[原文]Cross-site scripting (XSS) vulnerability in Calcium 3.10.1 allows remote attackers to inject arbitrary web script or HTML via the EventText parameter. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
Calcium contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'EventText' variable upon submission to the 'Calcium' script during the creation of a new 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 or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Disable the "HTML in Events" setting (enabled by default) on the "Display Settings" administration menu.
