3193143 - Security vulnerability CVE-2022-22965 vulnerability SprngBoot/ Spring4Shell for SAP Customer Data Cloud

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

Severity is critical unless otherwise noted.

• Spring Framework
  
  • 5.3.0 to 5.3.17
  • 5.2.0 to 5.2.19
  • Older, unsupported versions are also affected
