Abstract

Embodiments of the present invention provide a text configuration file-oriented fuzz testing method and device, the method comprising: identifying the text file format type of the target configuration file, and determining the key-value pair of the target configuration file; Carry out pre-fuzz test to the program that uses described target configuration file as input to detect whether described program has the loophole on format, and extract all visible character strings in described program, to the key-value pair of described target configuration file The key in the key is mutated to obtain the key combination seed file; based on the weight of the key in the key combination seed file, the value corresponding to the key in the key combination seed file is mutated to obtain a new combination seed file, and the program bugs. The embodiment of the present invention realizes comprehensively digging deeper loopholes in programs, and improves the efficiency of fuzzy testing for text configuration files.

Description

technical field [0001] The invention relates to the field of loophole mining and analysis, in particular to a fuzzy testing method and device for text configuration files. Background technique [0002] Fuzz testing is a technology that exploits vulnerabilities in software or systems in a dynamic way. The fuzz testing tool is represented by AFL. Its concept is dynamic execution and path coverage improvement. The general implementation method is to use the seed file as the input to actually execute the test program, and at the same time record the execution path corresponding to each seed file by means of instrumentation, and then Try to mutate the seed file, so that the mutated seed file can be used as program input to allow the program to go through different execution paths. [0003] In the prior art of fuzz testing, the input types are often varied, which can be network data input through sockets, or reading input from program command line parameters, or directly from the...
