Verax NMS Password Replay Attack

Posted Mar 7, 2013

Authored by Andrew Brooks

The primary client-side UI component of Verax NMS is a flash component named clientMain.swf. In addition to the Flash UI, Verax NMS uses AMF remoting for client/server communications. As part of the login process, when a user logs in to the application, two parameters (username and password) are passed to the authenticateUser operation, which is part of the userService destination. Before this information is sent to the server, the password is encrypted client-side using an implementation of RSA. Due to the fact that the private and public keys are hardcoded into clientMain.swf the encrypted password could be captured and replayed against the service by an attacker. All versions of Verax NMS prior to 2.1.0 are vulnerable.
