CVE-2022-22965: Spring Framework RCE via Data Binding on JDK 9+
Spring by VMware
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
Affected VMware Products and Versions
Severity is critical unless otherwise noted.
- 5.3.0 to 5.3.17
- 5.2.0 to 5.2.19
- Older, unsupported versions are also affected
Users of affected versions should apply the following mitigation: 5.3.x users should upgrade to 5.3.18+, 5.2.x users should upgrade to 5.2.20+. No other steps are necessary. There are other mitigation steps for applications that cannot upgrade to the above versions. Those are described in the early announcement blog post, listed under the Resources section. Releases that have fixed this issue include:
