vaadin: Exposure of Sensitive Information to an Unauthorized Actor

Published Updated By the CyberSecBulletin desk

CVE-2022-29567 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in vaadin, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 23.1.0.beta1 as the first without the flaw, so updating vaadin to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1% chance of exploitation within 30 days, higher than 63% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update vaadin to 23.1.0.beta1 or a later version.
  2. Update vaadin-grid-flow to 23.1.0.beta1 or a later version.
  3. Read the advisory on vaadin.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The default configuration of a TreeGrid component uses Object::toString as a key on the client-side and server communication in Vaadin 14.8.5 through 14.8.9, 22.0.6 through 22.0.14, 23.0.0.beta2 through 23.0.8 and 23.1.0.alpha1 through 23.1.0.alpha4, resulting in potential information disclosure of values that should not be available on the client-side.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
