Stored XSS via CSRF-triggered email setting
Published Sep 9, 2024 · Updated Sep 9, 2024
Stored XSS in Snapshot Backup 2.1.1 and earlier allows remote attackers to inject script through an administrator's browser. The snapshot-automation handler accepts snapshot_auto_email from a POST request without a CSRF token, sanitization, or output escaping, then stores it. Exploitation requires a logged-in administrator to open attacker-controlled HTML; the stored script executes when the value is rendered.
