Description: Two seperate instances of unquoted service path privilege escalation has been discovered. The first instance is within Wise Care 365 4.27 which installs a vulnerable service entitled WiseBootAssistant. The second vulnerability exists when Wise Disk Cleaner 9.29 installs SpyHunter 4. Both of these services run with SYSTEM privileges. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. 2.

If successful, the local user's code would execute with the elevated privileges of the application.
