CWE

KEV

CWE ID	Description
CWE-22	The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Attack-Flow Graph

Executive Summary

IBM i versions 7.6, 7.5, 7.4, and 7.3 have a path traversal vulnerability that allows a remote authenticated attacker to access sensitive information.

Detection Guidance

This vulnerability is specific to IBM i systems and involves path traversal. Detection requires checking for unauthorized access to sensitive files or directories. Review system logs for unusual file access patterns, especially from remote authenticated users. IBM i systems may require native commands like DSPLOG or QSYSOPR to inspect access logs. Ensure all IBM i versions (7.3 to 7.6) are updated with the latest fixes from IBM.

Impact Analysis

An attacker could exploit this to read sensitive files or data on the affected IBM i system, potentially leading to data breaches or unauthorized access.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR and HIPAA compliance requirements for data protection and confidentiality.

Mitigation Strategies

Apply the latest IBM i PTFs or updates provided by IBM to address the path traversal vulnerability. Ensure proper access controls are in place to limit remote authenticated user privileges.
