CVE-2009-0079

Estado: ModificadaMedia (6.9)—💥 Exploit

The RPCSS service in Microsoft Windows XP SP2 and SP3 and Server 2003 SP1 and SP2 does not properly implement isolation among a set of distinct processes that (1) all run under the NetworkService account or (2) all run under the LocalService account, which allows local users to gain privileges by accessing the resources of one of the processes, aka "Windows RPCSS Service Isolation Vulnerability."

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
