Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in GFI Archiver versions before 15.13. It allows authenticated attackers to inject malicious scripts or HTML via the report name parameter in the MailInsights scheduled report configuration. The injected payload is stored without proper output encoding and executes when a user views the MailInsights page.

Detection Guidance

To detect this vulnerability, inspect GFI Archiver versions prior to 15.13 for stored XSS in MailInsights scheduled reports. Check the /Archiver/MailInsights.aspx endpoint for report names containing suspicious scripts. Review server logs for unauthorized report name modifications or unusual activity in the MailInsights page.

Impact Analysis

An attacker could steal session cookies, redirect users to malicious sites, or perform actions on behalf of the user. It requires authentication but can affect users who view scheduled reports.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, potentially violating GDPR (data protection) and HIPAA (health information privacy) by exposing personal or confidential information.

Mitigation Strategies

Upgrade GFI Archiver to version 15.13 or later to patch the vulnerability. If immediate upgrade is not possible, restrict access to the MailInsights.aspx endpoint and monitor for suspicious report configurations. Implement input validation for report names to prevent script injection.
