Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in GFI Archiver versions before 15.13. An authenticated attacker can inject malicious scripts via the server URL parameter in the IMAP Server configuration page. The payload is stored without proper encoding and later executed when other users view the configuration page.

Detection Guidance

To detect this vulnerability, check if your GFI Archiver version is before 15.13. Inspect the IMAP Server configuration page for unusual scripts in the server URL parameter. Review the ImapServerWizard.aspx file for improper output encoding in the SaveAllConfigSettings() function.

Impact Analysis

If exploited, this vulnerability could allow attackers to execute arbitrary scripts in the context of a user's browser session. This may lead to session hijacking, theft of sensitive data, or unauthorized actions on behalf of the user.

Compliance Impact

Stored XSS vulnerabilities can compromise data confidentiality and integrity, which may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations must address this to maintain compliance.

Mitigation Strategies

Immediately update GFI Archiver to version 15.13 or later. Remove any suspicious scripts from the IMAP Server configuration page. Ensure proper output encoding is applied to user inputs in the ImapServerWizard.SaveAllConfigSettings() function.
