Introduction:
=============
myCare2x is an web application. All program modules and data accesses are processed in the server.
User only need a web browser, in order to use the myCare2x functions, so extensions or changes on
the modules need no interferences at the clients.

- Apache HTTPD Server
- MySQL Database
- PHP

The spirit of Open Source also takes effect on implemented server software. myCare2x is based upon
External linkApache as HTTP server and External linkMySQL as database management system. myCare2x is
written in External linkPHP - an easy to learn and powerful scripting language.

Abstract:
=========
The Vulnerability Laboratory Researcher Team discovered multiple web vulnerabilities in myCare v2x CMS.


Report-Timeline:
================
2012-05-03: Public or Non-Public Disclosure


Status:
========
Published


Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
1.1
Multiple remote SQL Injection vulnerabilities are detected in myCare2x Content Management System.
The vulnerability allows an attacker (remote) or local low privileged user account to inject/execute own sql commands
on the affected application dbms. Successful exploitation of the vulnerability results in dbms & application compromise.
The vulnerability is located on the username post method.

Vulnerable Module(s):
[+] &aktion + &callurl
[+] dept_nr
[+] pid
[+] Eintrag
[+] name_last

1.2
Multiple persistent input validation vulnerabilities are detected in myCare2x Content Management System.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent).
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent)
context manipulation. Exploitation requires low user inter action.


Vulnerable Module(s):
[+] New Person - Insert new Person - Firstname, Lastname & Nickname
[-] Index - Listing (index.php - Search Results - Name (middle) + Person Data Listing (right))

../4.png


1.3
Multiple non persistent cross site scripting vulnerabilities are detected in myCare2x Content Management System.
The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with high required
user inter action or local low privileged user account. Successful exploitation can result in account steal, phishing
& client-side content request manipulation.


Vulnerable Module(s):
[+] mycare_ward_print - Favorite
[+] mycare2x_pat_info - Aktion
[+] mycare2x_proc_search - LN
[+] zusatzcode

Proof of Concept:
=================
1.1
The SQL Injection vulnerabilities can be exploited by remote attacker without user inter action.

Risk:
=====
1.1
The security risk of the remote sql injection vulnerabilities are estimated as critical.

1.2
The security risk of the persistent input validation vulnerabilities are estimated as medium(+).

1.3
The security risk of the client side cross site scripting vulnerabilities are estimated as low(+).
