# HTP '13
# Congratulations, you're reading the source.
#
# Subzero v2 is a do-it-yourself Subzero v1. Some details have been provided throughout the source hinting at the potential usage.
# As far as changes, the Null RDS 1day has been removed, as well as the locale + FCKEditor exploitation checks & auth bypass + shell drop.
# If you know what you are doing, this 0day can be used in conjunction with the other 0days to exploit ColdFusion 6-10. (aka everything).
#
# ColdFusion 6 can be taken out with the locale 0day, and XORing password.properties against the stored private key will yield the actual
# login password.
#
# Since you're reading the source, we'll give you another 0day to improve Subzero. Once Subzero has extracted the hash, use scheduled tasks
# to store your backconnect shell in a temp directory (such as the CF temp directory/windows TEMP dir or /dev/shm). Then, use Server Settings
# > Settings in the CF admin to load it as the Missing Template Handler (you can travel upwards from the 'relative path' using ../). Finally,
# trigger a 404 to recieve your backconnect, and restore the Missing Template Handler. We might release fUZE Shell v2 in the future for POCs
# of this written in CFML.
#
# For anyone looking to fully weaponize Subzero into direct RXE for ColdFusion 10, we'll give you a hint. Subzero is a LFI, not a LFD.
# (preinstalled *.cfm) :P
