Vulnerability description:

Wondershare Dr Fone version 12.9.6 running services named “WsDrvInst” on
Windows have weak service permissions and are susceptible to local
privilege escalation vulnerability. Weak service permissions run with
system user permission, allowing a standard user/domain user to elevate to

permission to any authenticated users in the windows operating system,
allowing standard users to modify the service and leading to Privilege
Escalation.
