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 · unedited
The Cisco Discovery Protocol (CDP) implementation on Cisco TelePresence Multipoint Switch before 1.9.0, Cisco TelePresence Immersive Endpoint Devices before 1.9.1, Cisco TelePresence Manager before 1.9.0, and Cisco TelePresence Recording Server before 1.8.1 allows remote attackers to execute arbitrary code by leveraging certain adjacency and sending a malformed CDP packet, aka Bug IDs CSCtz40953, CSCtz40947, CSCtz40965, and CSCtz40953.

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 confidence

A remote code execution vulnerability exists in the Cisco Discovery Protocol (CDP) implementation on multiple Cisco TelePresence products (Multipoint Switch, Immersive Endpoint Devices, Manager, and Recording Server). Attackers who have adjacency to the affected device can exploit this by sending a malformed CDP packet, allowing execution of arbitrary code with elevated privileges.

MitigationApply vendor-supplied software updates: TelePresence Multipoint Switch to 1.9.0+, Immersive Endpoint Devices to 1.9.1+, Manager to 1.9.0+, and Recording Server to 1.8.1+. As a compensating control, restrict physical/network access to limit which hosts can send CDP packets.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the TelePresence product type
    Determine which Cisco TelePresence product is running. Common commands include: 'show version', 'systemctl status', or check the device management interface for the product name (Multipoint Switch, System 1300, System 3000, System 3010, System 3200, System 3210, Immersive Endpoint, Manager, or Recording Server).
    Affected if The device is any of the affected TelePresence product lines listed in the CVE.
  2. Determine the software version
    Run 'show version' on the device CLI, or access the web admin interface to find the software/firmware version. For Multipoint Switch, look for version numbers like 1.x.x.
    Affected if The installed version matches any version listed in the CVE affected versions, or for products marked 'all versions', any version is vulnerable.
  3. Verify CDP is enabled
    Check if Cisco Discovery Protocol is active. On most devices, run 'show cdp neighbor' or 'show cdp' from the CLI. In the web interface, look under Network or Interface settings for CDP configuration.
    Affected if CDP is enabled and the device is directly accessible on the network segment ( Layer 2 adjacency).
  4. Assess network exposure
    Determine if untrusted physical or network access is possible. Check which devices can send CDP packets to the affected device. Verify if the network segment where the TelePresence device resides is properly segmented or has access controls.
    Affected if The device is on a network segment where untrusted or unauthorized devices can send CDP frames directly to the affected device.

A user is affected if they run any of the listed TelePresence products at the specified versions (or any version for 'all versions' entries) with CDP enabled and with network adjacency possible from untrusted hosts.

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 data
Upgrade available Upgrade to a release after 1.9.0.1
Interim mitigation

Apply vendor-supplied software updates: TelePresence Multipoint Switch to 1.9.0+, Immersive Endpoint Devices to 1.9.1+, Manager to 1.9.0+, and Recording Server to 1.8.1+. As a compensating control, restrict physical/network access to limit which hosts can send CDP packets.
