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
Specific firmware versions of Milesight AIOT cameras use SSL certificates with default private keys.

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

Milesight AIOT cameras with specific firmware versions ship with hardcoded/default SSL private keys in their certificate infrastructure. This allows attackers to decrypt TLS communications, perform man-in-the-middle attacks, and potentially access camera feeds or authentication credentials, as the encryption provides no real security when the private key is publicly known.

MitigationUpdate affected cameras to patched firmware versions that use properly generated unique SSL certificates, and regenerate/replace any certificates deployed on affected devices with new uniquely-generated key pairs.

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 Milesight AIOT camera firmware version
    Access the camera web interface (usually via HTTP/HTTPS to the device IP), navigate to Settings > System > About, or use the ONVIF/SNMP interface to query the device firmware version. Alternatively, check the startup logs or system info page.
    Affected if The installed firmware version falls within the affected version range for Milesight AIOT cameras.
  2. Verify SSL/TLS is enabled on the camera
    Check the camera network settings through the web interface under Settings > Network > SSL/TLS, or examine the device configuration for enabled HTTPS/SSL services. Use a network scanner to confirm port 443 or other SSL-enabled ports are active.
    Affected if SSL/TLS encryption is enabled and the camera accepts HTTPS connections.
  3. Extract and inspect SSL certificates on the device
    Access the camera via SSH or FTP (if enabled) and navigate to the certificate storage directory (commonly /etc/ssl/certs, /mnt/config/ssl, or similar paths depending on firmware). Use openssl x509 -in certificate.pem -text -noout to inspect the certificate details.
    Affected if The device contains SSL certificates in the file system that can be extracted and examined.
  4. Check for hardcoded or default private keys
    Locate private key files (typically .key, .pem, or privatekey.pem files) in the SSL directories. Use openssl rsa -in privatekey.pem -check -noout to validate the key. Compare the extracted keys against known default/private key patterns or attempt to decode them to identify weak/hardcoded keys.
    Affected if The private keys are identical across multiple devices, use weak/default values, or match known hardcoded key patterns documented for this vulnerability.

A user is affected if running an affected Milesight AIOT camera firmware version that uses SSL certificates with hardcoded or default private keys, allowing potential decryption or MITM impersonation.
