CVE-2026-5709

Estado: AnalizadaAlta (7.7)—

Unsanitized input in the FileBrowser API in AWS Research and Engineering Studio (RES) version 2024.10 through 2025.12.01 might allow a remote authenticated actor to execute arbitrary commands on the cluster-manager EC2 instance via crafted input when using the FileBrowser functionality.

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.

Vulnerabilidad de inyección de comandos (CWE-78) en API remota que requiere autenticación (PR:L) en servicio AWS sin UI interactiva; ejecución de código arbitrario en instancia EC2.

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.
