kandi X-RAY | people-against-security-lab Summary
This was a final exam project for CSCI-5460 - Network and Information Security. The assignment was to design a lab suitable for Undergraduate Computer Science students to complete in 4-6 hours that demonstrated something important in the area of security. The goal of this lab is to give students a basic understanding of how seemingly minor vulnerabilities in web applications can come together to cause major problems. The vulnerabilities covered in this lab are:. My goal was to give a practical overview of how these concepts could be applied, rather than going into the complexities that are more common in real life. Please note: This application is the total opposite of a good example of secure web development practices. It should only be used for it's intended purpose. That is, to teach others about the importance of security throughout a web application.

QUESTION
I have not, but shall DAST* security test, out of curiosity, an IoT device; Nodemcu esp8266 www server I built. It's showing a HTML page (on a mobile phone for example) that allows to control and interact with a camera module and a A/C relay. With it I can for example show images captured in the camera I even think it has some image recognition built in, and I can switch on and off a relay for electrical current to a light bulb (110/220v A/C power)
Before I start pentest I though I better start thinking of what types of exploits one would be able to find and detect? Which sinister exploits I will be able to find, or rather ought be able to find given a proper pentest exercise? (And if I do not find exploits, my approach to the pentest of the Iot might be wrong)
I ponder it might be a totally pointless exercise since the esp8266 www server (or rather its LUA programming libraries) might not have any security built into it, so basically it is "open doors" and everything with it is unsafe ?
The test report might just conclude what I can foresee be that the the "user input needs to be sanitized"?
Anyone have any idea what such pentest of a generic IoT device generally reports? Maybe it is possible to crash or reset the IoT device? Buffer overruns, XXS, call own code ?
I might use ZAP or Burpsuite or similar DAST security test tool.
- I could of course SAST test it instead, or too, but I think it will be hard to find a static code analyzer for the NodeMCU libraries and NUA scripting language easily ? I found some references here though: https://ieeexplore.ieee.org/abstract/document/8227299 but it seems to be a long read.
So if someone just have a short answer what to expect in a DAST scan/pentest , it would be much appreciated.
Stay safe and secure out there ! Zombieboy
...ANSWER
Answered 2021-Apr-08 at 01:04I do my vulnerability scanning with OpenVAS (I assume this is what you mean by pentesting?). I am not aware of any IOT focused Tools.
If your server is running on esp8266, i would imagine that there is no much room for authentication and encryption of http traffic, but correct me if i am wrong).
Vulnerability Scan results might show things like unencrypted http traffic, credentials transmitted in cleartext (if you have any credentials fields in the pages served by the web server) etc. Depending on if there is encryption, you might also see weak encryption findings.
You might get some false positives on your lua webserver reacting like other known webservers when exploits are applied. I have seen this kind of false positive specially on DoS vulnerabilities when a vulnerability scan is testing a vulnerability and the server becomes unresponsive. Depending on how invasive your vulnerability scanner is, you might get a lot of false positives for DoS on such a constrained platform.

Install people-against-security-lab
Test it before distributing to students Make sure you have the proper dependencies installed Ruby 2.1 bundler - gem install bundler Sqlite3 In a terminal, cd to the project directory. bundle install - Installs project dependencies bundle exec rake test - Runs the test suite If there are no errors, you should be good to go. Unless you chose to enhance the difficulty of password cracking. Then, you should run the application rackup, retrieve the generated passwords from pas.db that was just created, and determine that these hashes can be cracked with the information you have chosen to provide. If there are errors, they need to be resolved or your students may have problems.
Distribute the application to students using your preferred medium. bundle exec rake build Automatically includes wordlist.txt into the gem Required to generate passwords for the fake users Creates a self-contained gem in pkg/ that should be distributed to students "zip, 7z, tar.gz, etc." pkg/people_against_security.x.y.z.gem wordlist.txt If you want to make password cracking more difficult, this would be the simplified version of wordlist.txt setup.sh This configures a fresh Kali Linux installation (likely in a VM) to run PAS. Example: zip -r pas-lab.zip pkg/people_against_security.x.y.z.gem wordlist.txt setup.sh Send it to students along with a copy of doc/lab-instructions.docx. This includes instructions to setup PAS as well as the requirements for the lab.
