Estado: AnalizadaAlta (7.5)⚠ Explotación activa

SysAid On-Prem versions <= 23.3.40 are vulnerable to an unauthenticated XML External Entity (XXE) vulnerability in the Checkin processing functionality, allowing for administrator account takeover and file read primitives.

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.

XXE en procesamiento Checkin sin autenticación (AV:N, PR:N) permite lectura de archivos y takeover de cuenta admin. Vector CVSS HIGH con C:H confirma exfiltración de datos sensibles.

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.
