CVE-2018-0743

Status: ModifiedHigh (7)—💥 Exploit

Windows Subsystem for Linux in Windows 10 version 1703, Windows 10 version 1709, and Windows Server, version 1709 allows an elevation of privilege vulnerability due to the way objects are handled in memory, aka "Windows Subsystem for Linux Elevation of Privilege Vulnerability".

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
