CVE-2026-82971: Command Injection in QVidium Opera11

This vulnerability in QVidium Opera11 3.3.2a26-Ax4x-opera11 involves command injection via the ipaddr argument in the /cgi-bin/net_tr.cgi CGI script. The flaw allows unauthenticated remote attackers to execute arbitrary commands on the affected system. The vendor has discontinued support and sales, leaving no official remediation available. The vulnerability has a CVSS 4.0 base score of 10.0, indicating critical severity. Public exploit code exists, but no known in-the-wild exploitation has been reported.

Successful exploitation could lead to full remote code execution on the affected system without authentication, compromising confidentiality, integrity, and availability. Since the vendor no longer supports the product, affected systems remain vulnerable indefinitely unless mitigated by other means.

No official patch or fix is available because the vendor has ceased support and product sales. Organizations should consider isolating or decommissioning affected systems to prevent exploitation. Alternative mitigations may include network-level access restrictions or disabling the vulnerable CGI script if feasible. Monitor for any signs of exploitation due to public availability of exploit code.
