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.
