Unauthenticated Command Injection in AVTECH DVR Search.cgi
CVE-2025-34054 is an unauthenticated OS command injection vulnerability in AVTECH DVR devices. The issue is exposed through the CGI endpoint Search.cgi when invoked with action=cgi_query. According to the provided content, the vulnerable code path uses wget with attacker-controlled input and does not properly sanitize that input before passing it to the shell. An attacker can inject arbitrary shell metacharacters through the username or queryb64str parameters, causing unintended command execution on the device. Successful exploitation results in execution of attacker-supplied commands as root.
