CVE-2017-3891

Estado: ModificadaCrítica (9.6)—

In BlackBerry QNX Software Development Platform (SDP) 6.6.0, an elevation of privilege vulnerability in the default configuration of the QNX SDP with QNet enabled on networks comprising two or more QNet nodes could allow an attacker to access local and remote files or take ownership of files on other QNX nodes regardless of permissions by executing commands targeting arbitrary nodes from a secondary QNX 6.6.0 QNet node.

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).
