CVE-2024-1728: Gradio allows users to access arbitrary files

Should you act?

High exploit likelihood

EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
• EPSS 85.4%, percentile 99.7: FIRST’s model estimates a 85.4% chance of exploitation activity in the next 30 days, higher than 99.7% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes gradio (PyPI) < 4.19.2, fixed in 4.19.2. Check your lockfile, including transitive dependencies.

What it is

gradio-app/gradio is vulnerable to a local file inclusion vulnerability due to improper validation of user-supplied input in the UploadButton component. Attackers can exploit this vulnerability to read arbitrary files on the filesystem, such as private SSH keys, by manipulating the file path in the request to the /queue/join endpoint. This issue could potentially lead to remote code execution. The vulnerability is present in the handling of file upload paths, allowing attackers to redirect file uploads to unintended locations on the server.

From the GitHub advisory

Impact This vulnerability allows users of Gradio applications that have a public link (such as on Hugging Face Spaces) to access files on the machine hosting the Gradio application. This involves intercepting and modifying the network requests made by the Gradio app to the server.

Patches Yes, the problem has been patched in Gradio version 4.19.2 or higher. We have no knowledge of this exploit being used against users of Gradio applications, but we encourage all users to upgrade to Gradio 4.19.2 or higher.

Fixed in: https://github.com/gradio-app/gradio/commit/16fbe9cd0cffa9f2a824a0165beb43446114eec7 CVE: https://nvd.nist.gov/vuln/detail/CVE-2024-1728
