02 : Vulnerability details

Corelan Team has found 3 types of vulnerabilities in NolaPro :

Cross-Site Scripting (XSS)
SQL Injection
Information Disclosure

Cross-Site Scripting

We have found 3 instances of Cross-Site Scripting in Nolapro, one of which does not
require authentication. Please note that since Cross-Site Scripting is a client side
attack, the need for authentication does not reduce the risk and is indicated sollely
to facillitate reproducing the bugs.

XSS #1
Script: example.php Parameter: file Request: POST AuthRequired?: No

XSS #2
Script: sidemenu.php Parameter: menutitle Request: GET AuthRequired?: Yes

XSS #3
Script: nporderitemremote.php Parameter: linenum Request: GET AuthRequired?: Yes
We provide proof-of-concept for these bugs. These examples are inoffensive and will only
display an alert box in the browser.

XSS #1
Because this is a POST request, an easy way to reproduce the bug is to input the
following string on the example.php page :

XSS #2
http://nolapro_server/sidemenu.php?index=1&menutitle=%3Cscript%3Ealert%28String.fromCharCode%2888,83,83,32,102,111,117,110,100,32,98,121,32,67,111,114,101,108,97,110,32,84,101,97,109%29%29;%3C/script%3E&menutitleorig=STR_ORDERS

XSS #3
http://nolapro_server/nporderitemremote.php?pos_mode=1&currency=USD&curdate=2010-04-12&linenum=%3Cscript%3Ealert%28String.fromCharCode%2888,83,83,32,102,111,117,110,100,32,98,121,32,67,111,114,101,108,97,110,32,84,101,97,109%29%29;%3C/script%3E&inventorylocationid=1&customerid=&shiptoid=0

SQL Injection

We found one instance of SQL Injection in NolaPro. The vulnerable script is
invitemlstreorder.php and the parameter is vendorid.
To reproduce the bug, first input the value 1 on the invitemlstreorder.php page in the
box for the ID value. The server should respond almost instantly. Now input the following
value :

1 or BENCHMARK(2500000,MD5(1))

The server should take some time to respond (if the delay is too short, increase the
2500000 value).

Information Disclosure

The checkfile.php script gives indication on the existence of files on the server. This
information could be used by an attacker to gain information on the server and perform a
targeted attack. Access to this script should require authentication and be accessible to
administrators only.
