A critical vulnerability has been identified in multiple MiniDVBLinux products, designated CVE-2022-50691. This flaw allows any unauthenticated attacker on the network to remotely execute arbitrary commands with the highest system privileges (root), leading to a complete compromise of the affected device. Due to the ease of exploitation and the severity of its impact, this vulnerability poses a significant and immediate threat to the confidentiality, integrity, and availability of the system.

Vulnerability Details

CVE-ID: CVE-2022-50691

Affected Software: MiniDVBLinux Multiple Products

Affected Versions: Version 5.4. See vendor advisory for specific affected versions.

Vulnerability: This is an unauthenticated remote command execution (RCE) vulnerability. The /tpl/commands.sh script improperly handles user-supplied input from the 'command' GET parameter. An attacker can craft a malicious HTTP GET request to this endpoint, embedding arbitrary system commands within the 'command' parameter, which are then executed on the underlying operating system with root privileges.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Successful exploitation grants an attacker complete control over the affected MiniDVBLinux device. The potential consequences include theft or modification of sensitive data, complete service disruption, installation of malware or ransomware, and using the compromised device as a pivot point to launch further attacks against the internal network. The lack of authentication required for exploitation significantly increases the risk, as any attacker with network access to the device can exploit it.

Remediation Plan

Immediate Action: The primary remediation is to apply the security patches provided by the vendor. System administrators should immediately update all instances of MiniDVBLinux Multiple Products to the latest version. Refer to the official vendor security advisory for specific patch information and installation instructions.

Proactive Monitoring: Security teams should actively monitor web server access logs for any requests to the /tpl/commands.sh endpoint. Specifically, look for suspicious or unexpected commands (e.g., wget, curl, nc, bash) within the 'command' GET parameter. Monitor for unusual outbound network traffic from affected devices and any unexpected processes running with root privileges.

Compensating Controls: If immediate patching is not feasible, implement the following controls to mitigate risk:

• Restrict network access to the device's web management interface to a limited set of trusted IP addresses.
• Deploy a Web Application Firewall (WAF) with rules to inspect and block malicious requests targeting the /tpl/commands.sh endpoint.

Exploitation Status

Public Exploit Available: true

Analyst Notes: As of Dec 30, 2025, this vulnerability is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog. However, given the simplicity of the exploit (a single crafted GET request), proof-of-concept code is widely available, and it is highly likely that this vulnerability is being actively scanned for and exploited by threat actors.

Analyst Recommendation

Due to the critical CVSS score of 9.8 and the unauthenticated, remote nature of this vulnerability, immediate remediation is strongly recommended. Organizations must prioritize patching all affected MiniDVBLinux devices without delay. If patching cannot be performed immediately, the compensating controls listed above should be implemented as an urgent temporary measure. The high potential for complete system compromise makes this a top-priority security issue.
