Vulnerability Disclosure Timeline: ================================== 2016-04-05: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Eight Webcom Product: Eight Webcom - AJAX (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 Eight Webcom web-application (2016 Q2). The vulnerability allows remote attackers to execute own sql commands to compromise the web-applicaation or connected dbms. The sql-injection vulnerability is located in the `id` and `newsid` values of the `content.php`file. Remote attackers are able to execute sql commands by injection of malicious statements via GET method request. The vulnerability is located on the application-side of the online service. The injection point is the id value in the vulnerable content.php file. The security vulnerability is a classic order by sql injection bug in the id parameter. The security risk of the sql-injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.1. Exploitation of the remote sql injection web vulnerability requires no user interaction or privileged web-application user accounts. 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): [+] content.php Vulnerable Parameter(s): [+] id Proof of Concept (PoC): ======================= The remote sql-injection web vulnerability can be exploited by remote attackers without user interaction or privileged web-application user accounts.
