The manipulation of the argument FieldCc with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79.

As an impact it is known to affect integrity. The summary by CVE is:

MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the FieldCc parameter of /Mondo/lang/sys/Forms/AddressBook.aspx. The FieldCc value is not properly sanitized when processed via a GET request and is reflected inside a <script> block in the JavaScript variable var CCFieldProvided. By supplying a crafted payload that terminates the existing LoadCurAddresses() function, inserts attacker-controlled script, and comments out remaining code, a remote attacker can execute arbitrary JavaScript in a victim’s browser when the victim attempts to send an email. Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user.
