CVE-2014-125028Network attack vector

Forged sign-in via missing OAuth state validation

Published Dec 31, 2022 · Updated Aug 6, 2024

Cross-site request forgery in Valtech IDP Test Clients allows remote attackers to alter a user's sign-in state through an OAuth callback. The Python Flask sign_in flow omits an OAuth state value, and sign_in_callback accepts the returned authorization code without matching it to the initiating browser. Exploitation requires user interaction with an attacker-controlled authorization response and can bind the victim's session to an unintended account.
