      "value": "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."

      "value": "Froxlor es software de administración de servidor de código abierto. Antes de la versión 2.3.8, el comando API DomainZones.add en lib/Froxlor/Api/Commands/DomainZones.php acepta valores de registro y tipo controlados por el usuario sin rechazar delimitadores de línea, caracteres de tabulación, puntos y coma o tipos de registro DNS no compatibles antes de que lib/Froxlor/Dns/DnsEntry.php serialice los valores en un archivo de zona BIND. Un cliente autenticado con permisos de zona DNS puede colocar un valor manipulado en el campo de registro, o usar la variante de campo de tipo relacionada, para crear líneas de registro de recursos adicionales que eluden la validación a nivel de campo de Froxlor. BIND acepta los registros inyectados, permitiendo la modificación de datos DNS y un posible impacto en la disponibilidad de DNS dentro de una zona que el llamador está autorizado a administrar. Este problema se solucionó en la versión 2.3.8."
