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
Multiple vulnerabilities in the web engine of Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow a remote attacker to cause a denial of service (DoS) condition, view sensitive data on an affected device, or redirect users to an attacker-controlled destination. For more information about these vulnerabilities, see the Details section of this advisory.

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 confidence

Multiple vulnerabilities in the web engine of Cisco TelePresence CE and RoomOS Software allow remote attackers to cause denial of service, view sensitive device data, or redirect users to attacker-controlled destinations. The vulnerabilities stem from improper input validation and security controls in the web interface.

MitigationApply Cisco software updates for CE/RoomOS when available; disable or restrict web engine access if not required, or implement network segmentation to limit exposure.

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 your Cisco product type
    Log into the device admin interface or check the device型号 to confirm whether it is a Cisco Telepresence Collaboration Endpoint (CE) or a Cisco RoomOS device.
    Affected if The device is a Cisco Telepresence Collaboration Endpoint or Cisco RoomOS system.
  2. Determine the installed software version
    Access the device web interface or CLI and locate the software version information, typically found in the system status or version section.
    Affected if The version is below 10.8.2.5 for Cisco Telepresence CE, or the version date is before 2021-05 for Cisco RoomOS.
  3. Verify the web engine is enabled
    Check the device configuration settings for the web engine or web server status. This is usually found under Security, Network Services, or Web Access settings in the admin interface.
    Affected if The web engine web interface is enabled and accessible.
  4. Review web access exposure
    Examine the network configuration to determine if the web interface is reachable from untrusted networks, checking firewall rules, ACLs, or service bindings.
    Affected if The web interface is reachable from outside the trusted network or management VLAN.

You are affected if you are running Cisco Telepresence CE below version 10.8.2.5 or Cisco RoomOS before the 2021-05 release, and the web engine interface is enabled on your device.

Interim mitigation

Apply Cisco software updates for CE/RoomOS when available; disable or restrict web engine access if not required, or implement network segmentation to limit exposure.

Recommended fix High confidence

Cisco TelePresence Collaboration Endpoint (CE) version 10.8.2.5 or later / RoomOS version 2021-05 or later

  1. 1. Identify the current software version of the Cisco TelePresence device by accessing the admin interface or using the device's built-in diagnostics
  2. 2. Determine the device type: Cisco TelePresence Collaboration Endpoint (CE) or Cisco RoomOS
  3. 3. For TelePresence Collaboration Endpoint: upgrade to version 10.8.2.5 or later
  4. 4. For RoomOS: upgrade to version 2021-05 or later
  5. 5. Obtain the appropriate software update from Cisco's official download portal (software.cisco.com) using valid support credentials
  6. 6. Follow Cisco's standard firmware upgrade procedure for the specific device model - typically via the web interface or SSH access
  7. 7. After upgrade, verify the new version is installed and the device is operational
  8. 8. Test that the web engine functions normally and the open redirect vulnerability is remediated
