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 '/../'.

Impact Analysis

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