  Novell GroupWise Servlet Gateway Default Username and Password
------------------------------------------------------------------------

SUMMARY

Novell GroupWise is installed with a default username and password that
controls the servlet manager. The servlet manager allows the configuration
of the servlets to be loaded, reloaded, or unloaded. This is more of an
annoyance than an exploit. The ability to control and unload servlets
allows an attacker to deny web-based services to users. This will prevent
users from accessing mail or other servlet based resources.

DETAILS

Vulnerable systems:
GroupWise 5.5 Enhancement Pack
GroupWise 6.0

Exploit:
http://server/servlet/ServletManager
username servlet
password manager

Solution:
Change the password:

Edit the SYS:\JAVA\SERVLETS\SERVLET.PROPERTIES file.
There is a section for ServletManager like the following:

# ServletManager servlet
servlet.ServletManager.code=com.novell.application.ServletGateway.ServletManager

servlet.ServletManager.initArgs=datamethod=POST,user=servlet,password=manager,bgcolor

#c0c0c0
servlet.ServletManager.preload=true
