description

OpsTree REMS through 1.0.0 is affected by an authentication bypass in its login handling. An unauthenticated remote attacker may obtain a privileged JWT and administrative access if they can reach the login API.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Restrict network access to the REMS login API to trusted users and networks using a reverse proxy, firewall, or equivalent access control. Review for unauthorized administrative tokens and upgrade when a vendor-fixed release is available.
