yeah….😬

Can see why there haven’t been any sticky Twitter competitors

Super insane. Kinda scary, curious about the ramifications of violent games that look so realistic

It’d be an interesting read! Why not?

Bootstrapped businesses can’t play the same game that venture-backed businesses play

TLDR;

- In a bug bounty program (telecommunications company)
- Scanned their IPV4 Ranges
- Found a webserver that said "███ Cable System"
- Directory brute-force found /admin/accounts/
- The endpoint set a valid admin JSESSIONID

10/ I reported it immediately and started pinging their program manager.

It was the best response I've ever gotten.

And will ever get

9/ I clicked through the menus to see if I was actually authenticated.

I was. FULLY. AUTHENTICATED.

On that same IP range,

They had ANOTHER system for ANOTHER cable.

I tried the same attack.

IT WORKED!

I had admin access to TWO. Different. Cables.

I was in disbelief.

So,

8/ Redirected to the home page.

Second visit:

> HTTP/1.1 200 OK
> --- snip ---
> <title>Account Administration</title>

HOLY **** IT WORKED.

This is a HIGHLY redacted version of what I saw:

So,

7/ It's probably worthless. Right?

I was intrigued enough.

So I decided to visit the endpoint in my browser.

Twice.

1st - To set the JSESSIONID cookie in my browser.
2nd - To see if the cookie was valid & used for authentication.

1st visit: http://<IP>/admin/accounts/ and

6/ Let's see if there are more directories down /admin/

Directory-Bruteforcing found /accounts/.

This redirected to the login page.

I was about to brute-force JSP files when I realized something unique in the response.

A header.

> Set-Cookie: JSESSIONID=<id>;

That's weird.

5/ The directory /admin/

Remember, it's running Apache Tomcat.

I built a wordlist for .jsp files using BigQuery. (Learned from @assetnote's commonspeak)

Bruteforcing found a few JSP files, but they all redirected to the login page.

Gah. Well,

4/ "login.jsp"

Ok! It was a Tomcat webserver

I didn't have credentials. Obviously.

I started with directory brute-forcing.

Used @joohoi's ffuf & filtered by the number of response words on the 404 page.

It found several directories.

One that stuck out was

3/ "███ Cable System" (I have to redact this)

So, I visited the server in my browser.

The home page said

> "Welcome to the ███ Management System"

No way. This isn't really online is it?
Underneath was a link:

"Log in to ███"

Clicked it and it brought me to

2/ I searched the company's name on bgp.he\.net

Saved their IP ranges.

I ran masscan, probed for HTTP(s) servers, and grabbed the HTTP titles.

Looked something like:

$ masscan -p 80,443 -iL ranges -oL out.txt
$ cat out.txt | httpx -title

One title stuck out:

1/ It began with a bug bounty program.

Of a telecommunications company (that I can't name publicly).

As some of you may know, I love recon.

I had already done subdomain enumeration.

The next step was to scan their IP ranges.

So,
