How to Fix CVE-2020-1925

To remediate this vulnerability, upgrade all affected Odata client core 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.olingo:odata-client-core fixed: 4.7.1 
<dependency>
    <groupId>org.apache.olingo</groupId>
    <artifactId>odata-client-core</artifactId>
    <version>4.7.1</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.olingo

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-1925, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Odata client core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.7.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.olingo 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 Odata client core, 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

Apache Olingo versions 4.0.0 to 4.7.0 provide the AsyncRequestWrapperImpl class which reads a URL from the Location header, and then sends a GET or DELETE request to this URL. It may allow to implement a SSRF attack. If an attacker tricks a client to connect to a malicious server, the server can make the client call any URL including internal resources which are not directly accessible by the attacker.
