OpenEMR is Open Source electronic medical record and medical practice management software.
|
|
OpenEMR is best described as a "system" of programs. The main OpenEMR program consists of the electronic

OpenEMR can also be configured for insurance billing with FreeB, accounting with SQL-Ledger,
|
|
and access controls with php-GACL.

Vulnerability:
|
|
~~~~~~~~~~~~~~
|
|
|
|
I found vulnerability in interface/billing/billing_process.php
|
|
-----------------------interface/billing/billing_process.php-------------
|
|
....
|
|
<?
|
|
...
|
|
include_once("$srcdir/patient.inc");
|
|
include_once("$srcdir/billrep.inc");
|
|
...
|
|
----------------------------------------------------------
|
|
|
|
Input passed to the "$srcdir" parameter in billing_process.php is not
|
|
properly verified before being used. This can be exploited to execute
|
|
arbitrary PHP code by including files from local or external
|
|
resources.
|
|
|
|
|
|
Also affected files :
|
|
|
|
interface/billing/billing_report.php
|
|

|
|
<?

....
|
|
include_once($GLOBALS['srcdir'] . '/sql.inc');
