QID 982719

QID 982719: Java (maven) Security Update for io.vertx:vertx-web (GHSA-9q69-g5gc-9fgf)

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.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
