A Fuzz Testing Approach for Embedded Avionic Software

The objective of the research was to find if it was possible to apply fuzz testing, a technique that can be used to test software to discover vulnerabilities, on an embedded avionic software using an open-source fuzz tool. The open-source fuzz tool AFL++ was applied to an NH90 Airbus Helicopter embedded software component to find the vulnerabilities. The proposed setup was able to find a few crashes related to data parsing associated with Ada strong typing declaration requirement. Moreover, the experiments outline practical guidelines and considerations for implementing fuzz testing on embedded avionic software.
