CVE-2023-25823: Update share links to use FRP instead of SSH tunneling
Gradio is an open-source Python library to build machine learning and data science demos and web applications. Versions prior to 3.13.1 contain Use of Hard-coded Credentials. When using Gradio’s share links (i.e. creating a Gradio app and then setting share=True), a private SSH key is sent to any user that connects to the Gradio machine, which means that a user could access other users’ shared Gradio demos. From there, other exploits are possible depending on the level of access/exposure the Gradio app provides. This issue is patched in version 3.13.1, however, users are recommended to update to 3.19.1 or later where the FRP solution has been properly tested.
Impact
This is a vulnerability which affects anyone using Gradio’s share links (i.e. creating a Gradio app and then setting share=True) with Gradio versions older than 3.13.1. In these older versions of Gradio, a private SSH key is sent to any user that connects to the Gradio machine, which means that a user could access other users’ shared Gradio demos. From there, other exploits are possible depending on the level of access/exposure the Gradio app provides.
Patches
The problem has been patched. Ideally, users should upgrade to gradio==3.19.1 or later where the FRP solution has been properly tested.
