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
Anviz CX2 Lite is vulnerable to an authenticated command injection via a filename parameter that enables arbitrary command execution (e.g., starting telnetd), resulting in root‑level access.

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 Anviz CX2 Lite biometric device suffers from an authenticated command injection vulnerability in the filename parameter. An authenticated attacker can inject arbitrary OS commands through this parameter, achieving root-level command execution on the device, such as starting telnetd.

MitigationImplement strict input validation and sanitization for the filename parameter to prevent command injection; update to vendor-patched firmware if available; apply network segmentation and restrict administrative access as compensating controls.

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 Anviz CX2 Lite device on your network
    Scan network for Anviz CX2 Lite devices by checking device web interface banner, DHCP logs, or SNMP device enumeration. Look for vendor identifier 'Anviz' and model 'CX2 Lite' in device metadata.
    Affected if Device is confirmed as Anviz CX2 Lite access control device
  2. Confirm management interface accessibility
    Perform network port scan targeting the device. Check if HTTP/HTTPS management ports are listening and accessible from network segments that contain untrusted users or are internet-facing.
    Affected if Device management interface is reachable from untrusted network segments
  3. Verify authentication configuration
    Access device web interface and review authentication settings. Check whether default credentials are still in use or if weak/simple passwords are configured.
    Affected if Default credentials are active or weak authentication is configured
  4. Review logs for command injection indicators
    Examine device system logs and network traffic logs for patterns indicating command injection attempts. Look for unusual command strings, shell metacharacters, or unexpected system commands in request histories.
    Affected if Logs show command injection attempts or unauthorized command execution
  5. Check for unexpected system behavior
    Monitor device for abnormal behavior such as unexpected network connections, new processes, or modifications to system files that may indicate successful exploitation.
    Affected if Device exhibits signs of compromise or unauthorized command execution

You are affected if you have an Anviz CX2 Lite device with its management interface accessible from an untrusted network and the device uses default or weak authentication credentials.
