CVE-2022-50691
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 · uneditedMiniDVBLinux 5.4 contains a remote command execution vulnerability that allows unauthenticated attackers to execute arbitrary commands as root through the 'command' GET parameter. Attackers can exploit the /tpl/commands.sh endpoint by sending malicious command values to gain root-level system 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 confidenceMiniDVBLinux 5.4 has an unauthenticated remote command execution vulnerability in the /tpl/commands.sh endpoint. Attackers can inject arbitrary shell commands through the 'command' GET parameter and execute them with root privileges, achieving full system compromise.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify MiniDVBLinux versionLocate and inspect the installed MiniDVBLinux version on the system. This may be found in system information, package management tools, or the /etc/VERSION file if it exists. Compare the installed version to the affected range (5.4).Affected if The installed version is MiniDVBLinux 5.4 exactly
-
Locate the vulnerable endpointCheck for the presence of the /tpl/commands.sh script in the web server's document root or application directory. This file is typically located in the web interface directories of MiniDVBLinux.Affected if The /tpl/commands.sh file exists on the system
-
Verify network accessibilityDetermine if the web interface or API service that hosts /tpl/commands.sh is exposed to the network. Check firewall rules, listening services, and network configuration to see if remote clients can reach the web service.Affected if The endpoint is accessible from network locations beyond localhost
-
Confirm authentication statusTest whether the /tpl/commands.sh endpoint requires authentication. Attempt an unauthenticated request to this endpoint to see if it processes commands without credentials.Affected if The endpoint accepts and processes requests without requiring authentication
A system is affected if MiniDVBLinux version 5.4 is installed and the /tpl/commands.sh endpoint is network-accessible without authentication requirements.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately restrict network access to the /tpl/commands.sh endpoint, implement authentication requirements, and apply any available vendor patches. Consider network segmentation to limit exposure of the affected service.
