Attack-Flow Graph

Executive Summary

IBM WebSphere Application Server Liberty versions 17.0.0.3 through 26.0.0.8 ND Collective Controller has a path-segment injection vulnerability in its collective routing mechanism. This allows an attacker to manipulate path segments, potentially leading to unauthorized access or data exposure.

Detection Guidance

This vulnerability can be detected by checking the version of IBM WebSphere Application Server Liberty running on your system. If the version is between 17.0.0.3 and 26.0.0.8, it is potentially vulnerable. Use commands like 'java -jar /path/to/wlp/bin/productInfo.sh version' or check the installed package version via system package managers.

Impact Analysis

This vulnerability could allow an attacker to inject malicious path segments, potentially bypassing security controls, accessing restricted resources, or exfiltrating sensitive data from the affected WebSphere Liberty server.

Compliance Impact

The vulnerability may expose sensitive data due to unauthorized path manipulation in the collective routing mechanism, potentially violating confidentiality requirements in GDPR and HIPAA. However, specific compliance impacts depend on deployment context and data handling practices.

Mitigation Strategies

Upgrade IBM WebSphere Application Server Liberty to a version beyond 26.0.0.8 to address the path-segment injection vulnerability in the collective routing mechanism.
