Executive Summary

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 are vulnerable to a buffer overflow issue. This means an attacker could potentially send specially crafted input to cause the system to exceed its memory buffer limits, leading to crashes or unexpected behavior.

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. Use the command 'show version' in the DataPower CLI or check the version in the web management interface.

Impact Analysis

This vulnerability could allow an attacker to disrupt services, cause denial of service, or execute arbitrary code on affected IBM DataPower Gateway systems. It may lead to unauthorized access, data leakage, or system instability if exploited.

Compliance Impact

The vulnerability is a buffer overflow 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. Buffer overflows can lead to unauthorized access, data corruption, or denial of service, which may impact compliance with GDPR (data integrity and confidentiality) and HIPAA (security of protected health information).

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 provided by IBM to address the buffer overflow vulnerability.
