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
Tenda AC18 V15.03.05.19 was discovered to contain a command injection vulnerability via the usbName parameter in the formSetSambaConf function.

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

Command injection vulnerability in Tenda AC18 router firmware V15.03.05.19. The usbName parameter in the formSetSambaConf function is not properly sanitized, allowing remote attackers to inject arbitrary OS commands via the parameter.

MitigationApply vendor firmware patch when available; until then, disable SAMBA/Samba functionality if not required, or restrict network access to the router's management interface.

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. Confirm Tenda AC18 router model
    Access the router web interface or check the device label/metadata to verify the model is Tenda AC18
    Affected if Device is not a Tenda AC18 router
  2. Check firmware version
    Navigate to the router admin panel (typically http://192.168.0.1) and look in System Settings or Administration > Firmware Upgrade to find the installed firmware version
    Affected if Firmware version is 15.03.05.19
  3. Verify SAMBA service is accessible
    Check if the router's SAMBA/Network Sharing feature is enabled in the router settings under USB Settings or Storage/Samba settings
    Affected if SAMBA functionality is enabled and accessible on the network
  4. Confirm web interface is reachable
    Verify the router's HTTP/HTTPS management interface is accessible on the local network (port 80/443)
    Affected if The web management interface is exposed and reachable

The device is affected if it is a Tenda AC18 router running firmware version 15.03.05.19 with the SAMBA/Network Sharing feature enabled, as the command injection vulnerability exists in the formSetSambaConf function's usbName parameter.
