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
A security vulnerability has been detected in UGREEN CM933 1.1.59.4319. The impacted element is an unknown function of the component Administrative Interface. Such manipulation leads to missing authentication. The attack requires being on the local network. You should upgrade the affected component. The vendor replied: "We have successfully confirmed and reproduced the issue. We take this matter very seriously and have incorporated the fix into our development schedule. The issue is scheduled to be resolved in the release version coming in late April."

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 UGREEN CM933 1.1.59.4319 network device contains a missing authentication vulnerability in its Administrative Interface, allowing unauthenticated attackers on the local network to access certain administrative functions without credentials.

MitigationRestrict network access to the device's administrative interface to trusted IPs or networks until the vendor patch is released in late April; apply the firmware update promptly when available.

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's web interface or check the device label/documentation to confirm the model is UGREEN CM933
    Affected if Device is not a UGREEN CM933 unit
  2. Check the firmware version
    Log into the device's administrative interface and navigate to Settings > System > Firmware Version (or similar) to view the installed firmware version
    Affected if Firmware version matches exactly 1.1.59.4319
  3. Verify administrative interface accessibility
    From a device on the same local network, attempt to access the device's admin interface by entering its IP address in a web browser
    Affected if The administrative interface loads without requiring any login credentials

You are affected if you have a UGREEN CM933 device running firmware version 1.1.59.4319 and the administrative interface is accessible without authentication
