CVE-2025-34489

Estado: ModificadaAlta (7.8)—

GFI MailEssentials prior to version 21.8 is vulnerable to a local privilege escalation issue. A local attacker can escalate to NT Authority/SYSTEM by sending a crafted serialized payload to a .NET Remoting Service.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L, PR:L, UI:N indica escalada local sin interacción (T1068). La serialización deserialized (CWE-502) en .NET Remoting permite ejecutar comandos con privilegios SYSTEM.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
