Make the `/file` secure against file traversal attacks and SSRF

High
abidlabs published GHSA-6qm2-wpxq-7qh2 Dec 20, 2023

Package

pip gradio (pip)

Affected versions

< 4.11.0

Patched versions

4.11.0

Description

Older versions of gradio contained a vulnerability in the /file route which made them susceptible to file traversal attacks in which an attacker could access arbitrary files on a machine running a Gradio app with a public URL (e.g. if the demo was created with share=True, or on Hugging Face Spaces) if they knew the path of files to look for.

This was not possible through regular URLs passed into a browser, but it was possible through the use of programmatic tools such as curl with the --pass-as-is flag.

Furthermore, the /file route in Gradio apps also contained a vulnerability that made it possible to use it for SSRF attacks.

Both of these vulnerabilities have been fixed in gradio==4.11.0

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
