CVE-2019-15277
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 CLI of Cisco TelePresence Collaboration Endpoint (CE) Software could allow an authenticated, local attacker to execute code with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by authenticating as the remote support user and sending malicious traffic to a listener who is internal to the device. A successful exploit could allow the attacker to execute commands 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 · moderate confidenceThis is a local privilege escalation vulnerability in the CLI of Cisco TelePresence Collaboration Endpoint (CE) Software. An attacker who can authenticate as the 'remote support user' can send specially crafted malicious traffic to an internal listener, and due to insufficient input validation, achieve arbitrary code execution with root privileges.

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.
-
Confirm Cisco TelePresence CE software is runningIdentify the device as a Cisco TelePresence Collaboration Endpoint system by reviewing system information via the administrative interface or CLI command that displays the software platform.Affected if The device is running Cisco TelePresence Collaboration Endpoint (CE) Software.
-
Check installed software versionRetrieve the current software version using the appropriate command or interface that displays the CE software version number.Affected if The installed version is lower than 9.8.0 (for example, 9.7.x, 9.6.x, etc.).
-
Verify remote support user account statusCheck whether the 'remote support user' account exists and is enabled on the system through user account configuration settings or CLI commands that list local accounts.Affected if The 'remote support user' account is present and enabled on the device.
-
Assess remote support user authentication capabilityDetermine if the remote support user can authenticate to the device by verifying account credentials and access methods.Affected if The remote support user account can authenticate using its configured password.
A device is affected if it runs Cisco TelePresence CE software version below 9.8.0 and the remote support user account is enabled and accessible for authentication.

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 data9.8.0
Immediately change the default password for the remote support user account and disable the account if not required for legitimate support operations. Restrict physical and local network access to prevent unauthorized individuals from authenticating to the device.
