Multiple system services installed alongside the Razer Synapse 3 software suite perform privileged operations on entries within the Razer Chroma SDK subkey. These privileged operations consist of file name concatenation of a runtime log file that is used to store runtime log information. In other words, an attacker can create a file in an unintended directory (with some limitations).
Razer Chroma SDK Rest Server through 3.12.17 allows remote attackers to execute arbitrary programs because there is a race condition in which a file created under "%PROGRAMDATA%\Razer Chroma\SDK\Apps" can be replaced before it is executed by the server. The attacker must have access to port 54236 for a registration step.
The RzSurroundVADStreamingService (RzSurroundVADStreamingService.exe) in Razer Surround 1.1.63.0 runs as the SYSTEM user using an executable located in %PROGRAMDATA%\Razer\Synapse\Devices\Razer Surround\Driver\. The DACL on this folder allows any user to overwrite contents of files in this folder, resulting in Elevation of Privilege.
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.
