Georgi Guninski security advisory #32, 2001

Lotus Domino 5.0.5 Web Server vulnerability - reading files outside the web root

Systems affected:

any derivatives thereof.


Lotus Domino Web Server under Windows 2000 (have not tested other versions) allows reading

files outside the web root.


The problem are URLs like:




which read c:\winnt\win.ini.

Note that above URL does not work in IE - for some strange reasons IE strips .nsf/../

so try it from Netscape or direct HTTP request.

Vendor status:

Sent several emails to Lotus/IBM on 3 January but did not hear back from them.
