CVE-2018-0886

Status: ModifiedHigh (7)—💥 Exploit

The Credential Security Support Provider protocol (CredSSP) in Microsoft Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1 and RT 8.1, Windows Server 2012 and R2, Windows 10 Gold, 1511, 1607, 1703, and 1709 Windows Server 2016 and Windows Server, version 1709 allows a remote code execution vulnerability due to how CredSSP validates request during the authentication process, aka "CredSSP Remote Code Execution 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.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
