OpenEMR affected by Multiple Vulnerabilities

The most popular open source electronic medical records (OpenEMR) is said to have multiple vulnerabilities by the Trustwave SpiderLabs.

It reported that with a guest access, mixed with some application issues the user was able to compromise with the server running OpenEMR and it even served as a dock for attacking the internal networks.

The Researcher found a SQL Injection vulnerability in "Reports > Visits > SuperBill > Dates" location. 

"By browsing to this page and dumping in junk in either the start or end date parameters", he saw the SQL error message saying "ERROR: query failed: select * from forms where form_name = 'New Patient Encounter' and date between 'a'' and '2013-07-12' order by date DESC"

It also claimed to dump most of the database contents and important datas of patients as well as numerous usernames and passwords." I let my GPU box chew on the password hashes for a bit, and kept poking at the application." (the blog says)

OpenEMR is also reported to have HTML injection/XSS on an 'Office Notes' page. The user was even able to beguile the user visiting the page to attempt authentication with his system, which was hosting a fake SMB server with static challenges:

"This allowed me to capture a handful of domain usernames and password hashes. In addition, I had some luck cracking the OpenEMR password hashes from earlier, and some of the passwords were re-used locally on the Linux system hosting OpenEMR, allowing me access via SSH."(SpiderLabs reports)

The OpenEMR has been informed of it and they have patched the vulnerabilities in the latest 4.1.1 patch.
