Unauthenticated XSS in MapTiler Tileserver-php v2.0.
MapTiler Tileserver-php v2.0 is vulnerable to Cross Site Scripting (XSS). The GET parameter "layer" is reflected in an error message without html encoding. This leads to XSS and allows an unauthenticated attacker to execute arbitrary HTML or JavaScript code on a victim's browser.
echo 'Server: Unknown or not specified dataset "' . $tileset . '"';
