How to Fix CVE-2018-1000111

To remediate this vulnerability, upgrade all affected Subversion 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.jenkins-ci.plugins:subversion fixed: 2.10.3 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>subversion</artifactId>
    <version>2.10.3</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.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-1000111, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

Analyze the terminal output to locate any version of Subversion in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins 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-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Subversion, 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 improper authorization vulnerability exists in Jenkins Subversion Plugin version 2.10.2 and earlier in `SubversionStatus.java` and `SubversionRepositoryStatus.java` that allows an attacker with network access to obtain a list of nodes and users. As of version 2.10.3, the class handling requests to /subversion/ no longer extends the class handling requests to the …/search/ sub-path, therefore any such requests will fail.
