The CorsairService Service in Corsair Utility Engine is installed with insecure default permissions, which allows unprivileged local users to execute arbitrary commands via modification of the CorsairService BINARY_PATH_NAME, leading to complete control of the affected system. The issue exists due to the Windows "Everyone" group being granted SERVICE_ALL_ACCESS permissions to the CorsairService Service.

The "CLink4Service" service is installed with Corsair Link 4.9.7.35 with insecure permissions by default. This allows unprivileged users to take control of the service and execute commands in the context of NT AUTHORITY\SYSTEM, leading to total system takeover, a similar issue to CVE-2018-12441.

The CorsairLLAccess64.sys and CorsairLLAccess32.sys drivers in CORSAIR iCUE before 3.25.60 allow local non-privileged users (including low-integrity level processes) to read and write to arbitrary physical memory locations, and consequently gain NT AUTHORITY\SYSTEM privileges, via a function call such as MmMapIoSpace.

Missing AES encryption in Corsair K63 Wireless 3.1.3 allows physically proximate attackers to inject and sniff keystrokes via 2.4 GHz radio transmissions.
