How to Fix CVE-2018-15795

To remediate this vulnerability, upgrade all affected Spring Framework 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.springframework.credhub:spring-credhub-core fixed: 1.1.0 
<dependency>
    <groupId>org.springframework.credhub</groupId>
    <artifactId>spring-credhub-core</artifactId>
    <version>1.1.0</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.springframework.credhub

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-15795, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.springframework.credhub

Analyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.springframework.credhub 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-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG), where the product uses a pseudo-random number generator (prng) in a security context, but the prng's algorithm is not cryptographically strong. In Spring Framework, 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

Pivotal CredHub Service Broker, versions prior to 1.1.0, uses a guessable form of random number generation in creating service broker's UAA client. A remote malicious user may guess the client secret and obtain or modify credentials for users of the CredHub Service.
