CVE-2026-5708

Estado: AnalizadaAlta (8.7)—

Unsanitized control of user-modifiable attributes in the session creation component in AWS Research and Engineering Studio (RES) prior to version 2026.03 could allow an authenticated remote user to escalate privileges, assume the virtual desktop host instance profile permissions, and interact with AWS resources and services via a crafted API request.

To remediate this issue, users are advised to upgrade to RES version 2026.03 or apply the corresponding mitigation patch to their existing environment.

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 con AV:N/PR:L/UI:N indica red con autenticación previa sin interacción. Descripción explícita de escalada de privilegios y asunción de credenciales de rol de instancia (AssumeRole).

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.
