CVE-2026-18279

Sony XAV-9500ES RTSP SETUP Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Sony XAV-9500ES devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SETUP RTSP packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29042.

Summary		(es) Vulnerabilidad de desbordamiento de búfer con ejecución remota de código (RCE) en el SETUP RTSP de Sony XAV-9500ES. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de dispositivos Sony XAV-9500ES. No se requiere autenticación para explotar esta vulnerabilidad. El fallo específico existe en el manejo de los paquetes SETUP RTSP. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un búfer de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del dispositivo. Fue ZDI-CAN-29042.
