Medium (5.9). EPSS 30% chance of exploitation in the next 30 days. Fixed in org.springframework:spring-core 4.3.15, 5.0.5.
Spring Framework, versions 5.0 prior to 5.0.5 and versions 4.3 prior to 4.3.15 and older unsupported versions, allow applications to configure Spring MVC to serve static resources (e.g. CSS, JS, images). When static resources are served from a file system on Windows (as opposed to the classpath, or the ServletContext), a malicious user can send a request using a specially crafted URL that can lead a directory traversal attack.
