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-22-251 advisory.

  • A relative path traversal 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 information disclosure via specially crafted web requests. (CVE-2023-23784)

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