Subject: C4 Security Advisory - GE Fanuc Proficy Information Portal 2.6 Authentication Vulnerability|
GE-Fanuc's Proficy Information Portal 2.6 is a web based reporting
application for the SCADA environment. As such it will usually be installed
in a buffer zone between the SCADA and the corporate network, which makes it
a very sensitive application as it can access both networks.
The login process of Proficy involves sending the username in cleartext and
the password in Base64 encoded format. This transmition can potentially be
intercepted and decoded by an attacker with access to the data traffic.
An attacker can harvest user credentials by intercepting the traffic between
the browser and the Proficy server.
