This section briefly introduces some basic programming points. compared with system security, php Security defense requires programmers to be more careful with the various parameters entered by users. PHP code security and XSS, SQL injection, and so on are very useful for the security of various types of websites, especially UGC (User Generated Content) websites, forums, and e-commerce websites, it is often the hardest hit area of XSS and SQL injectio

Vulnerability overviewApache struts is an open source project maintained by the Pachitea (Apache) Software Foundation, an open-source MVC framework for creating enterprise-class Java Web applications. An arbitrary code execution vulnerability exists in the Showcase application of the Struts 2.3.x series demonstrating the plug-in for Struts2 integrated struts 1. When your app uses Struts2 Struts1 plug-ins, it may cause untrusted input to pass into the Actionmessage class causing the command to ex

SQL Injection Defense Bypass--two code 01 background first, why URL encodingUsually if something needs to be coded, it means that something is not suitable for transmission. For URLs, coding is primarily to avoid ambiguity and confusion.For example, the URL parameter string uses the Key=value key value pair in such a way to pass the parameter, the key value pair is separated by the symbol, /?name=abcpwd=123 If your value string contains = or , then i

This is not true, and you still need to be sure that you are cautious when passing data to a stored procedure, or that you are doing it safely when you use ORM to customize a query.Parameterized queries are considered to be the most effective defense against SQL injection attacks. The current mainstream ORM framework is built-in support and is recommended for durable layer encapsulation in this way.The

Backdoor enabled Conditions After understanding the necessary conditions for backdoors, let's take a look at the scenarios under which these backdoors are enabled: 1. built-in services of the operating system;2. Network Protocol bundling;3. Software compiler production;4. Post-

"Minimum permission" Principle For network administrators, the "minimum permission" principle is very important. The principle of "minimum Permissions" is that common users should run various programs with the minimum permissions that can meet the operational task needs. Gene
