Descriptions
NETGEAR R7800 net-cgi Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R7800 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of the soap_block_table file. 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 data structure. An attacker can leverage this vulnerability to execute code in the context of root.
. Was ZDI-CAN-13055.
Vulnerabilidad de ejecución remota de código de escritura fuera de los límites en NETGEAR R7800 net-cgi. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de enrutadores NETGEAR R7800. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe en el análisis del archivo Soap_block_table. 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 una estructura de datos asignada. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-13055.
