CRITICAL: 'MiniPlasma' Windows 0-Day Resurrects 2020 SYSTEM Escalation Bug Microsoft Thought It Killed
A working zero-day exploit dubbed MiniPlasma escalates standard users to SYSTEM on fully patched Windows 11. It abuses cldflt.sys, the same Cloud Filter driver behind CVE-2020-17103 that Microsoft 'fixed' in 2020. PoC is public on GitHub. No patch yet. Assume compromise paths exist on every Windows endpoint until the next Patch Tuesday.
