VxHunter

A ToolSet for VxWorks Based Embedded Device Analyses.

Readme in other languages: English, 简体中文

Firmware Analyze Tool

The firmware analyze tool is plugins written in Python, mainly used for analyze firmware loading address, fix function name with symbol table and etc.

supported reverse tool:

  • IDA Pro 7.x
  • Ghidra 9.x
  • Radare2

Tested firmware:

  • Schneider 140NOE77101 - Ethernet network TCP/IP module
  • Siemens SCALANCE-X208/SCALANCE-X216/SCALANCE-X308 - Siemens SCALANCE X Switch
  • Hirschmann PowerMICE - Industrial ETHERNET Switch

How to use VxHunter firmware tools in Ghidra

vxhunter_firmware_init.py

vxhunter_analysis.py

After execute vxhunter_firmware_init.py, we can use vxhunter_analysis.py script to analyze VxWorks firmware. This script will search hard coded accounts, compiled in services and some other info.

VxSerial Debugger - Beta

The serial debugger tool is written in Python and based on VxWorks command line, usually we can get that command line from VxWorks device using serial port.

The serial debugger tool using memory read/write command to inject debugger shellcode into targat system, the shellcode is dynamic generation by keystone-engine.

It's similar to inline hook, if target hit the breakpoint, it will jump to debugger shellcode and waiting for other debug command.

The serial debugger tool support functions:

  • Memory read/write function.
  • Conditional breakpoint, Python based conditional function, return True to break, False to keep running.
  • Task status viewer(stacks, register).
  • VxWorks struct viewer(netpool, clBlk, etc).

Example

This is an example script to debug CVE-2018-19528 vulnerability on TP-Link TL-WR886N-V7 deivce with Firmware V1.1.0.

VxHunter
A ToolSet for VxWorks Based Embedded Device Analyses.
Readme in other languages: English, 简体中文
Firmware Analyze Tool
The firmware analyze tool is plugins written in Python, mainly used for analyze firmware loading address, fix function name with symbol table and etc.
supported reverse tool:
  • IDA Pro 7.x
  • Ghidra 9.x
  • Radare2
Tested firmware:
  • Schneider 140NOE77101 - Ethernet network TCP/IP module
  • Siemens SCALANCE-X208/SCALANCE-X216/SCALANCE-X308 - Siemens SCALANCE X Switch
  • Hirschmann PowerMICE - Industrial ETHERNET Switch
IDA Demo
Ghidra Demo
How to use VxHunter firmware tools in Ghidra
vxhunter_firmware_init.py
vxhunter_analysis.py
After execute vxhunter_firmware_init.py, we can use vxhunter_analysis.py script to analyze VxWorks firmware.
This script will search hard coded accounts, compiled in services and some other info.

VxSerial Debugger - Beta
The serial debugger tool is written in Python and based on VxWorks command line, usually we can get that command line from VxWorks device using serial port.
The serial debugger tool using memory read/write command to inject debugger shellcode into targat system, the shellcode is dynamic generation by keystone-engine.
It's similar to inline hook, if target hit the breakpoint, it will jump to debugger shellcode and waiting for other debug command.
The serial debugger tool support functions:
  • Memory read/write function.
  • Conditional breakpoint, Python based conditional function, return True to break, False to keep running.
  • Task status viewer(stacks, register).
  • VxWorks struct viewer(netpool, clBlk, etc).
Example
This is an example script to debug CVE-2018-19528 vulnerability on TP-Link TL-WR886N-V7 deivce with Firmware V1.1.0.
