# CyberHeroes

## Nmap

```
nmap 10.10.150.136 -p- -sS -sV

PORT   STATE SERVICE VERSION
22/tcp open  ssh     OpenSSH 8.2p1 Ubuntu 4ubuntu0.4 (Ubuntu Linux; protocol 2.0)
80/tcp open  http    Apache httpd 2.4.48 ((Ubuntu))
Service Info: OS: Linux; CPE: cpe:/o:linux:linux_kernel
```

With only port 80 open we browse to the root page for CyberHeros.

Running the web site through ZAP proxy with attack mode enabled reveals several pages. Viewing the response results for /login.html reveals a potential user name and password. We see the password is assigned the value [#undefined](#undefined "mention")[#undefined](#undefined "mention")RevereString".

![](/files/1arGcNK0F6uJhpaXvru2)

Using the command line we are able to reverse the string.

```bash
echo "<Password>" | rev
```

To reveal the correct password for the user h3ck3rBoi where, we can then grab the room flag.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://viperone.gitbook.io/pentest-everything/writeups/tryhackme/linux/cyberheroes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
