Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in applications serving static resources through the functional web frameworks WebMvc.fn or WebFlux.fn. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.

Specifically, an application is vulnerable when both of the following are true:

• the web application uses RouterFunctions</code> to serve static resources</li><li>resource handling is explicitly configured with a <code>FileSystemResource location

Mitigation
Install update from vendor's website.
