Name of the Vulnerable Software and Affected Versions
Mysterium Node versions prior to 1.36.0
Description
Improper authorization in the '/tequilapi/config/user' endpoint allows unauthenticated attackers to arbitrarily overwrite the node configuration. This can be achieved by sending a crafted POST request, potentially leading to a full node takeover.
Recommendations
Update Mysterium Node to version 1.36.0 or later.
As a temporary workaround, restrict access to the '/tequilapi/config/user' endpoint to minimize the risk of exploitation.
