CVE-2018-6683

Status: ModifiedHigh (7.4)—

Exploiting Incorrectly Configured Access Control Security Levels vulnerability in McAfee Data Loss Prevention (DLP) for Windows versions prior to 10.0.505 and 11.0.405 allows local users to bypass DLP policy via editing of local policy files when offline.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
