Detailsinfo

A vulnerability classified as critical was found in Razer Synapse up to 3.7.1209.121307 on Windows. Affected by this vulnerability is an unknown code of the file %PROGRAMDATA%\Razer\Synapse3\Service\bin. The manipulation with an unknown input leads to a privileges assignment vulnerability.

As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Razer Synapse through 3.7.1209.121307 allows privilege escalation due to an unsafe installation path and improper privilege management. Attackers can place DLLs into %PROGRAMDATA%\Razer\Synapse3\Service\bin if they do so before the service is installed and if they deny write access for the SYSTEM user. Although the service will not start if it detects malicious DLLs in this directory, attackers can exploit a race condition and replace a valid DLL (i.e., a copy of a legitimate Razer DLL) with a malicious DLL after the service has already checked the file. As a result, local Windows users can abuse the Razer driver installer to obtain administrative privileges on Windows.
