---------------------------------------
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).
