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
Shenzen Tenda Technology IP Camera CP3 V11.10.00.2211041355 allows unauthenticated remote code execution via an XML document.

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

The Tenda IP Camera CP3 version V11.10.00.2211041355 contains an unauthenticated remote code execution vulnerability. Attackers can execute arbitrary code by submitting a specially crafted XML document to the affected device, likely through a parsing flaw in XML processing.

MitigationIsolate the affected camera from untrusted networks immediately using network segmentation. Contact Tenda for available firmware patches; if no patch exists, consider replacing the device with a supported model.

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 camera's web interface or check network discovery/UPnP responses for 'CP3' or 'Tenda' in the device description or hostname
    Affected if The device is not a Tenda CP3 camera - if it is CP3, proceed to next check
  2. Determine the firmware version
    Log into the camera's web interface and navigate to System Settings > Device Info, or query the device's /cgi-bin/login.cgi endpoint for version information
    Affected if The firmware version displayed is exactly 11.10.00.2211041355 - if different, the specific vulnerability may not apply
  3. Verify the web service is accessible
    Attempt to access the camera's HTTP port (typically 80 or 8080) from the network. Check if the XML parsing endpoint responds to HTTP POST requests
    Affected if The web interface is exposed and accepts unauthenticated requests to the XML processing endpoint - the vulnerability can be exploited if the service is reachable
  4. Check for recent device activity
    Review network logs or firewall logs for unusual XML-formatted HTTP POST requests to the camera's IP address from untrusted sources
    Affected if There are incoming POST requests to the camera that contain XML payload data, indicating active exploitation attempts

You are affected if you have a Tenda CP3 camera running firmware version 11.10.00.2211041355 with its web interface accessible on the network.

Mitigation

Isolate the affected camera from untrusted networks immediately using network segmentation. Contact Tenda for available firmware patches; if no patch exists, consider replacing the device with a supported model.
