Summary

MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the Added parameter of /Mondo/lang/sys/Forms/MAI/AddRecipientsResult.aspx. The Added value is not properly sanitized when processed via a GET request and is reflected in the response, allowing an attacker to break out of existing markup and inject arbitrary script. A remote attacker can supply a crafted payload that closes an existing HTML list element, inserts attacker-controlled JavaScript, and comments out remaining code, leading to script execution in a victim's browser when the victim visits a malicious link.

Risk Assessment

Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user. This poses a risk to organizations using MailEnable, especially if users have access to the administrative panel.

Recommendation

Update MailEnable to version 10.54 or later. Additionally, consider implementing security headers (CSP) and training users to avoid suspicious links.
