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

This vulnerability is a path traversal issue in bleenco abstruse up to version 2.1.0. It exists in the Cache Endpoint's file server/api/worker/download_cache.go component, specifically in the filepath.Join function. An attacker can manipulate the File argument to perform path traversal attacks, potentially accessing unauthorized files on the server.

Detection Guidance

Detecting this vulnerability requires checking for path traversal attempts in the Cache Endpoint of bleenco abstruse versions up to 2.1.0. Monitor server logs for unusual file access patterns or requests containing sequences like '../' or '..%2f'. Inspect network traffic for suspicious download_cache.go interactions.

Impact Analysis

This vulnerability allows remote attackers to access sensitive files on the server by manipulating file paths. If exploited, it could lead to unauthorized data disclosure, file corruption, or system compromise depending on the server's configuration and permissions.

Compliance Impact

This vulnerability could lead to non-compliance with data protection regulations like GDPR or HIPAA if it results in unauthorized access to personal or health data. Organizations may face legal penalties, reputational damage, and loss of customer trust due to data breaches caused by this issue.

Mitigation Strategies

Immediately update bleenco abstruse to a version beyond 2.1.0 if available. If no patch exists, disable the Cache Endpoint or restrict access to the file server/api/worker/download_cache.go component. Implement input validation to sanitize file paths and block traversal sequences.
