Attack-Flow Graph

Executive Summary

This is a heap-based buffer overflow vulnerability 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. A remote attacker could exploit this to cause a denial of service by sending specially crafted input that overflows a buffer in memory.

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 involves checking the installed version of IBM DataPower Gateway on your system. Use commands like 'show version' in the DataPower CLI or check the version in the web management interface.

Impact Analysis

If exploited, this vulnerability could cause your IBM DataPower Gateway to crash or become unresponsive, disrupting network traffic and services that rely on it. This may lead to downtime for applications or systems using the affected gateway.

Compliance Impact

This vulnerability could lead to a denial of service, which may disrupt the availability of critical systems. For GDPR, availability is a key principle, so prolonged outages could impact compliance. HIPAA requires safeguards for data availability, and disruptions may violate this requirement.

Mitigation Strategies

Update IBM DataPower Gateway to a patched version. For affected versions, apply fixes from IBM as soon as possible to address the heap-based buffer overflow issue.
