Exploitability

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 Concert versions 1.0.0 through 3.0.0 have a directory traversal vulnerability. This allows a remote attacker to access files outside intended directories by sending a URL with 'dot dot' sequences like '/../'.

Detection Guidance

To detect this vulnerability, inspect network traffic for URLs containing '/../' sequences or unusual file path traversal attempts. Check server logs for requests with 'dot dot' patterns. Use tools like curl to manually test endpoints for directory traversal by appending '/../' to URLs.

Impact Analysis

An attacker could view sensitive files on the system, potentially exposing confidential data such as configuration files, logs, or other restricted information.

Compliance Impact

This vulnerability could potentially expose sensitive files on the system, which may include personal data or protected health information. Unauthorized access to such data could lead to violations of GDPR or HIPAA if the exposed files contain regulated information.

Mitigation Strategies

Update IBM Concert to a version beyond 3.0.0 to address the directory traversal vulnerability. Ensure network access controls restrict unauthorized URL requests containing dot dot sequences (/../). Monitor system logs for suspicious file access patterns.
