              `-----------* ID: PISA-24-APR-00-005 *-----------'
                    Issued by: David Webster <cog@seul.org>

Issue Date: 24-APR-00

Overview: Backdoor in Linux Virtual Server (LVS) package 

Affected: Indy 6.2build before current date 
		(earlier versions NOT affected)

                                  -=-=-==-=-=-

Detailed Problem Description:

	Internet Security Systems (ISS) X-Force has found a backdoor 
	password in the Piranha-gui product. 

	Piranha is a collection of utilities used to administer the Linux 
	Virtual Server. LVS is a scalable and highly available server 
	designed for large enterprise environments. It allows seamless 
	clustering of multiple web servers through load balancing, heartbeat
	monitoring, redundancy, and fail-over protection. To the end user,
	the entire system is completely transparent, appearing as if a 
	single server is fielding every request.

	Piranha ships with a web-based GUI (Piranha-gui) that allows 
	administrators to configure and monitor the web servers. The 
	Piranha package contains a backdoor account and password that 
	may allow a remote attacker access to the LVS web administration 
	tools. Attackers could then use these tools to cause the 
	interface to execute their commands against the server. With this 
	backdoor password, an attacker could potentially compromise the 
	web server and deface/destroy the entire web site.

	The vulnerability is present even if the LVS service isn't in use 
	on the system. If the "piranha-gui" package is installed and the 
	password has not been changed by the administrator, the system is
	vulnerable.  

Solution:

        Update the affected RPM packages by downloading and
        installing the RPMs listed below. For each RPM, run:

                root# rpm -Fvh <filename>

        where <filename> is the name of the RPM.

        [Note: You need only install EITHER the compiled RPM,
        (*.i386.rpm) OR the source RPM, (*.src.rpm), NOT both.]
