CVE-2026-74845

Estado: AplazadaAlta (8.7)—

Official Document Management System developed by 2100 Technology has an Arbitrary File Upload vulnerability, allowing authenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.

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:N/PR:L sin UI permite acceso remoto autenticado a servicio vulnerable (T1210). Upload arbitrario ejecutable = web shell (T1505.003) y ejecución de código (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.
