Technical details
The edit_recs.cgi script in the bind8 module outputs raw DNS record values without HTML entity encoding in ALL view mode. An attacker with delegated zone permissions can craft DNS records containing JavaScript payloads that persist in the zone file and execute in an administrator's browser session, potentially leading to session hijacking or administrative action takeover. A fix is available in newer versions.
