How to Fix GHSA-q76j-58cx-wp5v

To remediate this vulnerability, upgrade all affected Rpki validator 3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

net.ripe.rpki:rpki-validator-3 fixed: 3.2-2020.10.28.23.06 
<dependency>
    <groupId>net.ripe.rpki</groupId>
    <artifactId>rpki-validator-3</artifactId>
    <version>3.2-2020.10.28.23.06</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=net.ripe.rpki

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-q76j-58cx-wp5v, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=net.ripe.rpki

Analyze the terminal output to locate any version of Rpki validator 3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2-2020.10.28.23.06), your application is affected.

Note: The mvn dependency:tree -Dincludes=net.ripe.rpki 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Rpki validator 3, 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

A vulnerability in RPKI manifest validation exists when objects on the manifest are hidden, or expired objects are replayed. An attacker successfully exploiting this vulnerability could prevent new ROAs from being received or selectively hide ROAs, causing routes to become INVALID. To exploit this vulnerability, an attacker would need to perform a man in the middle attack on the TLS connection between the validator and an RRDP repository or perform a man in the middle attack against a rsync-only repository. The update addresses the vulnerability by implementing validation methods from [RFC 6486bis](https://datatracker.ietf.org/doc/draft-ietf-sidrops-6486bis/00/) and enabling strict validation by default.
