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 administrative web interface on Cisco TelePresence Multipoint Switch (CTMS) devices with software 1.0.x, 1.1.x, 1.5.x, and 1.6.x allows remote authenticated users to cause a denial of service or have unspecified other impact via vectors involving access to a servlet, aka Bug ID CSCtf97164.

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

The administrative web interface on Cisco TelePresence Multipoint Switch (CTMS) devices running software versions 1.0.x, 1.1.x, 1.5.x, and 1.6.x contains a vulnerability in a servlet that allows remote authenticated users to cause denial of service or achieve unspecified other impact. This is an authenticated vulnerability requiring valid administrative credentials.

MitigationRestrict administrative web interface access to trusted networks or IP ranges, and update affected CTMS devices to a patched software version if available from Cisco.

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 device model
    Access the device CLI or administrative interface and retrieve the hardware model information. For Cisco TelePresence Multipoint Switch, check the product identifier or use 'show version' command output.
    Affected if The device model is Cisco TelePresence Multipoint Switch (CTMS)
  2. Check the software version
    Use the CLI command 'show version' or access the administrative web interface to view the installed software version. Compare against the affected versions: 1.0.4.0, 1.1.0, 1.1.1, 1.1.2, 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, 1.5.6, and 1.6.0.
    Affected if The installed software version matches one of the listed affected versions
  3. Confirm administrative web interface is enabled
    Check the device configuration for the HTTP/HTTPS web interface service. Use 'show running-config' or similar command to verify if the web-based administrative interface (servlet) is currently enabled.
    Affected if The administrative web interface servlet is enabled and accessible
  4. Assess network exposure of the administrative interface
    Review firewall rules, ACLs, or network segmentation to determine if the administrative web interface is reachable from untrusted networks. Check which IP addresses are permitted to access the web interface.
    Affected if The administrative web interface is accessible from untrusted or external networks without proper access controls

The environment is affected if the device is a Cisco TelePresence Multipoint Switch running any of the listed software versions and the administrative web interface servlet is enabled and exposed.
