LLDP – Link Layer Discovery Protocol Fuzzer

Use Netsparker


The first Link Layer Discovery Protocol Fuzzer is now available, test cases are also ready to be used along with the tool. The fuzzing architecure makes it easy to extend the tool with new test cases and more LLDP compliant devices arise.

LLDP is a Layer 2 protocol which allows network devices to advertise their identity and capabilities on the local network, it helps to keep track of devices and the packets are multi-casted.

CDP, EDP and NDP are similar to LLDP.

The LLDP fuzzer is meant for black box testing techniques on LLDP enabled networks/devices. Its aim is to find security vulnerabilities by using test cases as it’s important to be able to replicate a test case.

It can be automated and it tries to find bugs by sending malformed packets and look for corner cases.

It can find vulnerabilities in any agent receiving LLDP packets and is programmed in Python. It works fine on Linux but won’t work on Windows due to RAW socket limitations.

There are currently 10 test cases.

You can download LLDP Fuzzer here:

    Discovery Protocols are so silly. LLDP, and its proprietary sisters CDP and EDP, are all vulnerable by design. Now we have this great fuzzer to gather even more information on our target?!?! SWEET!!!!

    also NDP…
    U r right TRDQ, LLDP doesnt authenticate the packets.. which is not very smart…

    However, I guess its sort of a necessary evil though if you are trying to track inventory like with cysco or whatever.

    Yeah but these protocols could have been designed in a better way… I mean atleast packet authentication was something which shuld hv been taken care of…
