Описание
Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core allows an authorized attacker to bypass a security feature over a network.
A flaw was found in ASP.NET Core’s HTTP request handling that leads to inconsistent interpretation of specially crafted HTTP requests. This mismatch can be abused by an authorized network attacker to smuggle or manipulate request boundaries, allowing bypass of security controls or unintended forwarding of request data.
Отчет
The Red Hat Product Security team has assessed this issue as Important. An authorized network attacker can exploit inconsistent HTTP request parsing in ASP.NET Core to bypass security controls (HTTP request smuggling), potentially exposing or enabling unauthorized actions on request data in affected .NET runtimes.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
