Module Ranking and Traits


Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage


msf > use auxiliary/admin/http/telpho10_credential_dump
msf auxiliary(telpho10_credential_dump) > show targets
    ... a list of targets ...
msf auxiliary(telpho10_credential_dump) > set TARGET target-id
msf auxiliary(telpho10_credential_dump) > show options
    ... show and set options ...
msf auxiliary(telpho10_credential_dump) > exploit

Required Options


  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

Knowledge Base


Vulnerable Application


Telpho10 v2.6.31 (32-bit Linux ISO image download here).

Supporting documentation for this product can be found here.

Verification Steps


The following steps will allow you to install and dump the credentials from a Telpho10 instance:

  1. Download the Telpho10 ISO image and install in a VM (or on a system)
    • note that the ISO will default to a German keyboard layout
    • note that the ISO expects a SATA hard drive (not IDE/PATA) for installation
  2. configure the Telpho10's IP address
    • edit /etc/networks/interfaces accordingly
  3. Start msfconsole
  4. Do: use auxiliary/admin/http/telpho10_credential_dump
  5. Do: set RHOST <IP address of your Telpho10 instance>
  6. Do: run
  7. You should see a list of the retrieved Telpho10 credentials

Scenarios


Example output when using this against a Telpho10 v2.6.31 VM:
