[原文]Multiple cross-site scripting (XSS) vulnerabilities in phpCommunityCalendar 4.0.3 allow remote attackers to inject arbitrary web script or HTML via the (1) LoName parameter in (a) week.php and (b) month.php and (2) AddressLink parameter in (c) event.php.
phpCommunityCalendarcontains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the LoName variable upon submission to the week.php 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.
