medium Nessus Plugin ID 131185

Language:

Synopsis

The remote host is affected by an information disclosure vulnerability.

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's encryption password for builtin system certificates or setting a blank password for user uploaded certificates. The attacker can use this to disclose plaintext private keys.

Solution

Upgrade to Fortinet FortiOS version to 5.6.11, 6.0.9, 6.2.2 or later.
