CVE-2011-0045

Estado: ModificadaAlta (7.2)—💥 Exploit

The Trace Events functionality in the kernel in Microsoft Windows XP SP3 does not properly perform type conversion, which causes integer truncation and insufficient memory allocation and triggers a buffer overflow, which allows local users to gain privileges via a crafted application, related to WmiTraceMessageVa, aka "Windows Kernel Integer Truncation 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.
