List of CVEs: CVE-2019-12258

This module detects VxWorks and the IPnet IP stack, along with devices vulnerable to CVE-2019-12258.

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.

Stability:

  • crash-safe: Module should not crash the service.

Basic Usage

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

msf > use auxiliary/scanner/vxworks/urgent11_check
msf auxiliary(urgent11_check) > show options
    ... show and set options ...
msf auxiliary(urgent11_check) > set RHOSTS ip-range
msf auxiliary(urgent11_check) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(urgent11_check) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(urgent11_check) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(urgent11_check) > 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

This detects systems running vulnerable versions of the Interpeak IPnet TCP/IP stack, which may be exploitable due to bugs parsing malformed network packets which can lead to memory corruption or denial-of-service attack possibilities.

Verification Steps

  1. Do: use auxiliary/scanner/vxworks/urgent11_check
  2. Do: set [RHOSTS], replacing [RHOSTS] with a list of hosts to test for the presence of the vulnerable IP stack.
  3. Do: set [RPORTS], replacing [RPORTS] with a list of possible service ports to interrogate for vulnerable stack behavior.
  4. Do: run
  5. If the host is exposing an identifiable IPnet TCP/IP stack, it will print the endpoint and report a vuln.

Options

RPORTS Set to a comma or space-delimited list of ports to check for the vulnerability.

VERBOSE Set to see how the probabilities of a vulnerable host are calculated.

Scenarios

msf5 auxiliary(scanner/vxworks/urgent11_check) > set RHOSTS 192.168.86.1 192.168.86.2
RHOSTS => 192.168.86.1 192.168.86.2
msf5 auxiliary(scanner/vxworks/urgent11_check) > set THREADS 2
THREADS => 2
msf5 auxiliary(scanner/vxworks/urgent11_check) > set RPORTS 21 22 23 80 443
RPORTS => 21 22 23 80 443
msf5 auxiliary(scanner/vxworks/urgent11_check) > run
