CVE-2024-3795Network attack vector

Session-data theft via stored template-field script

Published Apr 15, 2024 · Updated Aug 8, 2024

Stored cross-site scripting in White Bear Solutions WBSAirback 21.02.04 allows remote authenticated users to steal session data. The /admin/BackupTemplate handler stores the name and description fields without neutralizing script content, which executes when a victim opens the affected administrative view. High-privilege access is required to plant the payload, and a victim must interact with the crafted content; the reported consequence is session-data theft.
