Problems solved by technology

[0005] The technical problem solved by the present invention is that the prior art uses a manual method to detect EL expression injection vulnerabilities, which requires relatively high skills and experience for security test engineers, which takes a lot of time, high time cost, and insufficient coverage. Comprehensive, inefficient, unable to meet the needs of batch and efficient detection of the website environment, and then provide an optimized EL expression injection vulnerability batch detection device and detection method

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0027] The invention relates to a batch detection method for EL expression injection vulnerabilities. Based on the Scrapy framework, the problems of low efficiency, time-wasting and high requirements for safety testers are solved in testing EL expression injection vulnerabilities.

[0028] The method includes the following steps.

[0029] Step 1: Collect URL files.

[0030] In the step 1, the collected URLs include URL files containing keywords or files containing manually imported URLs to be detected.

[0031] The URL file containing keywords is obtained by using a search engine to collect URLs containing keywords after inputting keywords or manually importing a keyword file.

[0032] The file containing the manually imported URL to be detected is obtained by manually inputting the absolute path ...

Abstract

The invention relates to an EL expression injection vulnerability batch detection device and method. A collection unit collects a URL file; a first response of a server is obtained based on a normal HTTP request; an HTTP request is sent based on an EL expression injection detection statement; a second response of the server is obtained; difference between the first response and the second responseis compared; and if the first response does not has an execution result of the detection statement and the second response exists, vulnerabilities exist, and a detection result is output and stored.According to the detection device and method, the requirement of batch vulnerability detection is met; the collection of a URL containing a keyword or the manual importing of files of URLs needing tobe detected is supported; the problems of low efficiency, time waste and high security tester requirements in testing the EL expression injection vulnerabilities are solved; the detection coverage rate is improved; the labor time cost is greatly reduced; the operation of a security tester is simplified; and the detection result is automatically generated for reference.

Description

technical field [0001] The present invention relates to the technical field of security devices for protecting computers, components, programs or data from unauthorized acts, and in particular to a batch detection device and detection method for EL expression injection vulnerabilities that improve detection coverage and reduce labor time costs . Background technique [0002] EL (Expression Language) provides a method to simplify expressions in JSP (Java Server Pages, java server pages), making it easier to write JSP. EL expressions are usually labels used to display data in the display layer in JSP. It can improve the coupling of pages. Because of its convenience and ease of use, it has been borrowed and developed by other frameworks. The two most common examples are OGNL (used by Struts) and SPEL (used by Spring). [0003] Because of the ease of use of EL expressions, EL expression injection vulnerabilities can also occur at any time. This vulnerability allows attackers to...
