Descriptions

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Sonos One Speaker prior to 3.4.1 (S2 systems) and 11.2.13 build 57923290 (S1 systems). Authentication is not required to exploit this vulnerability. The specific flaw exists within the anacapd daemon. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15828.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de Sonos One Speaker versiones anteriores a 3.4.1 (sistemas S2) y 11.2.13 build 57923290 (sistemas S1). No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta en el demonio anacapd. El problema es debido a que no es comprobado apropiadamente los datos suministrados por el usuario, lo que puede resultar en un desbordamiento de enteros antes de escribir en la memoria. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de root. Era ZDI-CAN-15828
