Exposure of Resource to Wrong Sphere
spring-boot versions prior to version v2.2.11.RELEASE was vulnerable to temporary directory hijacking. This vulnerability impacted the `org.springframework.boot.web.server.AbstractConfigurableWebServerFactory.createTempDir` method. NOTE: This vulnerability only affects products and/or versions that are no longer supported by the maintainer.

Spring Boot EndpointRequest.to() creates wrong matcher if actuator endpoint is not exposed
EndpointRequest.to() creates a matcher for null/** if the actuator endpoint, for which the EndpointRequest has been created, is disabled or not exposed.

Your application may be affected by this if all the following conditions are met:

  *  You use Spring Security
  *  EndpointRequest.to() has been used in a Spring Security chain configuration
  *  The endpoint which EndpointRequest references is disabled or not exposed via web
  *  Your application handles requests to /null and this path needs protection


You are not affected if any of the following is true:

  *  You don't use Spring Security
  *  You don't use EndpointRequest.to()
  *  The endpoint which EndpointRequest.to() refers to is enabled and is exposed
  *  Your application does not handle requests to /null or this path does not need protection

Spring Boot Actuator denial of service vulnerability
In Spring Boot versions 2.7.0 - 2.7.17, 3.0.0-3.0.12 and 3.1.0-3.1.5, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.

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

*  the application uses Spring MVC or Spring WebFlux
*  `org.springframework.boot:spring-boot-actuator` is on the classpath

Symlink privilege escalation attack via Spring Boot launch script
Spring Boot supports an embedded launch script that can be used to easily run the application as a systemd or init.d linux service. The script included with Spring Boot is susceptible to a symlink attack which allows the `run_user` to overwrite and take ownership of any file on the same system. In order to instigate the attack, the application must be installed as a service and the `run_user` requires shell access to the server.
