CVE-2022-22947: Spring Framework Spring Cloud Gateway Vulnerable To Vulnerability
CRITICALCVE-2022-22947 is a CRITICAL (CVSS 10.0) spring cloud gateway vulnerable to vulnerability (CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')) affecting Spring Framework libraries in the Maven ecosystem. The issue involves spring cloud gateway vulnerable to code injection when gateway actuator endpoint enabled, exposed, unsecured. Remediation is available by upgrading affected packages to version 3.0.7, 3.1.1.

How to Fix CVE-2022-22947
To remediate this vulnerability, upgrade all affected Spring Framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gateway</artifactId>
<version>3.0.7</version>
</dependency><dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gateway</artifactId>
<version>3.1.1</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.springframework.cloudHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2022-22947, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.springframework.cloudAnalyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.7), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.springframework.cloud command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection'), where the product constructs all or part of an expression language (el) statement in a framework such as a java server page (jsp) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended el statement before it is executed. In Spring Framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
