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
t0mer BroadlinkManager v5.9.1 was discovered to contain an OS command injection vulnerability via the IP Address parameter at /device/ping.

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

BroadlinkManager v5.9.1 contains an OS command injection vulnerability in the /device/ping endpoint where the IP Address parameter is not properly sanitized before being passed to a system call. An attacker can inject arbitrary OS commands through this parameter, potentially gaining unauthorized access to the underlying system.

MitigationImplement strict input validation for the IP Address parameter using an allowlist approach, and replace any shell command execution with parameterized methods or safe API alternatives that do not invoke shell interpreters.

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 BroadlinkManager installation
    Search for BroadlinkManager in your environment - check running processes, installed applications, or docker containers. Look for the application name 'BroadlinkManager' or 'broadlinkmanager'.
    Affected if BroadlinkManager is present in your environment
  2. Determine the installed version
    Check the version of BroadlinkManager by examining the application's about page, version file, docker image tag, or API endpoint that returns version information. Compare against the affected range <= 5.9.1.
    Affected if The installed version is 5.9.1 or any earlier version
  3. Verify /device/ping endpoint exists
    Attempt to access the /device/ping endpoint via HTTP GET or POST request to determine if the endpoint is exposed. This is typically found at http://[host]/device/ping.
    Affected if The /device/ping endpoint responds and accepts input
  4. Check for shell command execution in ping functionality
    Examine application logs, configuration, or source code if accessible. Look for evidence that the ping functionality invokes system shell commands rather than using safe API alternatives.
    Affected if The application uses shell execution (system(), exec(), popen(), or similar) to process the IP Address parameter in the ping endpoint

You are affected if BroadlinkManager version 5.9.1 or lower is installed and the /device/ping endpoint with shell-based command execution is accessible in your environment.

Upgrade available Upgrade to a release after 5.9.1
Interim mitigation

Implement strict input validation for the IP Address parameter using an allowlist approach, and replace any shell command execution with parameterized methods or safe API alternatives that do not invoke shell interpreters.

Recommended fix Moderate confidence

Latest available version > 5.9.1 (check GitHub releases for the current stable release)

  1. 1. Back up the current BroadlinkManager configuration and data
  2. 2. Stop the BroadlinkManager service
  3. 3. Download the latest version of BroadlinkManager from the official GitHub repository (github.com/t0mer/BroadlinkManager)
  4. 4. Install the updated version, ensuring it is newer than 5.9.1
  5. 5. Verify the /device/ping endpoint no longer accepts unsanitized input that could lead to OS command injection
  6. 6. Restart the BroadlinkManager service
  7. 7. Test that the ping functionality works correctly with valid IP addresses
  8. 8. Confirm the vulnerability is remediated by attempting injection via the IP parameter (should be sanitized or rejected)
