An incorrect privilege assignment vulnerability exists in Esri Portal for ArcGIS 11.5 in Windows and Linux that allows highly privileged users to create developer credentials that may grant more privileges than expected.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.2

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.47%
Percentil entre todas las CVEs puntuadas: 38
Fecha de la puntuación: 6/10/2026

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.

Impacto secundarioT1078.004 Cloud Accountsstealth · persistence · privilege escalation · initial access75 %

AV:N + PR:H sugiere acceso remoto con altos privilegios (T1210). El atacante crea credenciales de desarrollador con privilegios excesivos (T1098.002: Account Manipulation, creación de cuentas con permisos elevados), escalando autorización (T1078.004).

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.
