Strategies to deal with SQL injection vulnerabilities in PHP
Article Introduction:SQL injection is a common network attack method that uses the application's imperfect processing of input data to successfully inject malicious SQL statements into the database. This attack method is particularly common in applications developed using the PHP language, because PHP's handling of user input is usually relatively weak. This article will introduce some strategies for dealing with SQL injection vulnerabilities and provide PHP code examples. Using prepared statements Prepared statements are a recommended way to defend against SQL injection. It uses binding parameters to combine input data with

Example analysis of XML external entity injection vulnerability
Article Introduction:1. XML external entity injection XML external entity injection vulnerability is what we often call XXE vulnerability. XML is a widely used data transmission format, and many applications contain code for processing XML data. By default, many outdated or improperly configured XML processors will reference external entities. If an attacker can upload an XML document or add malicious content to the XML document, through vulnerable code, dependencies, or integrations, he or she can attack a flawed XML processor. The occurrence of XXE vulnerabilities has nothing to do with the development language. As long as the xml data is parsed in the application and the data is controlled by the user, the application may be vulnerable to XXE attacks. This article uses java

Struts2 vulnerability S2-001 example analysis
Article Introduction:Vulhub vulnerability series: struts2 vulnerability S2-0011. Vulnerability description: struts2 vulnerability S2-001 is when the user submits form data and verification fails, the server uses OGNL expression to parse the parameter value previously submitted by the user, %{value} and refills the corresponding form data. For example, in a registration or login page. If the submission fails, the server will usually default to returning the previously submitted data. Since the server uses %{value} to perform OGNL expression parsing on the submitted data, the server can directly send the payload to execute the command. 2. Vulhub vulnerability exploitation: Using vulhub to reproduce vulnerabilities can save the environment construction process, which is very convenient. vu
