[原文]Cross-site scripting (XSS) vulnerability in H-Sphere 2.5.1 Beta 1 and earlier allows remote attackers to inject arbitrary web script or HTML via the (1) next_template, (2) start, (3) curr_menu_id, and (4) arid parameters in psoft/servlet/resadmin/psoft.hsphere.CP when using the mailman/massmail.html template_name.
H-Sphere contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'next_template', 'start', 'curr_menu_id' and 'arid' variables upon submission to the psoft.hsphere.CP 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.
