CVE-2020-8950

Status: ModifiedHigh (7.8)—💥 PoC

The AUEPLauncher service in Radeon AMD User Experience Program Launcher through 1.0.0.1 on Windows allows elevation of privilege by placing a crafted file in %PROGRAMDATA%\AMD\PPC\upload and then creating a symbolic link in %PROGRAMDATA%\AMD\PPC\temp that points to an arbitrary folder with an arbitrary file name.

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.
