vantage6 vulnerable to a username timing attack on recover password/MFA token

Moderate severity GitHub Reviewed Published Mar 14, 2024 in vantage6/vantage6 • Updated Mar 15, 2024

Package

pip vantage6 (pip)

Affected versions

<= 4.2.2

Patched versions

4.3.0

Description

Impact

Much like GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes /recover/lost and /2fa/lost, which send emails to users if they have lost their password or MFA token. Usernames can be found by assessing response time differences, and additionally, they can be found because the endpoint gives a response "Failed to login" if the username exists.
