A vulnerability was discovered in Siemens SiPass integrated (All versions before V2.70) that could allow an attacker with local access to the SiPass integrated server or SiPass integrated client to potentially obtain credentials from the systems.
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.
