Cross-request identity substitution via shared authentication module
Published May 4, 2020 · Updated Aug 4, 2024
Improper access control in Red Hat Soteria before 1.0.1 allows remote authenticated users to have requests handled as another identity. The JASPIC integration registers one mutable ServerAuthModule instance and reuses it across concurrent ServerAuthContext operations instead of creating a module per request. Exploitation requires authenticated concurrent requests through EE Security with WildFly Elytron and can expose or modify data under another request's identity.
