Estado: AnalizadaMedia (5.3)⚠ Explotación activa

An XSS issue was discovered in

MDaemon Email Server before version 24.5.1c. An attacker can send an HTML e-mail message with JavaScript in an img tag. This could allow a remote attacker

to load arbitrary JavaScript code in the context of a webmail user's browser window.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

XSS en webmail MDaemon (CWE-79) mediante img tag con JavaScript, ejecutable en navegador del usuario (UI:P). Permite inyección de código JavaScript (T1059.007) y acceso a datos/sesiones del usuario (T1005, T1078).

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.
