CERT Advisory CA-99-09 Array Services default configuration
Originally released: July 19, 1999
* IRIX systems running the Array Services daemon
* UNICOS systems running the Array Services daemon
A vulnerability has been discovered in the default configuration of
the Array Services daemon, arrayd. Array Services are used to manage a
cluster of systems. The default configuration file, arrayd.auth,
disables authentication and does not provide adequate protection for
systems connected to an untrusted network.
SGI has published the following document describing the vulnerability
On systems installed with the default configuration, remote and local
users can execute arbitrary commands as root.
Use "SIMPLE" authentication
Reconfigure arrayd to use "SIMPLE" authentication. For more
information about reconfiguring arrayd, please see the SGI security
Disable the arrayd daemon
If you do not need the capabilities provided by the arrayd daemon, you
may wish to disable the daemon.
The CERT Coordination Center would like to thank Yuri Volobuev and the
SGI Security Team for their assistance in preparing this advisory.
