[原文]Multiple cross-site scripting (XSS) vulnerabilities in Kamgaing Email System (kmail) 2.3 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) d parameter to main.php, ordner parameter to (2) main.php, or (3) webdisk.php, (4) draft parameter to compose.php, or (5) m, or (6) y parameter to calendar.php.
Kmail contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'id' and 'ordner' variables upon submission to the main.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.
