Attack-Flow Graph

Executive Summary

This vulnerability is a buffer overflow 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. A remote attacker could exploit this to cause a denial of service by sending specially crafted input that exceeds buffer limits.

Detection Guidance

Detection of this vulnerability requires checking the version of IBM DataPower Gateway installed on your system. Compare the installed version 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 'system version' in the DataPower CLI to verify the version.

Impact Analysis

If you use any of the affected IBM DataPower Gateway versions, an attacker could exploit this vulnerability to disrupt services, leading to downtime or unavailability of critical network functions. This could affect business operations relying on DataPower Gateway for processing.

Compliance Impact

The vulnerability allows remote attackers to cause a denial of service via buffer overflow, which could disrupt critical services handling sensitive data. This may impact compliance with GDPR by affecting availability of personal data processing systems and HIPAA by interrupting healthcare data operations.

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). Monitor IBM security advisories for updates and restrict network access to vulnerable systems until patched.
