Описание
Netty is a network application framework for development of protocol servers and clients. Versions 4.2.0.Final through 4.2.15.Final and 4.1.0.Final through 4.1.135.Final, are vulnerable to security control bypass during the origin evaluation process. CorsHandler provides a shortCircuit() configuration designed to reject unauthorized cross-origin requests immediately, acting as a security control before requests reach the application. However, due to a logical operator error in the origin evaluation process, this protection can be entirely bypassed. An attacker can bypass the short-circuit mechanism by sending a request with an Origin: null header. This failure forwards unauthorized requests to the backend application, bypassing intended access controls. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.
A flaw was found in Netty, a network application framework. A remote attacker can bypass security controls in the CorsHandler component by sending a specially crafted request with a null origin header. This bypasses the intended access restrictions, allowing unauthorized requests to reach the backend application. This could lead to a compromise of data integrity by allowing unauthorized actions.
