CVE-2022-22965

CVSS 9.8 CRITICALEPSS 99.7%● KEVCWE-94
In short

A vulnerability in Spring MVC/WebFlux applications allows attackers to execute arbitrary code on the server through data binding on Java 9+. This happens when the app runs on Tomcat as a WAR file, making it a critical threat to web applications.

Technical detail

CVE-2022-22965 exploits unsafe data binding in Spring Framework on JDK 9+ environments, allowing remote code execution via malicious input to Spring MVC/WebFlux endpoints. Attack requires application deployment as WAR on Tomcat; Spring Boot JAR deployments are not affected. Successful exploitation grants unauthenticated attackers full remote code execution capability.

Summary generated and translated by AI from the official description.
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.
