Attack-Flow Graph

Executive Summary

IBM Concert versions 1.0.0 through 3.0.0 have a flaw where they run operating system commands without specifying full executable paths or properly controlling search path resolution. This allows attackers with local access to manipulate the search path and execute untrusted or malicious code.

Impact Analysis

An attacker with local system access could exploit this to run unauthorized commands, potentially gaining control over the system, stealing data, or installing malware. This could lead to data breaches, system compromise, or further network infiltration.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Update IBM Concert to the latest version where the issue is resolved. Review and restrict environment variables that affect executable path resolution. Ensure all system commands use fully qualified paths in the application code.
