Command injection vulnerability detected.

• Rule ID: java_lang_os_command_injection
• Languages: java
• Source: os_command_injection.yml

Description

Using external or user-defined input directly in an OS command can allow attackers to perform dangerous commands on the operating system.

Remediations

❌ Avoid using OS commands, with or without dynamic input, wherever possible. For example, look for an equivalent library or function to use instead.

✅ For dynamic input, rely on hardcoded values wherever possible

  String filePattern = "*.json";
  if request.getParameter("format") == "xml" {
    filePattern = "*.xml"
  }

  Process process = Runtime.getRuntime().exec("ls /myDir/" + extension);
