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 low privileged remote attacker can use a command injection vulnerability in the API which performs remote code execution as the user-app user due to improper input validation. The confidentiality is partly affected.

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

This is a command injection vulnerability in an API endpoint where improper input validation allows a low-privileged remote attacker to execute arbitrary code on the system. The attacker can achieve remote code execution as the limited 'user-app' user context, resulting in partial confidentiality impact.

MitigationImplement strict input validation and sanitization for all API parameters, preferably using allowlist validation or safe API methods that avoid shell command execution. Consider implementing API request validation frameworks and least-privilege execution contexts.

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 web interface, administrative console, or check the physical device label to confirm the exact model is one of: Charx Sec 3000, Charx Sec 3050, Charx Sec 3100, or Charx Sec 3150
    Affected if The device model matches one of the four affected product names
  2. Check the installed firmware version
    Log into the device administrative interface or use the device's firmware version check command (typically via web UI under System > Firmware or via CLI) and note the firmware version number
    Affected if The firmware version is 1.5.1 or lower (the vulnerable range is <= 1.5.1)
  3. Verify API endpoint exposure
    Determine if the device API endpoint is accessible from the network by checking the device network configuration, firewall rules, or attempting a local API request to the vulnerable endpoint path (consult device documentation for the specific API endpoint URL)
    Affected if The API endpoint is reachable from network locations outside the trusted administrative segment
  4. Confirm API authentication settings
    Check the device security configuration to determine if the API endpoint requires authentication and what privilege level is needed to access the vulnerable endpoint
    Affected if The API endpoint allows access from low-privileged or unauthenticated remote attackers
  5. Check for signs of compromise
    Review device logs, process lists, or network traffic logs for unexpected commands, unusual API calls, or evidence of shell command execution originating from the API interface
    Affected if Logs show unauthorized command execution or unexpected shell invocations

You are affected if your device is a Phoenixcontact Charx Sec 3000/3050/3100/3150 with firmware version 1.5.1 or lower AND the API endpoint is network-accessible to untrusted users.
