ZKTeco ZKBioSecurity 3.0 Hardcoded Credentials Remote SYSTEM Code Execution

Title: ZKTeco ZKBioSecurity 3.0 Hardcoded Credentials Remote SYSTEM Code Execution
Advisory ID: ZSL-2016-5362
Type: Local/Remote
Impact: System Access
Risk: (5/5)
Release Date: 30.08.2016
Summary
ZKBioSecurity3.0 is the ultimate "All in One" web based security platform developed by ZKTeco. It contains four integrated modules: access control, video linkage, elevator control and visitor management. With an optimized system architecture designed for high level biometric identification and a modern-user friendly UI, ZKBioSecurity 3.0 provides the most advanced solution for a whole new user experience.
Description
The ZKBioSecurity solution suffers from a use of hard-coded credentials. The application comes bundled with a pre-configured apache tomcat server and an exposed 'manager' application that after authenticating with the credentials: username: zkteco, password: zkt123, located in tomcat-users.xml file, it allows malicious WAR archive containing a JSP application to be uploaded, thus giving the attacker the ability to execute arbitrary code with SYSTEM privileges.
