CVE-2021-37364

Description

OpenClinic GA 5.194.18 is affected by Insecure Permissions. By default the Authenticated Users group has the modify permission to openclinic folders/files. A low privilege account is able to rename mysqld.exe or tomcat8.exe files located in bin folders and replace with a malicious file that would connect back to an attacking computer giving system level privileges (nt authority\system) due to the service running as Local System. While a low privilege user is unable to restart the service through the application, a restart of the computer triggers the execution of the malicious file. The application also have unquoted service path issues.
