CVE-2023-36551Network attack vector

Authenticated path disclosure via crafted HTTP request

Published Sep 13, 2023 · Updated Sep 24, 2024

Information disclosure in Fortinet FortiSIEM 6.7.0 through 6.7.5 allows remote authenticated users to obtain supervisor file paths. A crafted HTTP request causes the application to return absolute paths for files used by the supervisor; Fortinet has not disclosed the affected endpoint or faulty operation. Valid credentials are required, and the disclosed paths can supply environmental details useful when chaining other vulnerabilities.
