Descriptions

Sonos Era 100 SMB2 Message Handling Integer Underflow Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Sonos Era 100 smart speakers. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the handling of SMB2 messages. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before reading from memory. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-22336.

Vulnerabilidad de divulgación de información de desbordamiento de enteros en el manejo de mensajes de Sonos Era 100 SMB2. Esta vulnerabilidad permite a atacantes adyacentes a la red revelar información confidencial sobre las instalaciones afectadas de los altavoces inteligentes Sonos Era 100. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe en el manejo de mensajes SMB2. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un desbordamiento insuficiente de enteros antes de leerlos de la memoria. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar código arbitrario en el contexto de la raíz. Era ZDI-CAN-22336.
