We propose a solution in which the vulnerabilities drive an automated evolutionary computation repair process capable of directly patching embedded systems firmware. Our approach does not require access to source code, regression tests, or any participation from the software vendor. Instead, we present an interactive evolutionary algorithm that searches for patches that resolve target vulnerabilities while relying heavily on post-evolution difference minimisation to remove most regressions. Extensions to prior work in evolutionary program repair include: repairing vulnerabilities in COTS router firmware; handling stripped MIPS executable; operating without fault localisation information; operating without a regression test suite; and incorporating user interaction into the evolutionary repair process.
We demonstrate this method by repairing two well-known vulnerabilities in version 4 of NETGEAR's WNDR3700 wireless router before NETGEAR released patches publicly for the vulnerabilities. Without fault localisation we are able to find repair edits that are not located on execution traces. Without the advantage of regression tests to guide the search, we find that 80percent of repairs of the example vulnerabilities retain program functionality after minimisation. With minimal user interaction to demonstrate required functionality, 100percent of the proposed repairs were able to address the vulnerabilities while retaining required functionality.",
