| description | The remote host is running a version of FortiOS prior to 5.6.11, 6.0.x prior to 6.0.7, or 6.2.x prior to 6.2.2. It is, therefore, affected by an information disclosure vulnerability. The vulnerability exists in the storage of private keys and certificates due to improper value checking or permissions. A non-privileged, local attacker can exploit this via the CLI by unsetting a private key |
