How to Fix CVE-2023-25753

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

org.apache.shenyu:shenyu-admin fixed: 2.6.0 
<dependency>
    <groupId>org.apache.shenyu</groupId>
    <artifactId>shenyu-admin</artifactId>
    <version>2.6.0</version>
</dependency>
org.apache.shenyu:shenyu-common fixed: 2.6.0 
<dependency>
    <groupId>org.apache.shenyu</groupId>
    <artifactId>shenyu-common</artifactId>
    <version>2.6.0</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=org.apache.shenyu

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-25753, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.shenyu

Analyze the terminal output to locate any version of Shenyu admin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.shenyu 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 Shenyu admin, 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

There exists an SSRF (Server-Side Request Forgery) vulnerability located at the `/sandbox/proxyGateway` endpoint. This vulnerability allows us to manipulate arbitrary requests and retrieve corresponding responses by inputting any URL into the requestUrl parameter. Of particular concern is our ability to exert control over the HTTP method, cookies, IP address, and headers. This effectively grants us the capability to dispatch complete HTTP requests to hosts of our choosing. This issue affects Apache ShenYu: 2.5.1. Upgrade to Apache ShenYu 2.6.0 or apply patch  https://github.com/apache/shenyu/pull/4776  .
