This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
A command injection vulnerability was found in the PPTP VPN Clients on the ADM. The vulnerability allows an administrative user to break out of the restricted web environment and execute arbitrary code on the underlying operating system.
