[原文]Multiple cross-site scripting (XSS) vulnerabilities in (1) start_page.css.php3 (aka start-page.css.php3) or (2) style.css.php3 in PHPMyChat 0.14.5 allow remote attackers to inject arbitrary web script or HTML commands via the FontName parameter. NOTE: it was later reported that 0.14.5 is also affected.
phpMyChat contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'FontName' variable upon submission to the 'start-page.css.php3' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
