Summary

This check looks at user-supplied input in query string parameters and POST data to identify where certain HTML attribute values might be controlled. This provides hot-spot detection for XSS (cross-site scripting) that will require further review by a security analyst to determine exploitability.

Solution

Validate all input and sanitize output it before writing to any Javascript on* events.

Other Info

The page at the following URL: http://example.com/i.php?place=moon&name=Foo includes the following Javascript event which may be attacker-controllable: User-input was found in the following data of an [onerror] event: foo The user input was: foo
