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

CVE-2026-3366 is a security vulnerability in IBM InfoSphere Optim Test Data Fabrication that allows a remote attacker to perform a path traversal attack.

By sending a specially crafted URL containing "dot dot" sequences (/../), the attacker can traverse directories on the system and view arbitrary files that should be restricted.

This vulnerability is classified as CWE-22, which means improper limitation of a pathname to a restricted directory.

Impact Analysis

This vulnerability can have a significant impact because it allows an attacker to read arbitrary files on the affected system remotely without any authentication.

Such unauthorized access could expose sensitive or confidential information stored on the system, potentially leading to data breaches or information leakage.

The vulnerability has a high severity score of 7.5, indicating that it poses a serious security risk.

Detection Guidance

This vulnerability can be detected by monitoring for specially crafted URL requests containing "dot dot" sequences (/../) that attempt to traverse directories and access arbitrary files on the system.

Network or web server logs can be inspected for suspicious URL patterns including '/../' sequences.

Example commands to detect such attempts might include using grep on web server logs:

grep '/../' /var/log/httpd/access_log
grep '/../' /var/log/apache2/access.log
grep '/../' /path/to/infosphere/logs/*

Additionally, network intrusion detection systems (NIDS) can be configured to alert on URL patterns containing '/../'.

Mitigation Strategies

IBM has not provided a direct fix for this vulnerability but suggests contacting TechSupport for workaround instructions.

Immediate mitigation steps include:

Monitor and block suspicious URL requests containing '/../' sequences at the web server or network firewall level.
Restrict access to the affected IBM InfoSphere Optim Test Data Fabrication application to trusted networks or users.
Subscribe to IBM security notifications for updates and apply any future patches or fixes as soon as they become available.
