Estado: ModificadaAlta (9.3)—💥 Exploit

Microsoft Windows 2000 Gold through SP4, XP Gold through SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote SMB servers to execute arbitrary code on a client machine by replaying the NTLM credentials of a client user, as demonstrated by backrush, aka "SMB Credential Reflection Vulnerability." NOTE: some reliable sources report that this vulnerability exists because of an insufficient fix for CVE-2000-0834.

CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Puntuación base: 9.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 59%
Percentil entre todas las CVEs puntuadas: 99
Fecha de la puntuación: 7/10/2026

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.
