CVE-2018-11039

Spring Framework (versions 5.0.x prior to 5.0.7, versions 4.3.x prior to 4.3.18, and older unsupported versions) allow web applications to change the HTTP request method to any HTTP method (including TRACE) using the HiddenHttpMethodFilter in Spring MVC. If an application has a pre-existing XSS vulnerability, a malicious user (or attacker) can use this filter to escalate to an XST (Cross Site Tracing) attack.

Mitigation

According to the upstream advisory, this attack applies to applications that allow the application server to handle HTTP TRACE requests, and use the HiddenHttpMethodFilter. Note that in the HiddenHttpMethodFilter is enabled by default in Spring Boot.
