Server-Side Request Forgery (SSRF)

CVE-2024-47167

High
9.8/10

Summary

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 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. This issue affects Gradio versions prior to 5.0.0b5.

CWE-918 - Server-Side Request Forgery (SSRF)

Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
