Executive Summary

This vulnerability involves IBM App Connect Enterprise and IBM Integration Bus for z/OS storing sensitive credential information in logs improperly. A local attacker could exploit this to access sensitive data that should remain confidential.

Detection Guidance

This vulnerability involves improper logging of credentials in IBM App Connect Enterprise and IBM Integration Bus for z/OS. Detection requires reviewing application logs for exposed credentials. Check log files in default directories like /var/log/ for entries containing 'password', 'credential', or 'login'. Use commands like grep -r 'password' /var/log/ to search for sensitive data leaks.

Impact Analysis

If you use affected versions of IBM App Connect Enterprise or IBM Integration Bus for z/OS, an attacker with local access could steal credentials logged by the system. This may lead to unauthorized access to systems or data protected by those credentials.

Compliance Impact

This vulnerability could violate compliance requirements that mandate protection of sensitive data, such as GDPR (data protection) or HIPAA (health information privacy). Improper logging of credentials risks unauthorized access, leading to potential non-compliance and legal consequences.

Mitigation Strategies

Review and update logging configurations to ensure credentials are not logged. Apply patches or updates provided by IBM for IBM App Connect Enterprise and IBM Integration Bus for z/OS. Restrict local access to systems where these products are installed.
