kandi X-RAY | libntlm2 Summary

libntlm2 is a C library typically used in Testing, Security Testing applications. libntlm2 has no bugs, it has no vulnerabilities and it has low support. However libntlm2 has a Non-SPDX License. You can download it from GitLab.

Libntlm2 is an implementation of the NTLM authentication protocol released under a dual BSD/LGPL license (see COPYING). It was written from scratch by Simon Josefsson following this documentation:. Testing made sure that it is fully backwards compatible with Libntlm. WARNING! Only use NTLM for interoperability purposes. The protocol provides weak security and is based on old cryptographical techniques. It is only marginally better than sending your password in the clear. Libntlm2 does not support all variants of NTLM. In fact, Libntlm2 only sends LM+NTLM responses. The LM response is weak, using only DES. The NTLM responses is stronger but still weak (MD4+DES). Note that both LM and NTLM responses are sent, thus the combined protocol is only as secure as LM (i.e., not at all). Libntlm2 does not support NTLM2 session responses nor NTLMv2. Libntlm2 does not support sending only the NTLM response, to avoid the weaknesses in the LM response. Supporting more variants would be fairly straight-forward to add if someone is interested.

DAST security scaning of a IoT Nodemcu esp8266 LUA script www HTML server connected to camera and A/C relay

QUESTION

DAST security scaning of a IoT Nodemcu esp8266 LUA script www HTML server connected to camera and A/C relay

Asked 2021-Apr-08 at 01:04

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

I 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.
