Injection
Injection flaws occur when an application sends hostile data to an interpreter. This includes SQL, NoSQL, OS command, ORM, LDAP, and Expression Language injection.
概要
Falls from #3 to #5 in 2025. Injection remains one of the most tested categories, covering issues from Cross-site Scripting (high frequency/low impact) to SQL Injection (low frequency/high impact).
攻撃者がこれを悪用する方法
攻撃パターンを理解することで、より優れた防御を構築できます。これらはセキュリティチームが監視する技術です。
SQL query manipulation
User input is incorporated into database queries without proper sanitization, allowing attackers to modify query logic or extract unauthorized data.
Command execution
User input flows into system commands, allowing attackers to execute arbitrary commands on the server.
Cross-site scripting (XSS)
User content is reflected or stored in web pages without encoding, allowing script execution in other users' browsers.
予防方法
- Use a safe API which avoids using the interpreter entirely
- Use parameterized queries or prepared statements
- Use positive server-side input validation
- Escape special characters for any residual dynamic queries
- Use LIMIT and other SQL controls to prevent mass disclosure
- Use Content Security Policy to mitigate XSS impact
