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.sap.cloud.security

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-50422, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.sap.cloud.security

Analyze the terminal output to locate any version of Java security in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.17.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.sap.cloud.security 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-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Java security, 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 SAP BTP Security Services Integration Library ([Java] cloud-security-services-integration-library) allows under certain conditions an escalation of privileges. On successful exploitation, an unauthenticated attacker can obtain arbitrary permissions within the application. ### Patches Upgrade to patched version >= 2.17.0 or >= 3.3.0 We always recommend to upgrade to the latest released version. ### Workarounds No workarounds ### References https://www.cve.org/CVERecord?id=CVE-2023-50422
