Technical details
A stored cross-site scripting (XSS) vulnerability exists in GFI Archiver versions prior to 15.13. The flaw is located in the Retention Policy configuration wizard, specifically within the 'policy name' parameter handled by /Archiver/RetentionPolicyWizard.aspx. The application's SaveAllConfigSettings() function fails to perform proper output encoding before storing the input. An authenticated attacker with network access to the management interface can inject a malicious payload that executes in the context of any user who subsequently views the Retention and Spam Policies page. This issue was addressed in version 15.13.
