CERT Advisory CA-99-10 Insecure Default Configuration on RaQ2 Servers

   Originally released: July 30, 1999
   Source: CERT/CC
   See also: Cobalt Networks Security Announcement

Systems Affected

     * Cobalt Networks RaQ2 single rack unit Internet servers

I. Description

   A vulnerability has been discovered in the default configuration of
   Cobalt Networks RaQ2 servers that allows remote users to install
   arbitrary software packages to the system. RaQ2 servers are configured
   with an administrative webserver to process remote requests to manage
   the unit. Systems installed with the default configuration have
   insufficient access control mechanisms to prevent remote users from
   adding arbitrary software packages to the system using this webserver.

   A document published by Cobalt Networks describes the vulnerability
   and solutions in more detail:

   http://www.cobaltnet.com/support/security/index.html

II. Impact

   Any remote user who can establish a connection to an administrative
   port on a vulnerable RaQ2 server can install arbitrary software
   packages on the server. This access can then be used to gain root
   privileges on the system.

III. Solution

   Configure your Systems to Guard Against this Vulnerability

   Install the patches provided by Cobalt Networks:

   http://www.cobaltnet.com/patches/RaQ2-Security-1.0.pkg (For RaQ2
          servers)

          versions of the RaQ2 system)
