How Do Hackers Exploit Software Vulnerabilities?

Introduction

Every day in India, banks lose crores, websites get defaced, and user data leaks because of simple software bugs. Our 8,000+ placed students at Ethical Hacking Training Institute & Webasha Technologies legally exploit real buffer overflows, SQL injections, RCE, and zero-days every single day in lab. They then patch the same flaws for Deloitte, EY, Paytm, PhonePe, Indian banks, and global companies while earning ₹20 to 70 LPA packages within months of training.

Top 10 Software Vulnerabilities Hackers Exploit Most in 2025

• Buffer Overflow & Stack Overflow (memory corruption)
• SQL Injection (classic and blind)
• Cross-Site Scripting (XSS: reflected, stored, DOM)
• Remote Code Execution (RCE)
• Insecure Deserialization (Java, .NET, Python pickle)
• Command Injection / OS Command Injection
• Path Traversal / Directory Traversal
• Server-Side Request Forgery (SSRF)
• Insecure Direct Object Reference (IDOR)
• XML External Entity (XXE) attacks

Real Exploitation Techniques We Teach in Lab

• Buffer overflow with ROP chain and shellcode
• SQLi bypass WAF + time-based blind extraction
• XSS to full account takeover + cookie stealing
• RCE via file upload, Log4Shell, deserialization gadgets
• SSRF to internal AWS metadata + cloud takeover
• Command injection to reverse shell
• XXE to internal file read and SSRF combo
• IDOR to mass data leak

Students perform 100+ real exploits every month on licensed vulnerable apps.

Our Exact Exploitation Lab Setup (2025)

• 100+ deliberately vulnerable web apps (DVWA, WebGoat, Juice Shop, custom banking apps)
• Windows & Linux buffer overflow labs with Immunity Debugger
• Licensed Burp Suite Pro + Nessus + Cobalt Strike
• Real deserialization labs (ysoserial, PHPGGC, Java gadgets)
• Log4Shell, Spring4Shell, Text4Shell environments
• Weekly new CVE-based vulnerable machines
• Active Directory + Kerberoasting + Golden Ticket labs

Only institute in India with full exploitation and patching lab.
