CVE-2026-41230
No affected components available
Froxlor is open source server administration software. Prior to version 2.3.6, DomainZones::add() accepts arbitrary DNS record types without a whitelist and does not sanitize newline characters in the content field. When a DNS type not covered by the if/elseif validation chain is submitted (e.g., NAPTR, PTR, HINFO), content validation is entirely bypassed. Embedded newline characters in the content survive trim() processing, are stored in the database, and are written directly into BIND zone files via DnsEntry::__toString(). An authenticated customer can inject arbitrary DNS records and BIND directives ($INCLUDE, $ORIGIN, $GENERATE) into their domain's zone file. Version 2.3.6 fixes the issue.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the integrity of the data. There is a low impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
