SOCA Access Control System 180612 SQL Injection And Authentication Bypass


Vendor: SOCA Technology Co., Ltd
Product web page: http://www.socatech.com
Affected version: 180612, 170000 and 141007

Summary: The company's products include proximity and fingerprint access
control system, time and attendance, electric locks, card reader and writer,
keyless entry system and other 30 specialized products. All products are
attractively designed with advanced technology in accordance with users'
safety and convenience which also fitted international standard.

Desc: The Soca web access control system suffers from multiple SQL Injection
vulnerabilities. Input passed via multiple POST parameters is not properly
sanitised before being returned to the user or used in SQL queries. This
can be exploited to manipulate SQL queries by injecting arbitrary SQL code
and bypass the authentication mechanism. It allows the attacker to remotely
disclose password hashes and login with MD5 hash with highest privileges 
resulting in unlocking doors and bypass the physical access control in place.

Tested on: Windows NT 6.1 build 7601 (Windows 7 Service Pack 1) i586
           Windows NT 6.2 build 9200 (Windows Server 2012 Standard Edition) i586
           Apache/2.2.22 (Win32)
           PHP/5.4.13
           Firebird/InterBase DBMS
