GaiZhenbiao/ChuanhuChatGPT

A vulnerability in gaizhenbiao/chuanhuchatgpt version 20240628 allows for a Denial of Service (DOS) attack. When uploading a file, if an attacker appends a large number of characters to the end of a multipart boundary, the system will continuously process each character, rendering ChuanhuChatGPT inaccessible. This uncontrolled resource consumption can lead to prolonged unavailability of the service, disrupting operations and causing potential data inaccessibility and loss of productivity.

An arbitrary file read vulnerability exists in gaizhenbiao/chuanhuchatgpt version 20240628 due to insufficient validation when loading prompt template files. An attacker can read any file that matches specific criteria using an absolute path. The file must not have a .json extension and, except for the first line, every other line must contain commas. This vulnerability allows reading parts of format-compliant files, including code and log files, which may contain highly sensitive information such as account credentials.

In the latest version (20240628) of gaizhenbiao/chuanhuchatgpt, an issue exists in the /file endpoint that allows authenticated users to access the chat history of other users. When a user logs in, a directory is created in the history folder with the user's name. By manipulating the /file endpoint, an authenticated user can enumerate and access files in other users' directories, leading to unauthorized access to private chat histories. This vulnerability can be exploited to read any user's private chat history.

A file overwrite vulnerability exists in gaizhenbiao/chuanhuchatgpt versions <= 20240410. This vulnerability allows an attacker to gain unauthorized access to overwrite critical configuration files within the system. Exploiting this vulnerability can lead to unauthorized changes in system behavior or security settings. Additionally, tampering with these configuration files can result in a denial of service (DoS) condition, disrupting normal system operation.

A path traversal vulnerability exists in the latest version of gaizhenbiao/chuanhuchatgpt. The vulnerability arises from unsanitized input handling in multiple features, including user upload, directory creation, and template loading. Specifically, the load_chat_history function in modules/models/base_model.py allows arbitrary file uploads, potentially leading to remote code execution (RCE). The get_history_names function in utils.py permits arbitrary directory creation. Additionally, the load_template function in utils.py can be exploited to leak the first column of CSV files. These issues stem from improper sanitization of user inputs concatenated with directory paths using os.path.join.

The gaizhenbiao/chuanhuchatgpt application is vulnerable to a path traversal attack due to its use of an outdated gradio component. The application is designed to restrict user access to resources within the `web_assets` folder. However, the outdated version of gradio it employs is susceptible to path traversal, as identified in CVE-2023-51449. This vulnerability allows unauthorized users to bypass the intended restrictions and access sensitive files, such as `config.json`, which contains API keys. The issue affects the latest version of chuanhuchatgpt prior to the fixed version released on 20240305.

gaizhenbiao/chuanhuchatgpt is vulnerable to improper access control, allowing unauthorized access to the `config.json` file. This vulnerability is present in both authenticated and unauthenticated versions of the application, enabling attackers to obtain sensitive information such as API keys (`openai_api_key`, `google_palm_api_key`, `xmchat_api_key`, etc.), configuration details, and user credentials. The issue stems from the application's handling of HTTP requests for the `config.json` file, which does not properly restrict access based on user authentication.

ChuanhuChatGPT is a graphical user interface for ChatGPT and many large language models. A vulnerability in versions 20230526 and prior allows unauthorized access to the config.json file of the privately deployed ChuanghuChatGPT project, when authentication is not configured. The attacker can exploit this vulnerability to steal the API keys in the configuration file. The vulnerability has been fixed in commit bfac445. As a workaround, setting up access authentication can help mitigate the vulnerability.
