Everything About SQL Injection 💉

What is SQL Injection?
SQL Injection is a web vulnerability that lets attackers manipulate database queries. This can lead to unauthorized access, data leaks, or even full control of the system.

🔬Types of SQL Injection

1️⃣ Classic SQLi – Injecting raw SQL commands.
2️⃣ Blind SQLi – No errors, but the response changes.
3️⃣ Time-Based SQLi – Uses response delays to extract data.
4️⃣ Union-Based SQLi – Merges malicious queries with valid ones.
5️⃣ Out-of-Band SQLi – Exfiltrates data through DNS, HTTP, etc.

♦️Potential Impact
▫️Access & dump sensitive data
▫️Bypass login systems
▫️Alter or delete database entries
▫️Full system compromise

🔰Common Entry Points
▫️Login forms
▫️Search inputs
▫️Contact forms
▫️URL query parameters

Defense Strategies 🛡
✅ Use parameterized queries
✅ Validate & sanitize inputs
✅ Apply least privilege to DB accounts
✅ Monitor logs for anomalies
✅ Perform regular security audits
