endpoint running TC or CE software with a version that exactly matches 7.1.0-7.1.4, 7.3.0-7.3.3, 8.0.0, or 8.1.0 and local authentication is configured.

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 dataUpgrade Cisco TelePresence endpoints from affected versions (8.1.x) to fixed releases (6.3.4, 7.3.7, 8.2.2, or 8.3.0) as appropriate for the deployment. Coordinate maintenance window to avoid disruption.
