CVE-2023-27998Network attack vector

Sensitive information disclosure via default error pages

Published Sep 13, 2023 · Updated Sep 25, 2024

Information disclosure in Fortinet FortiPresence 1.0.0 through 1.2.1 allows remote attackers to read sensitive data via crafted HTTPS paths. The login GUI returns default platform error pages instead of custom errors for specific paths, exposing details contained in those responses. No authentication or user interaction is required, but the login GUI must be reachable; published records do not identify the paths or disclosed fields.
