What is a difference between an SQL injection and a cross-site scripting attack?

While both attacks can lead to user information compromise, the description 'intercepts user information' for SQLi and 'causes false or unpredictable results' for XSS does not accurately describe their fundamental technical difference in attack mechanism.

SQL injection exploits vulnerabilities in an application's database interactions by injecting malicious SQL code into input fields, thereby modifying the database query executed. Cross-Site Scripting (XSS) involves injecting malicious client-side scripts into web pages viewed by other users, often by encoding HTML or script tags to evade input validation and sanitization filters.

'SQL injection detects environments' is an inaccurate description of SQL injection; its primary purpose is data manipulation or extraction through query modification. 'XSS cloaks by encoding tags' is partially correct for XSS but paired with an incorrect SQLi description.

XSS attacks manipulate the client-side browser context and do not typically grant access to server-side files beyond the web root; this type of access is generally associated with directory traversal or other server-side vulnerabilities.
