Description

Gradio apps vulnerable to timing attacks to guess password

Impact

This security policy is with regards to a timing attack that allows users of Gradio apps to potentially guess the password of password-protected Gradio apps. This relies on the fact that string comparisons in Python terminate early, as soon as there is a string mismatch. Because Gradio apps are, by default, not rate-limited, a user could brute-force millions of guesses to figure out the correct username and password.

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/e329f1fd38935213fe0e73962e8cbd5d3af6e87b

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: None.
  • Availability impact: None.
