Summary
In versions prior to 5.0.0 of the vantage6 software, the default user `root` with the password `root` poses a significant security risk. Attackers can easily gain access to the system as many vantage6 servers have this user with admin rights.
Risk Assessment
Organizations may be exposed to unauthorized access and potential data breaches if default login credentials are not changed. This can lead to serious consequences, including data loss and reputational damage.
Recommendation
It is recommended to upgrade to version 5.0.0 or to delete the `root` user after creating other users. Additionally, ensure that all default passwords are changed to stronger ones.
Other vulnerabilities in vantage6
See all- CVE-2026-73652High
vantage6 version 5.0.2 and earlier has an algorithm-store edit permission lacking an ownership check, allowing one algorithm developer to alter another developer's algorithm while it is pending or under review. The attacker can change metadata including the algorithm image or image tag, causing reviewers and nodes to trust a different image from the one originally submitted. No fixed version is available as of this review.
- CVE-2026-54533Medium
In versions prior to 5.0.0 of vantage6, malicious algorithms can potentially access other algorithms' input and output files. The issue is fixed in version 5.0.0.
- CVE-2024-27928Medium
In versions prior to 5.0.0 of the vantage6 software, an attacker who gains access to a user's email account can reset the password and the 2FA token via email, reducing security to a single authentication factor (email access). Version 5.0.0 fixes this issue.
- CVE-2024-24769Low
In versions prior to 5.0.0, users can reset their MFA tokens via API routes that send them emails. The number of emails sent is not limited, allowing attackers to flood users' mailboxes.
Original NVD description (English source)
vantage6 is an open-source infrastructure for privacy preserving analysis. Versions prior to 5.0.0 provide an initial user with username `root` and password `root`. This is not ideal because attackers know that almost all vantage6 servers have a user with username `root` that probably has admin rights, and the initial password is very weak and it is possible that administrators forget to reset it. Version 5.0.0 fixes the issue. As a workaround, it is possible to delete the `root` user after it has been used to create other users.
