Title

BridgeHead FileStore < 24A Apache Axis2 Default Credentials RCE

Summary

BridgeHead FileStore versions prior to 24A (released in early 2024) expose the Apache Axis2 administration module on network-accessible endpoints with default credentials that allows unauthenticated remote attackers to execute arbitrary OS commands. Attackers can authenticate to the admin console using default credentials, upload a malicious Java archive as a web service, and execute arbitrary commands on the host via SOAP requests to the deployed service.
