Session fixation via skipped ID token nonce validation
Published Nov 6, 2024 · Updated Nov 6, 2024
Session fixation in F5 NGINX OpenID Connect allows remote attackers to bind a victim's session to an attacker-controlled account. The validateIdToken function uses unreliable global newSession state, causing it to skip the ID token nonce comparison during initial authentication. Exploitation requires victim interaction with a crafted login flow; it exposes the victim's actions within the attacker's account but does not grant access to the victim's account.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
