Attack-Flow Graph

Executive Summary

This vulnerability is a command injection flaw in QVidium Opera11 3.3.2a26-Ax4x-opera11. It exists in the /cgi-bin/net_tr.cgi CGI script where the ipaddr argument can be manipulated to execute arbitrary commands remotely. The vendor has discontinued the product and no longer provides support.

Detection Guidance

Since QVidium Opera11 is no longer supported and the vendor has closed, detection may be difficult. Check if the affected CGI script /cgi-bin/net_tr.cgi exists on your system. If present, inspect for command injection attempts in logs or unusual network traffic targeting this endpoint.

Impact Analysis

Since this is a remote command injection vulnerability with a CVSS v3.1 score of 10.0, it allows attackers to execute arbitrary commands on the affected system. This could lead to full system compromise, data theft, or unauthorized access. However, the product is no longer supported, so patches are unavailable.

Compliance Impact

This vulnerability allows remote command injection via the ipaddr parameter in the CGI script, which could lead to unauthorized access and data breaches. For GDPR, this could result in unauthorized processing of personal data, violating principles of lawfulness and security. For HIPAA, it may compromise protected health information integrity and confidentiality if exploited.

Mitigation Strategies

Since QVidium Opera11 is no longer supported and the vendor has closed, immediate mitigation involves isolating or removing the affected system from the network. Patch or update is not available. Monitor network traffic for signs of exploitation targeting /cgi-bin/net_tr.cgi with command injection attempts.
