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.

Summary		(es) Las cámaras IP Wi-Fi JAIOTlink C492A-W6 que ejecutan el firmware 4.8.30.57701411 contienen una vulnerabilidad de inyección de comandos del sistema operativo que permite a atacantes autenticados lograr la ejecución remota de código al proporcionar un parámetro Wireless malicioso al endpoint HTTP PUT NetSDK/Factory SetMAC. Los atacantes pueden crear una cadena que comienza con un prefijo válido similar a una MAC seguida de un punto y coma y una carga útil de shell, lo que omite la validación parcial de sscanf() y se pasa sin sanitizar a un comando de shell echo ejecutado a través de un wrapper de system().
