Internet Security Systems (ISS) X-Force has identified a backdoor password in the Red Hat Linux Piranha product. Piranha is a package distributed by Red Hat, Inc. that contains the Linux Virtual Server (LVS) software, a web-based GUI, and monitoring and fail-over components. A backdoor password exists in the GUI portion of Piranha that may allow remote attackers to execute commands on the server. If an affected version of Piranha is installed and the default backdoor password remains unchanged, any remote as well as local user may login to the LVS web interface. From here LVS parameters can be changed and arbitrary commands can be executed with the same privilege as that of the web server.
