Multiple cross-site scripting (XSS) vulnerabilities in PhpAuction 2.5 allow remote attackers to inject arbitrary web script or HTML via the lan parameter to (1) index.php or (2) admin/index.php, or (3) the auction_id parameter to profile.php. NOTE: there is evidence that viewnews.php and login.php may not be part of the PhpAuction product, so they are not included in this description.
Improper Neutralization of Input During Web Page Generation The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
