Estado: Pendiente de análisisAlta (8.6)—

There is an improper access control vulnerability in NI SystemLink that may allow an authenticated user with limited privileges to access host operating system files and directories that should be restricted. This vulnerability affects NI SystemLink and NI SystemLink Server versions prior to 2026 Q3.

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 con PR:L indica servicios remotos con autenticación limitada (T1210). VC:H permite leer archivos del SO restringidos (T1005), elevando privilegios de acceso (T1078).

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.
