Full access to SQL injection vulnerabilities-article (1) with the development of B/S application development, more and more programmers are using this mode to write applications. However, due to the low entry threshold in this industry, the programmer's level and experience are also uneven. a considerable number of programmers did not judge the legitimacy of user input data when writing code, application se

Vulnerability overviewThe SQL injection vulnerability may occur in the following situations:1. Data enters the program from an untrusted data source.2. Data is used to dynamically construct an SQL query. The code is as follows:Copy code String userName = ctx. getAuthenticatedUserName ();String itemName = request. getParameter ("itemName ");String qu

Label:I. Introduction to SQL injection SQL injection is one of the most common methods of network attack, it is not to exploit the bugs of the operating system to implement the attack, but to neglect the programmer's programming, to realize the login without account and even tamper with the database through

Modsecurity is an intrusion detection and blocking engine that is primarily used for Web applications so it can also be called a Web application firewall. It can be run as a module of the Apache Web server or as a separate application. The purpose of modsecurity is to enhance the security of Web applications and protect Web applications from known and unknown attacks. This paper mainly introduces the idea of a penetration testing competition for open source WAF.1. Article backgroundModsecurity

5. Limit the input lengthIf you use a text box on a Web page to collect data entered by the user, it is also a good practice to use the MaxLength property of the text box to restrict the user from entering too long characters, because the user's input is not long enough to reduce the likelihood of pasting a large number of scripts. Programmers can make a corresponding throttling policy for the types of data that need to be collected.6.URL Rewriting TechnologyWe use URL rewriting techniques to fi

Security testing is a process in which confidential data is kept confidential and users can only perform operations within the authorized scope. For example:A confidential content is not exposed to unauthorized individuals or user entitiesUser B cannot unilaterally block a function of the website. What are the security testing aspects? SQL Injection (SQL

After the test, I can continue my penetration journey. Last night, Lucas sorted out the documents of the information security competition in Chengdu this summer. It seems that this is the first time that the competition was held overnight since the first day of the freshman year. The ISCC competition ended on the 10th. It should be okay to go to the Beijing Green League finals during the summer vacation. So during this time, I made a lot of exercises for WEB penetration and Buffer OverFlow, main
