Document Title: =============== Elite Graphix ElitCMS 1.01 & PRO - Multiple Web Vulnerabilities References (Source): ==================== http://www.vulnerability-lab.com/get_content.php?id=1117 Release Date: ============= 2013-10-18 Vulnerability Laboratory ID (VL-ID): ==================================== 1117 Common Vulnerability Scoring System: ==================================== 8.3 Product & Service Introduction: =============================== Elite CMS is a web content management system made for the peoples who don`t have much technical knowledge of HTML or PHP but know how to use a simple notepad with computer keyboard. Elite CMS Pro is a successor of the eliteCMS . Elite CMS was made available free to public last year i.e. 2008. Since then i have received hundreds of appreciation email from the users of eliteCMS world wide. Some user of my eliteCMS want some more robust and powerful features. Due to the huge response from the users i have decided to write pro edition of eliteCMS. All new features in pro edition of the eliteCMS is based on the feedbacks and suggestions made by users of eliteCMS - The Lightweight CMS. Some users suggested that eliteCMS should have multilevel menu navigation with sub pages support, some suggested multiple web forms support for cms pages, some want more flexible and easy to understand template system. (Copy of the Homepage: http://elitecms.net/elitecmspro.php ) Abstract Advisory Information: ============================== The Vulnerability Laboratory Research Team discovered multiple vulnerabilities in the Elite-Graphix `ElitCMS` v1.01 web-application. Vulnerability Disclosure Timeline: ================================== 2013-10-18: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Elite Graphix Product: ElitCMS - Web Application 1.01 Exploitation Technique: ======================= Remote Severity Level: =============== Critical Technical Details & Description: ================================ 1.1 A remote sql injection web vulnerability is detected in the official Elite-Graphix `ElitCMS` v1.01 web-application. The vulnerability allows remote attackers to unauthorized inject own sql commands to compromise the application dbms. The vulnerability is located in the `page` value of the index.php file. Remote attackers are able to inject own sql commands in the page parameter GET method request to compromise the database management system or web-application. The issue is a classic order by sql injection vulnerability. Exploitation of the sql injection web vulnerability requires no user interaction or privileged application user account. Successful exploitation of the sql injection bug results in database management system and web-application compromise. Vulnerable Module(s): [+] Index Vulnerable File(s): [+] index.php Vulnerable Parameter(s): [+] page 1.2 A client-side post inject web vulnerability is detected in the official Elite Graphix ElitCMS v1.01 web-application. The vulnerability allows remote attackers to manipulate via POST method web-application to browser requests (client-side). The vulnerability is located in the contact form module of the application in the name value parameter. Remote attackers can inject own malicious persistent script codes as name value in the contact form when processing to send via POST method. The script code execute occurs in the thanks page in the context of the echo name value. Successful exploitation of the client-side POST inject web vulnerability results in session hijacking, client-side phishing, client-side unauthorized external redirects and client-side manipulation of the contact formular module context. Vulnerable Module(s): [+] Contact Formular Vulnerable File(s): [+] page Vulnerable Parameter(s): [+] name Proof of Concept (PoC): ======================= 1.1 The sql injection web vulnerability can be exploited by remote attackers without privileged application user account and also without user interaction.

Reference(s): http://elit.localhost:8080/elitecms/index.php?page=3 Solution - Fix & Patch: ======================= 1.1 The sql injection web vulnerability can be patched by the implement of a secure statement to the page value and index.php file. Also restrict the page value request and ensure the output is secure encoded. Disallow the display of sql debug/errors logs in the cms main context. Setup a own module to log sql errors in the acp. 1.2 The client-side post inject web vulnerability can be patched by a secure parse and encode of the name value in the post method request and the thanks page echo message. Security Risk: ============== 1.1 The security risk of the sql injection web vulnerability is estimated as critical. 1.2 The security risk of the client-side post inject web vulnerability is estimated as low(+)|(-)medium.
