HomeGuard Pro 9.3.1 – Insecure Folder Permissions

The HomeGuard Pro version 9.3.1 has insecure folder permissions which allows BUILTINUsers to have full control over the 'C:Program FilesHomeGuard Pro' folder. Additionally, the files and services within the folder also have insecure permissions, allowing BUILTINUsers to have full control over them.

Mitigation:

The vendor should fix the folder and file/service permissions to restrict access only to authorized users. Users should also ensure that they have the latest version of HomeGuard Pro installed to mitigate this vulnerability.
