Razer ≫ Synapse

rzpnk.sys in Razer Synapse 2.20.15.1104 allows local users to read and write to arbitrary memory locations, and consequently gain privileges, via a methodology involving a handle to \Device\PhysicalMemory, IOCTL 0x22A064, and ZwMapViewOfSection.

Razer Synapse 2.20.15.1104 and earlier uses weak permissions for the CrashReporter directory, which allows local users to gain privileges via a Trojan horse dbghelp.dll file.

Razer Synapse 2.20.15.1104 and earlier uses weak permissions for the Devices directory, which allows local users to gain privileges via a Trojan horse (1) RazerConfigNative.dll or (2) RazerConfigNativeLOC.dll file.

A specially crafted IOCTL can be issued to the rzpnk.sys driver in Razer Synapse 2.20.15.1104 that is forwarded to ZwOpenProcess allowing a handle to be opened to an arbitrary process.
