CVE-2022-45860Network attack vector

Unauthenticated improper access via weak device registration authentication

Published May 3, 2023 · Updated Oct 23, 2024

Weak authentication in Fortinet FortiNAC 8.7.0 through 9.4.2 allows remote attackers to password-spray the device registration page. Fortinet identifies the GUI registration page but has not disclosed which deficient authentication control increases password-spraying success. No prior authentication or user interaction is required; successful password guesses provide improper access through the registration workflow.
