However, the resulting server file was digitally signed via a base-64 encoded signature appearing on the bottom of the file. This call was done over HTTP without the use of SSL / TLS. While monitoring network traffic of a test device running Android, we observed that the official PIA Android client application downloaded from the Google Play store made network calls to a PIA server to retrieve a list of current VPN servers in JSON format. PIA provides official clients for multiple operating systems including Windows, Chrome, macOS, Linux, iOS and Android. The vendor provides a privacy service to encrypt Internet connections via VPN tunnels and have them terminate on anonymous IP addresses. Private Internet Access (PIA) is a commercial VPN service operated by London Trust Media, Inc. MITRE has assigned # CVE-2017-15882 to track this issue. The vendor has fixed this issue in v1.3.3.1 and users should install the latest version. While the file is digitally signed, it is not served over SSL and the application did not contain logic for checking if the provided file is very large. This can be exploited by an MITM attacker via intercepting and replacing this file. I will also try posting on the PIA forums.The Android application provided by Private Internet Access (PIA) VPN service can be crashed by downloading a large file containing a list of current VPN servers. I have spent many hours on this now with no progress being made. The TAP driver files appear to be getting copied to the system 32 and driver store folders, but windows is not "registering" the driver properly. None of these however have solved the problem.

I also tried installing several versions of openVPN including: I tried installing several versions of TAP windows (the latest being tap-windows-9.21.2), however I keep getting a failure when trying to install the TAP driver. I uninstalled PIA v80, made sure the driver and driver store was clear then did some research on the forums were I learned some people solved this problem by installing TAP windows before PIA. When trying to connect to a VPN server I received the dreaded error message about the TAP driver needing to be reinstalled. Shortly after this issue began I started receiving a message that there was a new version of the VPN client (v80) available, previously I was using v65. However, about a week ago the PIA VPN client started randomly disconnecting a few minutes after connecting to any server. I have been using the VPN client for over a year without any problems. I have Windows 7 pro 64 bit and the Private Internet Access VPN client installed on my home PC. ![]()
