             Summary: Upgrade org.springframework:spring-core for CVE-2022-22965 (a.k.a. Spring4Shell)
                 Key: IGNITE-16781
                 URL: https://issues.apache.org/jira/browse/IGNITE-16781
             Project: Ignite
          Issue Type: Bug
          Components: spring
            Reporter: Danut Radoaica


Upgrade org.springframework:spring-beans to version 5.2.20 or later

Upgrade org.springframework:spring-core to version 5.2.20 or later

Vulnerable versions: < 5.2.20
Patched version: 5.2.20
Spring Framework prior to versions 5.2.20 and 5.3.18 contains a remote code execution vulnerability known as Spring4Shell.

Impact
A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.

These are the prerequisites for the exploit:

JDK 9 or higher
Apache Tomcat as the Servlet container
Packaged as WAR
spring-webmvc or spring-webflux dependency
Patches
Spring Framework 5.3.18 and 5.2.20
Spring Boot 2.6.6 and 2.5.12
Workarounds
For those who are unable to upgrade, leaked reports recommend setting disallowedFields on WebDataBinder through an @ControllerAdvice. This works generally, but as a centrally applied workaround fix, may leave some loopholes, in particular if a controller sets disallowedFields locally through its own @InitBinder method, which overrides the global setting.

To apply the workaround in a more fail-safe way, applications could extend RequestMappingHandlerAdapter to update the WebDataBinder at the end after all other initialization. In order to do that, a Spring Boot application can declare a WebMvcRegistrations bean (Spring MVC) or a WebFluxRegistrations bean (Spring WebFlux).
