CVE-2026-54543

CVE-2026-54543 · Froxlor DomainZones.add allows DNS zone-file RR injection via record/type fields

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Froxlor is open source server administration software. Prior to 2.3.8, the DomainZones.add API command in lib/Froxlor/Api/Commands/DomainZones.php accepts user-controlled record and type values without rejecting line delimiters, tab characters, semicolons, or unsupported DNS record types before lib/Froxlor/Dns/DnsEntry.php serializes the values into a BIND zone file. An authenticated customer with DNS-zone permissions can place a crafted value in the record field, or use the related type-field variant, to create additional resource-record lines that bypass Froxlor's field-level validation. BIND accepts the injected records, allowing modification of DNS data and possible DNS availability impact within a zone the caller is authorized to manage. This issue is fixed in version 2.3.8.
