NVD Description

Note: Versions mentioned in the description apply only to the upstream libspring-java package and not the libspring-java package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

Spring Security (Spring Security 4.1.x before 4.1.5, 4.2.x before 4.2.4, and 5.0.x before 5.0.1; and Spring Framework 4.3.x before 4.3.14 and 5.0.x before 5.0.3) does not consider URL path parameters when processing security constraints. By adding a URL path parameter with special encodings, an attacker may be able to bypass a security constraint. The root cause of this issue is a lack of clarity regarding the handling of path parameters in the Servlet Specification. Some Servlet containers include path parameters in the value returned for getPathInfo() and some do not. Spring Security uses the value returned by getPathInfo() as part of the process of mapping requests to security constraints. In this particular attack, different character encodings used in path parameters allows secured Spring MVC static resource URLs to be bypassed.
