CVE-2022-22965
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCVE-2022-22965 (Spring4Shell) is a critical RCE vulnerability in Spring Framework affecting applications running on JDK 9+ when deployed as WAR on Tomcat. The exploit abuses Spring's data binding mechanism to achieve remote code execution. Spring Boot applications deployed as executable JARs (the default) are NOT vulnerable to the specific exploit, but may still be at risk if running vulnerable Spring Framework versions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Spring Framework version in useCheck your application's dependency tree (Maven pom.xml, Gradle build.gradle, or lib directory) for spring-core, spring-beans, or spring-webmvc JAR files and note their version numbersAffected if The Spring Framework version is < 5.2.20 OR >= 5.3.0 AND < 5.3.18
-
Verify JDK versionRun java -version from the command line or check the Java runtime configured for your Tomcat processAffected if JDK 9 or higher is in use (versions 9, 10, 11, 17, etc.)
-
Confirm WAR deployment on TomcatInspect your deployment artifact - if it is a .war file deployed to a Tomcat servlet container rather than an executable JAR, the application is in the vulnerable configurationAffected if The application is deployed as a WAR file to Apache Tomcat
-
Check if Spring data binding is in useReview application code for use of @ModelAttribute parameters in controllers, or check for DataBinder configuration - this feature is required for exploitationAffected if Spring MVC data binding through @ModelAttribute or explicit DataBinder is enabled in the application
Your environment is affected if you run a Spring Framework version < 5.2.20 or >= 5.3.0 but < 5.3.18, deployed as a WAR on Tomcat, using JDK 9+, with Spring data binding enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.1.05.2.205.3.18
Upgrade Spring Framework to 5.3.18+, 5.2.20+, or later patched versions. Alternatively, migrate to Spring Boot 2.6.6+ or 2.5.12+ which bundle patched Spring Framework. If upgrade is not immediately feasible, consider temporarily deploying as executable JAR or downgrading to JDK 8 as a workaround.
Spring Framework 5.2.20+ or 5.3.18+ (or Spring Boot that includes these fixed versions)
- Identify all applications using affected Spring Framework versions (< 5.2.20 or >= 5.3.0 but < 5.3.18)
- For Spring Framework 5.2.x line: upgrade to version 5.2.20 or later
- For Spring Framework 5.3.x line: upgrade to version 5.3.18 or later
- If using Spring Boot, ensure it bundles a fixed Spring Framework version
- Test the upgrade in a non-production environment to verify functionality
- Deploy the fixed version to production
