GFI Archiver before 15.13 contains a stored cross-site scripting vulnerability in the IMAP Server configuration that allows authenticated attackers to inject arbitrary web script or HTML via the server URL parameter to /Archiver/ImapServerWizard.aspx. The injected payload is stored by ImapServerWizard.SaveAllConfigSettings() without output encoding and is executed in the browsers of users who subsequently view the IMAP Server configuration page.
