Software security is crucial in every aspect of information technology. As today's software has become larger and more complex than ever before, software fault localization has become more time consuming and labor intensive accordingly. Consequently, a broad spectrum of software fault localization techniques are proposed and implemented. However, most of these techniques assume the existence of a...
This paper presents a new method, capable of automatically generating attacks on binary programs from software crashes. We analyze software crashes with a symbolic failure model by performing concolic executions following the failure directed paths, using a whole system environment model and concrete address mapped symbolic memory in . We propose a new selective symbolic input method...
This paper proposes to test web applications and generate the feasible exploits automatically, including cross-site scripting and SQL injection attacks. We test the web applications with initial random inputs by detecting symbolic queries to SQL servers or symbolic responses to HTTP servers. After symbolic outputs detected, we are able to generate attack strings and reproduce the results, emulating...
We present a simple framework capable of automatically generating attacks that exploit control flow hijacking vulnerabilities. We analyze given software crashes and perform symbolic execution in concolic mode, using a whole system environment model. The framework uses an end-to-end approach to generate exploits for various applications, including 16 medium scale benchmark programs, and several large...
