OSCP-like Intermediate real life based machine designed to teach the importance of understanding a vulnerability. SHOULD work for both VMware and Virtualbox.

Enumeration

we have ports:

  • 21
  • 22
  • 80
  • 139/445

let’s enumerate 139/445,

users: aeolus cronus

let’s see the anonymous share,

we have the user aeolus

let’s enumerate port 80:

but nothing from the gobuster and nikto

Exploitation

let’s try to do ssh bruteforce with aeolus,

  • It gives the password - sergioteamo

Privilege Escalation

no kernel exploit

found a service running on 8080, and also cronus is running the service, this account might have some information.

  • port forword the port to your localport
seems like a product

it needs creds:

let’s reuse the creds we already have

aeolus:sergioteamo

Let’s search for exploits and do in metasploit,
