low Nessus Plugin ID 165242

Language:

Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-22-158 advisory.

 - A missing cryptographic steps vulnerability [CWE-325] in the functions that encrypt the keytab files in FortiOS version 7.2.0, 7.0.0 through 7.0.5 and below 7.0.0 may allow an attacker in possession of the encrypted file to decipher it. (CVE-2022-29053)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Please upgrade to FortiOS version 7.0.6/7.2.1 or later.
