Occurs when users are allowed to insert unsafe inputs into a server-side template.

• A. Server-side Template Injection
• B. log injection attacks
• C. HTML Embedding
• D. LDAP Injection

Answer: (A)

Server-side Template Injection happens when user-supplied input is fed into a server-side template and the template engine evaluates that input. Template languages can execute code, access objects, or call functions as they render the page. If untrusted input is inserted directly into the template, an attacker can craft input that becomes part of the template logic, potentially leading to remote code execution, data exposure, or other server compromises. The takeaway is to avoid rendering user input as part of the template's executable surface, or to restrict and sanitize what the template engine can do—use proper escaping, sandboxed/template-limiting options, and strict input validation. Log injection attacks involve manipulating log data or formats, not rendering templates. HTML embedding refers to including content in HTML, which is different from server-side code execution within a template. LDAP Injection targets LDAP queries with crafted input, altering search filters or operations.
