-----BEGIN PGP SIGNED MESSAGE----- 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.
