CVE-2012-5409 Information

Description

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.
