Authenticated users of Microsoft Exchange and Java products should prioritize addressing this stored Cross-Site Scripting (XSS) vulnerability, which allows for the injection of persistent JavaScript or HTML content into the user management interface. The flaw, located in the "Microsoft Exchange mailbox" field, fails to properly validate input, enabling attackers to execute malicious scripts that can disrupt access to user properties and lead to a denial-of-service condition. While the severity is rated low, organizations should still mitigate this risk to maintain application integrity and user access.

Original NVD Description

DigitalCanion has discovered a stored Cross-Site Scripting (XSS) vulnerability that allows an authenticated malicious user to inject persistent JavaScript or HTML content, resulting in a denial-of-service condition within the web application. The specific flaw exists within the web portal listening on TCP port 443, under Configuration → Users → Users List. The vulnerability occurs in the “Microsoft Exchange mailbox” field, which fails to properly validate or sanitize user-supplied input before storing and rendering it. By injecting malicious JavaScript into this field, an attacker can cause the payload to execute whenever the affected user properties are accessed. This can prevent access to the affected user properties and result in a denial-of-service condition within the application's user-management functionality.
