Descriptions
In Spring Boot versions 3.0.0 - 3.0.6, 2.7.0 - 2.7.11, 2.6.0 - 2.6.14, 2.5.0 - 2.5.14 and older unsupported versions, there is potential for a denial-of-service (DoS) attack if Spring MVC is used together with a reverse proxy cache.
A flaw was found in Spring Boot, occurring prominently in Spring MVC with a reverse proxy cache. This issue requires Spring MVC to have auto-configuration enabled and the application to use Spring Boot's welcome page support, either static or templated, resulting in the application being deployed behind a proxy that caches 404 responses. This issue may cause a denial of service (DoS) attack.
