CVE-2024-42475Network attack vector

Session misbinding via predictable OAuth state values

Published Aug 15, 2024 · Updated Aug 19, 2024

CSRF in CORDEA oauth before 0.11 allows remote attackers to associate a user's session with attacker-controlled protected resources. The generateState function uses a regular pseudorandom generator with too little entropy instead of a CSPRNG, making OAuth state values guessable. Successful exploitation requires the user to complete an attacker-initiated OAuth flow and exposes the linked protected resources.
