CVE-2018-14773  (opens in a new tab)
CWE-284  (opens in a new tab)

How to fix?

Upgrade symfony/http-foundation to versions 2.7.49, 2.8.44, 3.3.18, 3.4.14, 4.0.14, 4.1.3 or higher

Overview

symfony/http-foundation is a set of reusable PHP components.

Affected versions of this package are vulnerable to Access Restriction Bypass. It maintained support for (legacy) IIS headers (X-Original-URL or X-Rewrite-URL) that allowed users to override the path in a request URL. As a result, it allowed a user to access one URL but have Symfony return a different one which can bypass restrictions on higher level caches and web servers.
