Reachability Analysis

The vulnerable code is unreachable

Vulnerability Details

A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded cookie names.

The ASP.NET Core cookie parser decodes entire cookie strings which could allow a malicious attacker to set a second cookie with the name being percent encoded.

The security update addresses the vulnerability by fixing the way the ASP.NET Core cookie parser handles encoded names.
