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.

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

../2.png  
  
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))

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):

[+] mycare2x_pat_info - Aktion  
[+] mycare2x_proc_search - LN

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