CVE-2024-4321 — Gaizhenbiao Chuanhuchatgpt security vulnerability

High CVSS 7.5

A Local File Inclusion (LFI) vulnerability exists in the gaizhenbiao/chuanhuchatgpt application, specifically within the functionality for uploading chat history. The vulnerability arises due to improper input validation when handling file paths during the chat history upload process. An attacker can exploit this vulnerability by intercepting requests and manipulating the 'name' parameter to specify arbitrary file paths. This allows the attacker to read sensitive files on the server, leading to information leakage, including API keys and private information. The issue affects version 20240310 of the application.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
