CVE-2026-30932Public exploitNetwork attack vector

DNS manipulation via unvalidated record-content newlines

Published Mar 24, 2026 · Updated Mar 24, 2026

BIND zone-file injection in Froxlor before 2.3.5 allows remote authenticated users to alter DNS data via crafted records. DomainZones.add accepts newline-bearing LOC, RP, SSHFP, and TLSA content, and DnsEntry::__toString() writes it directly into a BIND zone file. Customer access with DNS management enabled is required; injected directives can disclose BIND-readable files, add arbitrary records, or prevent a zone from loading.
