CVE-2012-5409

Estado: ModificadaAlta (10)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
