User control not validating

Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications.

XSS enables attackers to inject client-side scripts into web pages viewed by other users.

Cross-site scripting attacks are a case of code injection.

A classic example of a potential vector is a site search engine: if one searches for a string, the search string will typically be redisplayed verbatim on the result page to indicate what was searched for.

If this response does not properly escape or reject HTML control characters, a cross-site scripting flaw will ensue.

Exploiting one of these, attackers fold malicious content into the content being delivered from the compromised site.

When the resulting combined content arrives at the client-side web browser, it has all been delivered from the trusted source, and thus operates under the permissions granted to that system.
