Attack-Flow Graph

Executive Summary

This vulnerability is a denial of service issue in IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2. It occurs due to an out-of-bounds memory access caused by a strict-weak-ordering violation in a sorting comparator, allowing a remote attacker to disrupt service.

Detection Guidance

This vulnerability is specific to IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2. Detection requires checking the installed version of IBM DataPower Gateway on your system.

Impact Analysis

If exploited, this vulnerability could allow an attacker to cause a denial of service, leading to service disruptions, downtime, or reduced availability of the IBM DataPower Gateway. This may affect business operations relying on the gateway for critical functions.

Compliance Impact

This vulnerability causes a denial of service due to out-of-bounds memory access, which could disrupt services handling sensitive data. For GDPR, this may impact availability of personal data processing systems, potentially violating Article 32 requirements for security and resilience. For HIPAA, service disruptions could affect access to protected health information, potentially compromising the integrity and availability requirements of the Security Rule.

Mitigation Strategies

Upgrade IBM DataPower Gateway to a version beyond the affected range (10.5.0.0-10.5.0.22, 10.6.0.0-10.6.6, 10.6.0.0-10.6.0.10, 11.0.0.0-11.0.0.2). Apply patches or updates from IBM as soon as they are available.
