CVE-2020-13514 — A privilege escalation vulnerability exists in the WinRing0x64 Driver Privileged I/O Write IRPs functionality of NZXT CAM 4.8.0

High CVSS 8.8

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 0x9c40a0e0 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.

Matched remediation archetype

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
