How to Fix CVE-2018-11041

To remediate this vulnerability, upgrade all affected Cloudfoundry identity server 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.cloudfoundry.identity:cloudfoundry-identity-server fixed: 4.7.5 
<dependency>
    <groupId>org.cloudfoundry.identity</groupId>
    <artifactId>cloudfoundry-identity-server</artifactId>
    <version>4.7.5</version>
</dependency>
org.cloudfoundry.identity:cloudfoundry-identity-server fixed: 4.10.1 
<dependency>
    <groupId>org.cloudfoundry.identity</groupId>
    <artifactId>cloudfoundry-identity-server</artifactId>
    <version>4.10.1</version>
</dependency>
org.cloudfoundry.identity:cloudfoundry-identity-server fixed: 4.12.3 
<dependency>
    <groupId>org.cloudfoundry.identity</groupId>
    <artifactId>cloudfoundry-identity-server</artifactId>
    <version>4.12.3</version>
</dependency>
org.cloudfoundry.identity:cloudfoundry-identity-server fixed: 4.19.0 
<dependency>
    <groupId>org.cloudfoundry.identity</groupId>
    <artifactId>cloudfoundry-identity-server</artifactId>
    <version>4.19.0</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.cloudfoundry.identity

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-11041, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.cloudfoundry.identity

Analyze the terminal output to locate any version of Cloudfoundry identity server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.7.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.cloudfoundry.identity 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-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Cloudfoundry identity server, 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

Cloud Foundry UAA, versions later than 4.6.0 and prior to 4.19.0 except 4.10.1 and 4.7.5 and uaa-release versions later than v48 and prior to v60 except v55.1 and v52.9, does not validate redirect URL values on a form parameter used for internal UAA redirects on the login page, allowing open redirects. A remote attacker can craft a malicious link that, when clicked, will redirect users to arbitrary websites after a successful login attempt.
