## Technical details

A stored cross-site scripting (XSS) vulnerability exists in GFI Archiver versions prior to 15.13. The flaw is located in the /Archiver/CategorizationPolicyWizard.aspx component, specifically within the SaveAllConfigSettings() function, which fails to perform adequate output encoding on the 'rule name' and 'email criteria' parameters. An authenticated attacker with access to classification rules can inject malicious payloads that are subsequently executed in the context of any user (typically an administrator) who views the Classification Rules page.
