Summary

CVE-2022-50691 is a critical-severity OS Command Injection (CWE-78) vulnerability in Minidvblinux Minidvblinux. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 34.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2022-50691 is a remote command execution vulnerability in MiniDVBLinux 5.4, classified under CWE-78 (OS Command Injection). The issue stems from the /tpl/commands.sh endpoint, which processes the 'command' GET parameter without proper sanitization, enabling attackers to inject and execute arbitrary commands.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no privileges or user interaction required, as reflected in its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Successful exploitation allows attackers to execute commands as root, resulting in complete system compromise with high impacts on confidentiality, integrity, and availability.
