CVE-2022-22965

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).

CVE-2022-22970

In spring framework versions prior to 5.3.20+ , 5.2.22+ and old unsupported versions, applications that handle file uploads are vulnerable to DoS attack if they rely on data binding to set a MultipartFile or javax.servlet.Part to a field in a model object.
