The VapidLabs Vulnerability Database

Sonata is a teleconfrencing solution developed by Voyant Technologies. This advisory concerns the Sonata application server and bridge componet of the Sonata package. The application server is an Ultra Sparc 5 running Solaris 2.x as required by Voyant technologies. The bridge is an IBM PC running OS/2 Warp. These hosts are usually built in house by Voyant personnel and installed at customer locations by a field engineer.

I. Application Server, Solaris 2.x

By using available default services on the host an attacker can enumerate accounts. Using this easily obtainable account information combined with poor password selection and weak file permissions a remote attacker can gain root access. The passwords guessed are the default for all installations of Sonata.

By default xhost authentication is disabled allowing a remote attacker to log key strokes and capture screen shots of the X console.

II. Bridging Server, OS/2 Warp.

These default passwords are also re-used on the bridging host (OS/2). Which has telnet enabled for remote administration.

I am not going to detail the exploit because the methods used to access these systems are only the most basic information gathering techniques one would use to audit a host.
