This documentation contains for example the location and description of found vulnerabilities. To be able to find and fix a vulnerability, developers have to check this documentation. We developed a tool-based semi-automated analysis approach to locate and fix security issues by recorded execution traces. For identifying the affected source code snippets in the project code, we determine the difference between a regular and a malicious execution trace. This difference is an indicator for a potential vulnerability. As case study for this analysis we use vulnerabilities, which enable remote code execution. We implemented this approach in a software prototype named FOCUS+. This tool visualizes the traces and differences by several views such as a method call graph view. All views facilitate direct access to affected code snippets and point to the possible vulnerabilities. Thus, identified security gaps can immediately be fixed in FOCUS+.
