Missing Authorization


Severity High
Score 8.8/10


A privilege escalation vulnerability exists in the WinRing0x64 Driver Privileged I/O Write IRPs functionality of NZXT CAM 4.8.0. A specially crafted I/O request packet (IRP) can cause increased privileges. Using the IRP 0x9c40a0dc gives a low privilege user direct access to the OUT instruction that is completely unrestrained at an elevated privilege level. An attacker can send a malicious IRP to trigger this vulnerability.
