CVE-2024-31491Network attack vector

Configuration disclosure and modification via client-side controls

Published May 14, 2024 · Updated Jan 14, 2026

Authorization bypass in Fortinet FortiSandbox 4.2.1 through 4.2.6 and 4.4.0 through 4.4.4 allows remote authenticated users to alter configuration. The HTTP management interface relies on client-side controls instead of enforcing the read-only role when processing configuration upload and download requests. At least read-only permission is required; exploitation exposes device configuration and allows unauthorized replacement of it.
