CVE-2026-30932 Details
Description
Froxlor is open source server administration software. Prior to version 2.3.5, the DomainZones.add API endpoint (accessible to customers with DNS enabled) does not validate the content field for several DNS record types (LOC, RP, SSHFP, TLSA). An attacker can inject newlines and BIND zone file directives (e.g. $INCLUDE) into the zone file that gets written to disk when the DNS rebuild cron job runs. This issue has been patched in version 2.3.5.
A vulnerability in Froxlor's DomainZones.add API endpoint, prior to version 2.3.5, allows for BIND zone file injection. The endpoint, accessible to customers with DNS management enabled, failed to properly validate the content field for several DNS record types, including LOC, RP, SSHFP, and TLSA. This oversight enabled attackers to inject newlines and BIND directives, such as $INCLUDE, into the zone file. When the DNS rebuild cron job executed, the injected content was written to disk, potentially leading to unauthorized file access or disruption of DNS services.
Users can update to Froxlor version 2.3.5, which includes the necessary validation for DNS record content. The update is available on the Froxlor GitHub Releases page.
