Detailsinfo

A vulnerability was found in MailEnable up to 10.53 and classified as problematic. This issue affects the function LoadCurAddresses of the file /Mondo/lang/sys/Forms/AddressBook.aspx. The manipulation of the argument FieldBcc with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. The summary by CVE is:

MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the FieldBcc parameter of /Mondo/lang/sys/Forms/AddressBook.aspx. The FieldBcc value is not properly sanitized when processed via a GET request and is reflected inside a <script> block in the JavaScript variable var BCCFieldProvided. 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 during normal email composition. Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user.
