CERT Advisory CA-99-10 Insecure Default Configuration on RaQ2 Servers
Originally released: July 30, 1999

* Cobalt Networks RaQ2 single rack unit Internet servers
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:
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.
