Rockliffe MailSite Express WebMail Email Message Body XSS
Remote / Network Access
Loss of Integrity
MailSite Express contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the message body of incoming emails. This could allow a user to create a specially crafted email message that, when viewed, 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.
Upgrade to version 6.1.22 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
