Pre-authentication arbitrary file read vulnerability (CVE-2019-11510) that revealed sensitive information like VPN client credentials, private SSH keys, and session cookies. They showed how this information was used to compromise a client session and gain access to a VPN network, then demonstrated additional post-authentication exploits that resulted in complete takeover of the VPN server. In order to exploit the issue, an attacker can send a malicious HTTP request containing directory traversal sequences along with a crafted Uniform Resource Identifier (URI) and access any file on the device.
