The remote FortiGate device is running a version of FortiOS that is 5.2.x prior to 5.2.10, or else it is running version 5.4.1. It is, therefore, affected by a local information disclosure vulnerability due to a failure to properly protect password hashes stored on the device. A local attacker can exploit this to obtain password hashes of other users on the device, allowing the attacker to possibly obtain user passwords, including the passwords of super-admin users.
