How to Fix CVE-2019-10686

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: Latest secure release 
<dependency>
    <groupId>com.ctrip.framework.apollo</groupId>
    <artifactId>apollo</artifactId>
    <version>Latest secure release</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-2019-10686, 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 the patched release), 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. 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

An SSRF vulnerability was found in an API from Ctrip Apollo through 1.4.0-SNAPSHOT. An attacker may use it to do an intranet port scan or raise a GET request via `/system-info/health` because the `%23` substring is mishandled.
