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 Recording Server devices with software 1.6.x and Cisco TelePresence Multipoint Switch (CTMS) devices with software 1.0.x, 1.1.x, 1.5.x, and 1.6.x allows remote attackers to create or overwrite arbitrary files, and possibly execute arbitrary code, via a crafted request, aka Bug IDs CSCth85786 and CSCth61065.

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 Recording Server (1.6.x) and Cisco TelePresence Multipoint Switch (1.0.x-1.6.x) contains a file write vulnerability allowing unauthenticated remote attackers to create or overwrite arbitrary files on the system via crafted HTTP requests, leading to arbitrary code execution.

MitigationApply Cisco patches for Bug IDs CSCth85786 and CSCth61065 if available; otherwise restrict or disable the administrative web interface and 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 Cisco TelePresence Recording Server or Multipoint Switch installation
    Check system inventory, running processes, or network scans for the presence of Cisco TelePresence Recording Server or Multipoint Switch services. Look for processes named 'cts' or 'telepresence' or services listening on typical TelePresence management ports.
    Affected if Either Cisco TelePresence Recording Server or Multipoint Switch is installed on the system
  2. Determine the installed software version
    Access the administrative web interface and navigate to the About or System Information page, or use the command-line interface if available: 'show version' or 'show system'. Compare the version number against the affected ranges: Recording Server 1.6.1, 1.6.2, 1.6.3, or any 1.6.x; Multipoint Switch 1.0.4.0, 1.1.0 through 1.1.2, 1.5.0 through 1.5.6, or 1.6.0.
    Affected if The installed version matches one of the listed affected versions or falls within 1.0.x to 1.6.x for Multipoint Switch or 1.6.x for Recording Server
  3. Verify if the administrative web interface is enabled and accessible
    Attempt to access the administrative web interface via HTTP or HTTPS on the default management ports (typically 80, 443, or 8080). Check the device configuration for 'ip http server' or 'ip https server' status, and review access control lists governing the management interface.
    Affected if The administrative web interface is enabled and reachable from any network segment
  4. Check for unauthorized files or script modifications
    Inspect the web root directory (commonly /var/www or /usr/local/apache2/htdocs on the TelePresence device) for unexpected files with extensions such as .php, .jsp, .asp, .sh, or .cgi that were not authored by the administrator. Also review the /tmp directory for newly created scripts.
    Affected if Unexpected files exist in web-accessible directories or system temporary directories, indicating potential exploitation
  5. Review HTTP access and error logs for anomalous file write attempts
    Examine web server access logs and error logs for requests containing path traversal patterns (such as '../' or '..\'), unusual HTTP methods, or requests to endpoints that accept file uploads to non-standard paths. Look for HTTP 200 or 201 responses to suspicious paths.
    Affected if Logs contain evidence of file write attempts or successful uploads to arbitrary paths

A user is affected if they have Cisco TelePresence Recording Server (any 1.6.x version) or Multipoint Switch (1.0.x-1.6.x) installed with the administrative web interface enabled, regardless of version specificity.
