Hunting application-level logical errors

Abstract

Business applications are complex artefacts implementing custom business logic. While much research effort has been put in the identification of technical vulnerabilities (such as buffer overflows and SQL injections), application-level logic vulnerabilities have drawn relatively limited attention, thus putting the application's mission at risk. In this paper, we design, implement, and evaluate a novel heuristic application-independent framework, which combines static and dynamic analysis, input vector, and information extraction analysis, along with a fuzzy logic system, so as to detect and assert the criticality of application-level logic vulnerabilities in Java stand-alone GUI applications. © 2012 Springer-Verlag.
