CSRF bypass via attacker-chosen matching tokens
Published Jan 20, 2021 · Updated Sep 16, 2024
CSRF in SoftwareMill akka-http-session allows remote attackers to bypass request-origin checks with forged matching tokens. The randomTokenCsrfProtection directive accepts any nonempty X-XSRF-TOKEN header and XSRF-TOKEN cookie when their attacker-chosen values match, without verifying server provenance. Exploitation requires a cookie-based application to invoke the directive on a state-changing route and a victim to submit the forged request; resulting actions run with the victim's session privileges.
