[原文]Multiple cross-site scripting (XSS) vulnerabilities in phpCommunityCalendar 4.0.3, and possibly earlier versions, allow remote attackers to inject arbitrary web script or HTML via the LocationID parameter to (1) thankyou.php or (2) day.php, font parameter to (3) calDaily.php, (4) calMonthly.php, (5) calMonthlyP.php, (6) calWeekly.php, (7) calWeeklyP.php, (8) calYearly.php, (9) calYearlyP.php, (10) day.php, or (11) week.php, or (12) CeTi, (13) Contact, (14) Description, (15) ShowAddress parameter to event.php, and other attack vectors.
phpCommunityCalendar contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate user-supplied input in multiple fields when adding an event. 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.
