CVE-2022-23442Network attack vector

Restricted-user VDOM checksum disclosure

Published Aug 3, 2022 · Updated Oct 22, 2024

Improper access control in Fortinet FortiOS 6.2.0 through 7.0.5 allows remote authenticated users to gather other VDOM checksums via CLI commands. Restricted CLI profiles can invoke checksum queries without isolation from other VDOMs, exposing integrity-related metadata across virtual domains. Access requires a valid restricted account; the documented impact is limited information disclosure, with no reported configuration change or service interruption.
