What is CVE-2024-34706?
CVE-2024-34706 is a critical vulnerability in valtimo-platform valtimo-frontend-libraries, published on 13 May 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Valtimo is an open source business process and case management platform. 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.
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; and an attacker needs to act within the time-to-live of the access token. The default TTL in Keycloak is 5 minutes.
Versions 10.8.4, 11.1.6 and 11.2.2 have been patched.
Weakness: CWE-532
