Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] refer to figure 1 The first embodiment of the application software security vulnerability detection method of the present invention provides an application software security vulnerability detection method, and the application software security vulnerability detection method includes:

[0047] Step S10, compiling the application software into a preset intermediate language code text.

[0048] In the present invention, by compiling the application software to be detected into an intermediate language text, one statement of the obtained application software code contains one semantic meaning, which will not cause ambiguity, and the language strength is relatively thinner than high-level languages, and thicker than low-level languages, which is suitable for static applications Software security vulnerability detec...

Abstract

A method and system for detecting a security hole of application software, a device, and a computer-readable storage medium. The method comprises: compiling application software into a preset intermediate language code text (S10); obtaining a data association structure of the application software according to the code text (S20); backtracking to search for an external input point corresponding to a sensitive calling point according to a variable parameter of the sensitive calling point and the data association structure in the application software (S30); and if the external input point corresponding to the sensitive calling point is successfully found, determining the external input point as a security hole of the application software (S40). The method greatly improves the detection efficiency of a security hole of application software.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method and system for detecting application software security vulnerabilities. Background technique [0002] Existing application software vulnerability static detection schemes are usually based on rule scanning of Android smali (Android compiler) or java (computer programming language) source code, and judge the code of application software by using predefined regular or character string feature matching check methods. Is there a problem with the pattern. [0003] Because this kind of static scanning is not associated with the program context data, it is only detected according to the established rules, which is prone to false positives of a large number of security risks; moreover, the language granularity of the Android smali code is relatively fine, and one semantic needs to be expressed by multiple statements. When detecting security vulnerabilities ...
