Executive Summary

This vulnerability is a denial of service issue in IBM WebSphere Application Server versions 9.0, 8.5, and Liberty 17.0.0.3 through 26.0.0.7. It occurs because the HTTP channel does not limit resource allocation, allowing attackers to consume excessive system resources and crash the server.

Impact Analysis

An attacker could exploit this flaw to make the affected WebSphere server unresponsive or crash, disrupting services for users and applications relying on it. This could lead to downtime, data unavailability, and potential financial or operational losses.

Compliance Impact

This vulnerability could impact compliance by causing service disruptions that violate availability requirements in GDPR or HIPAA. Downtime may lead to unauthorized access risks or failure to meet data protection standards, potentially resulting in penalties or legal consequences.

Mitigation Strategies

Apply the latest IBM WebSphere Application Server or Liberty updates to versions beyond 26.0.0.7. Monitor IBM security advisories for patches and restrict HTTP channel resource allocations to prevent unbounded resource usage.
