CVE-2026-58452
JAIOTlink C492A-W6 Wi-Fi IP cameras running firmware 4.8.30.57701411 contain an OS command injection vulnerability that allows authenticated attackers to achieve remote code execution by supplying a malicious Wireless parameter to the HTTP PUT NetSDK/Factory SetMAC endpoint. Attackers can craft a string beginning with a valid MAC-like prefix followed by a semicolon and a shell payload, which bypasses partial sscanf() validation and is passed unsanitized into an echo shell command executed through a system() wrapper.
