Describe JSP security vulnerabilities and their prevention.
Some common JSP security vulnerabilities and prevention measures include:
- Cross-Site Scripting (XSS): Prevent XSS attacks by validating and sanitizing user input, encoding output to prevent script execution, and using frameworks or libraries that offer built-in protection against XSS, such as JSTL
<c:out>tag or OWASP’s Java Encoder library. - SQL Injection: Avoid SQL injection by using prepared statements or parameterized queries instead of concatenating user input directly into SQL statements. Implement input validation and parameter sanitization to prevent malicious input from being executed as SQL queries.
- Directory Traversal: Protect against directory traversal attacks by enforcing strict input validation and limiting access to authorized directories. Use security measures such as input sanitization and proper file path handling to prevent unauthorized file access.
