CVE-2025-34423

Estado: AnalizadaAlta (8.5)—

MailEnable versions prior to 10.54 contain an unsafe DLL loading vulnerability that can lead to local arbitrary code execution. The MailEnable administrative executable attempts to load MEAIAU.DLL from its installation directory without sufficient integrity validation or a secure search order. A local attacker with write access to that directory can plant a malicious MEAIAU.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.

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.

Vector AV:L/PR:L sin UI indica acceso local con privilegios limitados. CWE-427 (carga insegura de DLL) y la descripción de plantación de DLL malicioso en directorio de instalación confirman T1068 (escalada mediante hijacking de búsqueda). T1574.007 (DLL Search Order Hijacking) es el mecanismo; T1059

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.
