Description

Impact

When opening a form in Valtimo, the access token (JWT) of the user is exposed to api.form.io via the the x-jwt-token header. An attacker can retrieve personal information from this token, or use it to execute requests to the Valtimo REST API on behalf of the logged-in user.

This issue is caused by a misconfiguration of the Form.io component.

Attack requirements

The following conditions have to be met in order to perform this attack:

  • An attacker needs to have access to the network traffic on the api.form.io domain.
  • The content of the x-jwt-token header is logged or otherwise available to the attacker.
  • An attacker needs to have network access to the Valtimo API.
  • An attacker needs to act within the time-to-live of the access token. The default TTL in Keycloak is 5 minutes.

Patches

Versions 10.8.4, 11.1.6 and 11.2.2 have been patched

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.
