![]() ![]() On reversing that DLL, I’ll find a JSON derserialization issue, and exploit it to get file read and the user’s SSH key. I’ll abuse the first file read to get the DLL for that server. In that source, I see how it connects to the other. I’ll exploit a file read vulnerability to locate and retrieve the source. In Beyond Root, I’ll look at another easter egg challenge with a thank you message, and a YouTube video exploring the webserver and it’s vulnerabilities.Ĭtf htb-bagel hackthebox nmap python flask source-code file-read dotnet websocket ffuf source-code reverse-engineering proc wscat dnspy json json-deserialization dotnet-deserialization īagel is centered around two web apps. I’ll use database creds to pivot to the next user, and a kernel exploit to get to root. Once registered, I’ll enumerate the API to find an endpoint that allows me to become an administrator, and then find a command injection in another admin endpoint. It features a website that looks like the original HackTheBox platform, including the original invite code challenge that needed to be solved in order to register. It released directly to retired, so no points and no bloods, just for run. TwoMillion is a special release from HackTheBox to celebrate 2,000,000 HackTheBox members.

That site uses websockets to do a validation task. With this foothold, I’ll identify a second virtual host with a new site. On finding the default credentials, I’ll use that to upload a webshell and get a shell on the box. Soccer starts with a website that is managed over Tiny File Manager.

To get administrator, I’ll attack active directory certificate services, showing both certify and certipy. That user has access to logs that contain the next user’s creds. With those, I’ll use xp_dirtree to get a Net-NTLMv2 challenge/response and crack that to get the sql_svc password. I’ll start by finding some MSSQL creds on an open file share.

The specific tool to use for troubleshooting a blocked address bar is the Web Console. ![]() To access Firefox's developer tools, click on Tools in the toolbar, and select Web Developer. Web developer tools are a great way to get around blocked content, and in some cases, they can also help you get around blocked Wi-Fi access. This is great news for you, because you can access a website without an address bar via your web console and inserting window.location. Many paywall sites, Boingo or not, simply block the address bar so that you can't freely roam the web. The Backup Plan: Use Your Browser's Developer Tools Now, this Wi-Fi hack won't let you bypass the paywall for every Boingo Wireless hotspot in every airport, but that's okay, because there is an alternative measure that can be taken. Instead of clicking Get Online Now and forking over your credit card number to a heavily used network, you could simply click the little box that says The Good Stuff. ![]() Then you open your browser, waiting for unrestricted access (which never comes). When you first look for a Wi-Fi connection at an airport with Boingo, you notice an available and apparently free network connection. According to Reddit user CrowdSorceror, there's a weakness that can be exploited in their system to bypass the paywall. You'll find them in the world's largest airports, including JFK, Chicago O'Hare, Dallas/Fort Worth, Beijing, and Dubai. Unfortunately, there isn't much we can do about waiting, but this little Wi-Fi hack could help make the waiting a little less boring.īoingo is that Wi-Fi hotspot you excitedly find in certain airports ( and other places) before you realize they charge you for internet. Airports are terrible germ-infested purgatories where people sit around for hours without Wi-Fi while they anxiously await to get wherever they really want to go. ![]()
