CVE-2026-15637

Estado: AnalizadaAlta (7.5)—

Improper authorization in the PAM SSH key and certificate retrieval endpoints in Devolutions Server 2026.2.11, 2026.1.22 allows an authenticated low-privileged user to disclose the private key of an SSH key or certificate PAM credential via a direct object reference to the credential identifier.

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:N sin UI permite acceso remoto sin privilegios (T1190). Un usuario autenticado accede a claves privadas SSH via IDOR (CWE-639), revelando credenciales almacenadas (T1552.007) que podrían usarse para acceso lateral (T1078.001).

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.
