Abstract
Provided are a method and a system capable of efficiently detecting security vulnerability of program. The method includes: generating binary information including route information indicating an execution route of a program on a first test case; acquiring first crash information including the first test case and the route information when a crash of the first test case occurs; restoring a control flow graph based on the binary information; calculating complexity of the restored control flow graph; determining whether the complexity is less than a threshold value; only when a result of the determination indicates that the complexity is less than a threshold value, performing: executing a route detection on the route information; generating a second test case by executing the route detection; and acquiring a second crash information including the second test case and the route information.
