CVE-2023-32154

Estado: AnalizadaAlta (7.5)—

Mikrotik RouterOS RADVD Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Mikrotik RouterOS. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the Router Advertisement Daemon. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-19797.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de Mikrotik RouterOS. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro del demonio de publicidad del enrutador. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-19797."
