【转】嘟嘟牛网吧系统GetShell

释放双眼,带上耳机,听听看~!
测试了下学校周围的两个网吧都成功了。理论通杀长沙所有嘟嘟牛。首先这个系统比较老。看文件最后修改时间是11年的,漏洞有很多,不知道有没有前辈分享过。注入漏洞的话限制很大,万一不是root,万一不能写shell万一路径变了呢。虽然我测试的那个两个网吧,mysql都是装在3308端口,默认密码应该也不会改

首先这个系统比较老。看文件最后修改时间是11年的,漏洞有很多,不知道有没有前辈分享过。

注入漏洞的话限制很大,万一不是root,万一不能写shell万一路径变了呢。

虽然我测试的那个两个网吧,mysql都是装在3308端口,默认密码应该也不会改,但是万一别的地方不一样呢。

所以我就终于找到了个利用更简单更稳定的上传getshell

先要用iisputscanner什么的扫下网吧网段,找到收银服务器,收银服务器开启了80和8080.

也没什么技术含量,就是简单的黑名单验证上传,也不需要登陆,直接构造表单上传个jspx就可以了。

path=….// ,过滤一个../还会剩下个../,我测试第二个网吧的时候,直接上传不了,这样子才上传成功。

然后这东西权限自然是炒鸡大的,不大的话,也能自己提上去嘛。上远控什么的:
