How to Fix CVE-2024-43397

To remediate this vulnerability, upgrade all affected Apollo dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.ctrip.framework.apollo:apollo fixed: 2.3.0 
<dependency>
    <groupId>com.ctrip.framework.apollo</groupId>
    <artifactId>apollo</artifactId>
    <version>2.3.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.ctrip.framework.apollo

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-43397, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.ctrip.framework.apollo

Analyze the terminal output to locate any version of Apollo in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.ctrip.framework.apollo 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Apollo, 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.

Source Advisory Statement

### Impact A vulnerability exists in the synchronization configuration feature that allows users to craft specific requests to bypass permission checks. This exploit enables them to modify a namespace without the necessary permissions. ### Patches The issue was addressed with an input parameter check in #5192, which was released in version [2.3.0](https://github.com/apolloconfig/apollo/releases/tag/v2.3.0). ### Workarounds To mitigate the issue without upgrading, follow the recommended practices to prevent Apollo from being exposed to the internet. ### Credits The vulnerability was reported and reproduced by [Lakeswang](https://github.com/Lakes-bitgetsec). ### References For any questions or comments regarding this advisory: * Open an issue in [issue](https://github.com/apolloconfig/apollo/issues) * Email us at [apollo-config@googlegroups.com](mailto:apollo-config@googlegroups.com)
