Fortinet FortiOS < 5.6.11 / 6.0.0 < 6.0.7 / 6.2.0 < 6.2.2 Information Disclosure (FG-IR-19-134)

medium Nessus Plugin ID 131185
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
