Description

This security bulletin contains information about 1 vulnerability.


1) Missing Authentication for Critical Function (CVE-ID: N/A)

CWE-ID: CWE-306 - Missing Authentication for Critical Function

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to modify database contents and cause a denial of service.

The vulnerability exists due to missing authentication in the `importBoard` Meteor DDP method in `models/import.js` when handling crafted DDP requests over WebSocket. A remote attacker can send a specially crafted request to modify database contents and cause a denial of service.

On default installations, the import feature is enabled, and the method can be reached through the `/sockjs/` endpoint without credentials. The issue affects shared and multi-tenant deployments on the same instance.
