CVE-2020-13509

Exp

An information disclosure vulnerability exists in the WinRing0x64 Driver Privileged I/O Read IRPs functionality of NZXT CAM 4.8.0. A specially crafted I/O request packet (IRP) Using the IRP 0x9c4060cc gives a low privilege user direct access to the IN instruction that is completely unrestrained at an elevated privilege level. An attacker can send a malicious IRP to trigger this vulnerability and this access could allow for information leakage of sensitive data.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
6.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
