Attack-Flow Graph

Impact Analysis

Exploitation of this vulnerability can allow an attacker to access or overwrite files on the server by traversing directories through the manipulated output_path argument.

This could lead to unauthorized disclosure of sensitive information, modification of important files, or disruption of service depending on what files are accessed or altered.

Since the exploit is remotely accessible and publicly available, the risk of attack is increased.

Executive Summary

This vulnerability exists in the Dayoooun hwpx-mcp 0.2.0 software, specifically in the MCP Interface component within the save_document, export_to_text, and export_to_html functions of the file mcp-server/src/index.ts.

The issue arises from improper handling of the argument output_path, which allows an attacker to perform a path traversal attack. This means an attacker can manipulate the file path to access directories and files outside the intended scope.

The vulnerability can be exploited remotely, and a public exploit is available.
