CVE-2024-5278: 
vulnerability analysis and mitigation

CVE-2024-5278 affects gaizhenbiao/chuanhuchatgpt and involves an unrestricted file upload vulnerability in the /upload endpoint. The vulnerability was discovered in the latest version as of March 10, 2024, and allows attackers to upload files with arbitrary extensions due to insufficient validation in the handle_file_upload function (NVD).

The vulnerability stems from insufficient validation of uploaded file types in the /upload endpoint. Specifically, the handle_file_upload function does not perform proper sanitization or validation of file extensions or content types, allowing attackers to upload potentially malicious files including HTML files with XSS payloads and Python files. The vulnerability has been assigned a CVSS v3.1 base score of 6.1 (MEDIUM) with vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N (NVD).

The vulnerability can lead to stored Cross-Site Scripting (XSS) attacks and potentially result in remote code execution (RCE) on the server hosting the application. This could allow attackers to execute arbitrary code and compromise the system's security (NVD).

The vulnerability affects versions up to March 10, 2024. Users should update to version 20240919 or later which includes fixes for this vulnerability. In the absence of an update, it is recommended to implement proper file type validation and sanitization at the upload endpoint (NVD).
