What is CVE-2016-9879?

A vulnerability exists in Pivotal Spring Security where URL path parameters are not considered when enforcing security constraints. This issue can lead to security bypasses when an attacker strategically includes an encoded '/' in the request. The problem is rooted in the inconsistencies in the handling of path parameters across different Servlet containers, particularly how they return values for getPathInfo(). Notably, users of Apache Tomcat are safeguarded since it adheres to established guidelines by stripping path parameters, whereas users of IBM WebSphere Application Server 8.5.x and other unverified containers may be at risk.
