"According to its self-reported version, the version of Pulse Connect Secure running on the remote host is prior to 
8.1R15.1, 8.2.x < 8.2R12.1, 8.3.x < 8.3R7.1 or 9.x prior to 9.0R3.4. It is, therefore, affected by an arbitrary file 
read vulnerability due to insufficient user input validation. An unauthenticated, remote attacker can exploit this, by 
requesting a specially crafted URI, to read arbitrary files and disclose sensitive information.");
