Known Vulnerabilities
CVE-2024-48052
In gradio <=4.42.0, the gr.DownloadButton function has a hidden server-side request forgery (SSRF) vulnerability. The reason is that within the save_url_to_cache function, there are no restrictions on the URL, which allows access to local target resources. This can lead to the download of local resources and sensitive information.
CVE-2024-47870
Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves a **race condition** in the `update_root_in_config` function, allowing an attacker to modify the `root` URL used by the Gradio frontend to communicate with the backend. By exploiting this flaw, an attacker can redirect user traffic to a malicious server. This could lead to the interception of sensitive data such as authentication credentials or uploaded files. This impacts all users who connect to a Gradio server, especially those exposed to the internet, where malicious actors could exploit this race condition. Users are advised to upgrade to `gradio>=5` to address this issue. There are no known workarounds for this issue.
CVE-2024-47872
Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves **Cross-Site Scripting (XSS)** on any Gradio server that allows file uploads. Authenticated users can upload files such as HTML, JavaScript, or SVG files containing malicious scripts. When other users download or view these files, the scripts will execute in their browser, allowing attackers to perform unauthorized actions or steal sensitive information from their sessions. This impacts any Gradio server that allows file uploads, particularly those using components that process or display user-uploaded files. Users are advised to upgrade to `gradio>=5` to address this issue. As a workaround, users can restrict the types of files that can be uploaded to the Gradio server by limiting uploads to non-executable file types such as images or text. Additionally, developers can implement server-side validation to sanitize uploaded files, ensuring that HTML, JavaScript, and SVG files are properly handled or rejected before being stored or displayed to users.
CVE-2024-47084
Gradio is an open-source Python package designed for quick prototyping. This vulnerability is related to **CORS origin validation**, where the Gradio server fails to validate the request origin when a cookie is present. This allows an attacker’s website to make unauthorized requests to a local Gradio server. Potentially, attackers can upload files, steal authentication tokens, and access user data if the victim visits a malicious website while logged into Gradio. This impacts users who have deployed Gradio locally and use basic authentication. Users are advised to upgrade to `gradio>4.44` to address this issue. As a workaround, users can manually enforce stricter CORS origin validation by modifying the `CustomCORSMiddleware` class in their local Gradio server code. Specifically, they can bypass the condition that skips CORS validation for requests containing cookies to prevent potential exploitation.
CVE-2024-47165
Gradio is an open-source Python package designed for quick prototyping. This vulnerability relates to **CORS origin validation accepting a null origin**. When a Gradio server is deployed locally, the `localhost_aliases` variable includes "null" as a valid origin. This allows attackers to make unauthorized requests from sandboxed iframes or other sources with a null origin, potentially leading to data theft, such as user authentication tokens or uploaded files. This impacts users running Gradio locally, especially those using basic authentication. Users are advised to upgrade to `gradio>=5.0` to address this issue. As a workaround, users can manually modify the `localhost_aliases` list in their local Gradio deployment to exclude "null" as a valid origin. By removing this value, the Gradio server will no longer accept requests from sandboxed iframes or sources with a null origin, mitigating the potential for exploitation.
CVE-2024-47167
Gradio is an open-source Python package designed for quick prototyping. This vulnerability relates to **Server-Side Request Forgery (SSRF)** in the `/queue/join` endpoint. Gradio’s `async_save_url_to_cache` function allows attackers to force the Gradio server to send HTTP requests to user-controlled URLs. This could enable attackers to target internal servers or services within a local network and possibly exfiltrate data or cause unwanted internal requests. Additionally, the content from these URLs is stored locally, making it easier for attackers to upload potentially malicious files to the server. This impacts users deploying Gradio servers that use components like the Video component which involve URL fetching. Users are advised to upgrade to `gradio>=5` to address this issue. As a workaround, users can disable or heavily restrict URL-based inputs in their Gradio applications to trusted domains only. Additionally, implementing stricter URL validation (such as allowinglist-based validation) and ensuring that local or internal network addresses cannot be requested via the `/queue/join` endpoint can help mitigate the risk of SSRF attacks.
CVE-2024-4325
A Server-Side Request Forgery (SSRF) vulnerability exists in the gradio-app/gradio version 4.21.0, specifically within the `/queue/join` endpoint and the `save_url_to_cache` function. The vulnerability arises when the `path` value, obtained from the user and expected to be a URL, is used to make an HTTP request without sufficient validation checks. This flaw allows an attacker to send crafted requests that could lead to unauthorized access to the local network or the AWS metadata endpoint, thereby compromising the security of internal servers.
CVE-2024-4253
A command injection vulnerability exists in the gradio-app/gradio repository, specifically within the 'test-functional.yml' workflow. The vulnerability arises due to improper neutralization of special elements used in a command, allowing for unauthorized modification of the base repository or secrets exfiltration. The issue affects versions up to and including '@gradio/[email protected]'. The flaw is present in the workflow's handling of GitHub context information, where it echoes the full name of the head repository, the head branch, and the workflow reference without adequate sanitization. This could potentially lead to the exfiltration of sensitive secrets such as 'GITHUB_TOKEN', 'COMMENT_TOKEN', and 'CHROMATIC_PROJECT_TOKEN'.
CVE-2024-1183
An SSRF (Server-Side Request Forgery) vulnerability exists in the gradio-app/gradio repository, allowing attackers to scan and identify open ports within an internal network. By manipulating the 'file' parameter in a GET request, an attacker can discern the status of internal ports based on the presence of a 'Location' header or a 'File not allowed' error in the response.
CVE-2024-1729
A timing attack vulnerability exists in the gradio-app/gradio repository, specifically within the login function in routes.py. The vulnerability arises from the use of a direct comparison operation (`app.auth[username] == password`) to validate user credentials, which can be exploited to guess passwords based on response times. Successful exploitation of this vulnerability could allow an attacker to bypass authentication mechanisms and gain unauthorized access.
CVE-2024-2206
An SSRF vulnerability exists in the gradio-app/gradio due to insufficient validation of user-supplied URLs in the `/proxy` route. Attackers can exploit this vulnerability by manipulating the `self.replica_urls` set through the `X-Direct-Url` header in requests to the `/` and `/config` routes, allowing the addition of arbitrary URLs for proxying. This flaw enables unauthorized proxying of requests and potential access to internal endpoints within the Hugging Face space. The issue arises from the application's inadequate checking of safe URLs in the `build_proxy_request` function.
