The version of FortiWeb installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-22-254 advisory.

  • A improper neutralization of special elements used in an os command (‘os command injection’) in Fortinet FortiWeb version 7.0.0 through 7.0.2, FortiWeb version 6.3.6 through 6.3.20, FortiWeb 6.4 all versions allows attacker to execute unauthorized code or commands via specifically crafted HTTP requests.
    (CVE-2022-39951)

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