  "details": "MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the AddressesTo parameter of /Mondo/lang/sys/Forms/AddressBook.aspx. The AddressesTo value is not properly sanitized when processed via a GET request and is reflected within a \u003cscript\u003e block in the response. By supplying a crafted payload that terminates the existing JavaScript 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.",
