Re: Vulnerability discovered on Lotus Domino server "admin4.nsf"

["Alex Kloss" <alexkloss () att net>]

	From what I've gathered, it would appear that Lotus is aware that  
"admin4.nsf" is accessible by unauthenticated users. A Google search  
revealed that the L0pht team discovered a vulnerability in Domino that  
lets unauthenticated users view admin4.nsf.
	In addition to this, it also looks like you can change the file's data  
and potentially alter the site's intended behavior. If the site hasn't  
prohibited directory browsing, you should also be able to view the  
directory with the command "http://www.example.com/?open"; and view the  
admin4.nsf file with "http://example.com/admin4.nsf"; and get some useful  
information from there.

Hope this helps.
