Descriptions

AscoServer.exe in the server in Siemens SiPass integrated MP2.6 and earlier does not properly handle IOCP RPC messages received over an Ethernet network, which allows remote attackers to write data to any memory location and consequently execute arbitrary code via crafted messages, as demonstrated by an arbitrary pointer dereference attack or a buffer overflow attack.

AscoServer.exe en el servidor en Siemens SiPass integrated MP2.6 y anteriores no trata correctamente los mensajes RPC IOCP recibidos a través de una red Ethernet, lo que permite a atacantes remotos escribir datos en cualquier posición de memoria y por lo tanto ejecutar código de su elección a través de mensajes modificados a mano, tal y como se ha demostrado por un ataque de desreferencia de un puntero de su elección o un ataque de desbordamiento de búfer.
