Finding 1: Plaintext storage of PureVPN Windows Client Credentials Credit: Manuel Nader of Trustwave CVE: CVE-2018-18656 The PureVPN Windows Client stores the Login Credentials (username and password) in plaintext. The location of the file is: 'C:\ProgramData\purevpn\config\login.conf' Additionally, such file has can be read by all local users in a multiuser environment. Finding 2: Local attacker may obtain another user's PureVPN Credentials Credit: Manuel Nader of Trustwave The PureVPN Windows Client provided by PureVPN may allow a local attacker to retrieve the stored password of the last user who successfully logged in to the PureVPN service. A local attacker may obtain another user's PureVPN credentials when a Windows machine has multiple users, if they have successfully logged in. The attack is done exclusively through the GUI (Graphical User Interface), there's no need to use an external tool. Steps to obtain the password: 1. Open the PureVPN Windows Client. 2. Go to Configuration 3. Open the "User Profile" tab 4. Click on "Show Password" Remediation Steps: Upgrade to the latest stable version of PureVPN. Please note that Trustwave confirmed PureVPN mitigated plaintext password storage in version 6.1.0. The vender has accepted the risks of the password being revealed in the client's configuration window. Additionally, it is recommended to never re-use passwords and enable two-factor authentication when possible.
