EmbryoCore CMS v1.03 - Multiple Web Vulnerabilities




EmbryoCore is a blog / content management system written using PHP5 s newest features. Highly 
customizable, XHTML:Strict compliant, with full integration of jQuery for dynamic ajax-powered content.

The Vulnerability Laboratory Researcher Team discovered multiple Web Vulnerabilities in EmbryoCore v1.03.

2012-04-14:	Public or Non-Public Disclosure




A remote SQL Injection vulnerability (POST) is detected in EmbryoCore v1.03 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):
				[+] Add User or Register User Request (POST) [embryocore/index.php?event=admin:auser]

--- SQL Exception Logs ---
<div style=``display: none; opacity: 1;`` id=``kmessage`` class=``no-display``><img src=``
content/themes/admin/images/apply.png`` alt=``> <strong>EmbryoCore Fatal Database error:</strong> [42000]: 
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server 
version for the right syntax to use near ``=> ``></div>


A persistent input validation vulnerability is detected in the EmbryoCore v1.03 web application.
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 because the admin needs to watch the user list.
The user includes his scriptcode as profile name and the code is getting executed on the administrator section 

Vulnerable Module(s):
				[+] Profil & Username Input Field
				  [-] Admin Control Panel - User Listing 


Proof of Concept:
The sql injection vulnerability can be exploited by remote attackers without inter action or local low 
privileged user accounts. For demonstration or reproduce ...

To inject the sql command implement your statement on the user input fields and send it with the request (POST Method).
The return will be the error or successful query of the application dbms.

POST:	/embryocore/index.php?ajax=admin:auser&mode=createNewUser HTTP/1.1
POC: 	user_displayname=[SQL-INJECTION]&user_login=test2&user_email=m@....empire&user_password=123456&user_cpassword=hack4best

The persistent input validation vulnerability can be exploited by remote attackers without inter action 
or local low privileged 
user accounts. Successful exploitation requires low user inter action because the admin only have to review the user listing. 
For demonstration or reproduce ...

User Listing PoC:
<tr><td style="width: 1%; vertical-align: top;"><img src="
modules%2Ftemplate%2Fimages%2Fdefault_gravatar.png" alt="gravatar" style="width: 45px;">&#8203;&#8203;&#8203;&#8203;&#8203;</td><td style="
width: 15%; vertical-align: top;"><div class="list-title"><strong>-2</strong></div>"><iframe src="" width"500"="" height="500"><br /></td><td style='
width: 20%; vertical-align: top;'>Joined:<br />Monday 09th April 2012, 04:33am</td><td 
style='width: 20%; vertical-align: top;'>Last Visit:<br />-</td><td style='width: 20%; 
vertical-align: top;'>Last Post:<br />-</td><td style='width: 2%; vertical-align: top; 
text-align: right;'><img src='' 
alt='comments' title='comments' /> 0</td></tr>

The security risk of the sql injection vulnerability via post method is estimated as high(-).

The security risk of the persistent vulnerability is estimated as medium(+).
