Scan for SIP devices using OPTIONS requests

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

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/sip/options_tcp
msf auxiliary(options_tcp) > show options
    ... show and set options ...
msf auxiliary(options_tcp) > set RHOSTS ip-range
msf auxiliary(options_tcp) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(options_tcp) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(options_tcp) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(options_tcp) > set RHOSTS file:/tmp/ip_list.txt

Required Options

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

Knowledge Base

Vulnerable Application

SIP is a signaling protocol for voice, and video typically associated with VOIP and typically used in commercial phone systems. SIP and VOIP are gaining popularity with home and cellular voice/video calling systems as well.

This module scans the TCP port to identify what OPTIONS are available on the SIP service.

Verification Steps

  1. Start msfconsole
  2. Do: use auxiliary/scanner/sip/options_tcp
  3. Do: set rhosts [ip]
  4. Do: run

Scenarios

Cisco UC520

msf5 > use auxiliary/scanner/sip/options_tcp 
msf5 auxiliary(scanner/sip/options_tcp) > set rhosts 2.2.2.2
rhosts => 2.2.2.2
msf5 auxiliary(scanner/sip/options_tcp) > run

[*] 2.2.2.2:5060    - 2.2.2.2:5060 tcp SIP/2.0 200 OK: {"Server"=>"Cisco-SIPGateway/IOS-12.x", "Allow"=>"INVITE, OPTIONS, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIFY, INFO, REGISTER"}
[*] 2.2.2.2:5060    - Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed

Confirming using NMAP

Utilizing the sip-methods script

nmap --script=sip-methods -p 5060 2.2.2.2

Starting Nmap 7.70 ( https://nmap.org ) at 2018-10-11 15:44 EDT
Nmap scan report for 2.2.2.2
Host is up (0.0036s latency).

PORT     STATE SERVICE
