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. It occurs due to improper bounds checking, allowing a local user to overflow the buffer and execute arbitrary code on the system.

Detection Guidance

This vulnerability is a local 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. Detection requires checking the installed version of IBM DataPower Gateway against these affected ranges.

Impact Analysis

An attacker with local access could exploit this to run malicious code, potentially gaining control over the system. This could lead to data breaches, unauthorized access, or system compromise.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR (data protection) and HIPAA (health data privacy) requirements. Organizations using affected versions may face compliance violations and penalties.

Mitigation Strategies

Apply the latest IBM DataPower Gateway patches or updates to versions beyond the affected ranges (10.5.0.22, 10.6.6, 10.6.0.10, 11.0.0.2). Disable local user access if not required and monitor for unusual system activity.
