# Exploit Title: Wondershare Dr Fone 12.9.6 - Privilege Escalation # Date: 14 March 2023 # Exploit Author: Thurein Soe # Vendor Homepage: https://drfone.wondershare.com # Software Link: https://mega.nz/file/ZFd1TZIR#e2WfCX_ryaH08C3VNGZH1yAIG6DU01p-M_rDooq529I # Version: Dr Fone version 12.9.6 # Tested on: Window 10 (10.0.19045.2604) # CVE : CVE-2023-27010 *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 administrator privilege upon successfully modifying the service or replacing the affected executable. DriverInstall.exe gave modification permission to any authenticated users in the windows operating system, allowing standard users to modify the service and leading to Privilege Escalation.
