Title: Multiple Vulnerabilities found in Sonata teleconferencing  
Application.  
  
Class: Design Error

Vulnerability Description:  
  
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.  
  
Six vulnerabilities have been found in the application server host and  
Sonata package, they are categorized below:  
  
1) Reused default user accounts and passwords.  
  
2) Easily guessable passwords.  
  
3) Poor file permissions.  
  
4) Lack of host hardening.   
  
5) X console authentication has been disabled.  
  
6) Hard coded default passwords.  
  
  
Vulnerable Packages/Systems: Sonata v3.x on Solaris 2.x.   
Sonata bridge OS/2 Warp.  
  
  
Solution/Vendor Information/Workaround:   
  
The vendor is currently working on a solution. See references section  
for Vendor contact information.

Technical Description - Exploit/Concept Code:  
  
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.
