CVE-2026-11879

Estado: AplazadaAlta (8.5)—

MobaXterm Personal Edition (Portable), in its 26.3 version (Build 5154), allows arbitrary code execution by loading malicious DLLs from a temporary directory that is predictable and can be modified by the user. During startup, the application searches for specific DLLs in this location before resorting to the system’s secure paths, enabling an attacker with local access to place a specially crafted DLL to be executed automatically when the victim launches the application.

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 sin UI requiere acceso local con privilegios limitados (T1068). El DLL hijacking predecible (CWE-427) desde directorio temporal permite ejecución de código arbitrario (T1059) vía secuestro de dependencias (T1574.007).

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.
