Administrative cookie decryption via improper signature verification
Published Feb 16, 2023 · Updated Oct 22, 2024
Improper signature verification in affected Fortinet products allows attackers to decrypt parts of an intercepted administrative session cookie. Fortinet has not disclosed which cookie-signature verification routine fails or how the cryptographic check is performed incorrectly. Exploitation requires access to an administrator's cookie in transit, and the published impact is limited to partial confidentiality loss.
