1. 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.

3. Exploit:
|
|
|
|
A successful attempt would require the local user to be able to insert their
|
|
code in the system root path undetected by the OS or other security applications
|
|
where it could potentially be executed during application startup or reboot.
|
|
If successful, the local user's code would execute with the elevated privileges
|
|
of the application. |
