Abstract

The invention discloses a vulnerability detection method and device. The method comprises the steps that a source-code file of a target application is obtained, wherein the source-code file contains identification information of the target application; whether the identification information is stored in a database or not is found, and under the condition that the identification information is stored in the database, an original source-code file corresponding to the identification information is extracted from the database; whether the source-code file is identical to the original source-code file or not is judged, and if not, first source codes, different from those of the original source-code file, in the source-code file are obtained; the first source codes are matched with a prebuilt vulnerability fixing characteristic model, and vulnerabilities fixed by the first source codes are determined. By means of the vulnerability detection method and device, the technical problems that in the prior art, the vulnerability position and fixed vulnerability parameters cannot be effectively recognized, and accordingly more labor needs to be consumed for vulnerability analysis are solved.

Description

Technical field [0001] This application relates to the field of information security, and specifically to a method and device for vulnerability detection. Background technique [0002] In recent years, as more and more Internet applications have become open source, the probability of application vulnerabilities has also increased greatly. Manufacturers will also release new versions that include patches to launch vulnerabilities fixes for various applications. During the release of the new version, relevant personnel need to know the location and parameters of the vulnerabilities fixed by the new version to determine the security of the new version. [0003] However, most of the current technologies simply monitor the message on the patch page, download the patch on the corresponding page, and read the vulnerability description file to passively obtain some information about the vulnerability, and cannot effectively identify the location of the vulnerability and the vulnerability p...
