Estado: AnalizadaCrítica (9.3)—

Hyland Alfresco Transformation Service allows unauthenticated attackers to achieve remote code execution through the argument injection vulnerability, which exists in the document processing functionality.

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 CVSS AV:N/PR:N/UI:N indica red sin autenticación (T1190). CWE-918 (SSRF) y RCE mediante inyección de argumentos en servicio de transformación expuesto. T1059 por ejecución remota de código; T1090 secundario por SSRF potencial en flujo de procesamiento.

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.
