Security Best Practices for PHP and Vue.js Development: Preventing Remote Execution of Privileged Commands

As web applications become more popular, it becomes critical to protect the security of the application and its user data. . In PHP and Vue.js development, preventing remote execution of privileged commands is a critical task. In order to ensure that our applications are not threatened by remote command execution, this article will introduce some best practices and code examples.

  1. Input Validation and Filtering
    A common entry point for remote command execution attacks is user input. Untrustworthy user input should always be considered a potential security threat. To prevent remote command execution, user input must be validated and filtered.

PHP example:

$user_input = $_GET['input'];
$clean_input = filter_var($user_input, FILTER_SANITIZE_STRING);

In this example, PHP's filter_var function is used to filter $user_input and only retain The content of string type. This ensures that user input does not contain dangerous commands.

Vue.js example:

data(){
  return{
    userInput: ''
  }
},
methods: {
  sanitizeInput(){
    // 使用合适的过滤函数对用户输入进行过滤
    this.userInput = this.userInput.replace(/(<([^>]+)>)/ig,"");
  }
}

The above example uses regular expressions to filter HTML tags in user input to prevent the injection of malicious code.

2. Parameter binding and preprocessing
During the process of interacting with the database, SQL injection is another common entry point for remote command execution. To prevent SQL injection attacks, parameter binding and prepared statements must be used.

PHP example:

$user_id = $_GET['id'];
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$stmt->bindParam(':id', $user_id, PDO::PARAM_INT);
$stmt->execute();

In this example, the prepare method of the PDO object is used to prepare the query statement and is bound through the bindParam method. The $user_id parameter entered by the user is determined. This prevents the injection of malicious code.

3. Principle of Least Privilege
When building a user permission system, the principle of least privilege should be followed: each user and each role can only have the minimum permissions required to perform their work.

PHP example:

if(is_admin()){
   // 执行管理员操作
}else{
   // 执行普通用户操作
}

In this example, according to the user's permissions, the corresponding code will be executed. This ensures that malicious users cannot execute privileged commands.

4. Use safe external command execution functions
In PHP, if external commands must be executed, you should try to use safe command execution functions and verify and filter the command parameters.

PHP Example:

$command = $_GET['command'];
$args = $_GET['args'];

// 验证和过滤命令参数
if(preg_match("/^[a-z0-9-]+$/i", $command) && preg_match("/^[a-z0-9-]+$/i", $args)){
  $output = shell_exec($command." ".$args);
  echo $output;
}else{
  echo "参数不合法";
}

In this example, regular expressions are used to validate commands and parameters. Commands are executed only if they match the expected format.

Summary:
Preventing remote execution of privileged commands is an important task in web application development. Remote command execution attacks can be effectively prevented by validating and filtering user input, using parameter binding and prepared statements, following the principle of least privilege, and using secure external command execution functions. Try to follow these best practices in your code to ensure application security and user data protection.
