Attack-Flow Graph

Executive Summary

This 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. A remote authenticated attacker could exploit it to execute arbitrary code on the affected system.

Detection Guidance

Detection of this vulnerability requires checking the installed version of IBM DataPower Gateway against the affected versions (10.5.0.0-10.5.0.22, 10.6.1-10.6.6, 10.6.0.0-10.6.0.10, 11.0.0.0-11.0.0.2). Use commands like 'show version' or 'show system' in the DataPower CLI to verify the version.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your IBM DataPower Gateway, potentially leading to unauthorized access, data breaches, or system compromise. It requires remote authentication, so attackers must first gain access to the system.

Compliance Impact

This vulnerability could allow remote authenticated attackers to execute arbitrary code due to a buffer overflow, potentially leading to unauthorized access or data breaches. Such breaches may violate compliance requirements under GDPR (data protection) and HIPAA (healthcare data security) by exposing sensitive information.

Mitigation Strategies

Update IBM DataPower Gateway to a patched version. IBM recommends upgrading to versions beyond the affected ranges: 10.5.0.22, 10.6.6, 10.6.0.10, or 11.0.0.2.
