CVE-2020-35217 (GCVE-0-2020-35217)

Vulnerability from cvelistv5 – Published: 2021-01-20 12:28 – Updated: 2024-08-04 17:02

Summary

Vert.x-Web framework v4.0 milestone 1-4 does not perform a correct CSRF verification. Instead of comparing the CSRF token in the request with the CSRF token in the cookie, it compares the CSRF token in the cookie against a CSRF token that is stored in the session. An attacker does not even need to provide a CSRF token in the request because the framework does not consider it. The cookies are automatically sent by the browser and the verification will always succeed, leading to a successful CSRF attack.
