CVE-2022-23447Network attack vector

Unauthenticated file disclosure via crafted pathnames

Published Jul 11, 2023 · Updated Oct 23, 2024

Path traversal in the Fortinet FortiExtender management interface allows remote attackers to read arbitrary filesystem files. The interface accepts crafted web-request pathnames without confining file resolution to the intended directory. No authentication or user interaction is required, and the documented impact is read-only disclosure from the appliance filesystem.
