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.
