Abstract

The invention discloses a program vulnerability detection method. The method comprises the following steps: when a target source code of a target program is obtained, obtaining a vulnerability initial node set and a control flow diagram based on the target source code; obtaining a vulnerability executable path set based on the vulnerability initial node set and the control flow diagram; analyzing vulnerability executable paths in the vulnerability executable path set to obtain a vulnerability analysis result; based on the vulnerability analysis result, obtaining a vulnerability detection result of the target program. The invention further discloses a program vulnerability detection device, terminal equipment and a computer readable storage medium. By utilizing the vulnerability detection method of the program, the technical effect of improving the vulnerability detection efficiency of the program is achieved.

Description

technical field [0001] The present invention relates to the technical field of program detection, in particular to a program vulnerability detection method, device, terminal equipment and computer-readable storage medium. Background technique [0002] With the development of information technology, the number and types of programs are increasing, and at the same time, the loopholes in the programs are also increasing. Software vulnerabilities refer to flaws in the logic design of the program, or errors in the process of programming; illegal users can use software vulnerabilities to steal important information, and even use software vulnerabilities to obtain system privileges, and then perform various illegal operations. At present, the research focus of program vulnerability detection is how to detect vulnerabilities, how to describe characteristic leaks and how to locate vulnerabilities. [0003] In related technologies, a program vulnerability detection method is proposed...
