Froxlor is open source server administration software. Prior to version 2.3.6, accepts arbitrary DNS record types without a whitelist and does not sanitize newline characters in the field. When a DNS type not covered by the if/elseif validation chain is submitted (e.g., , , ), content validation is entirely bypassed. Embedded newline characters in the content survive processing, are stored in the database, and are written directly into BIND zone files via . An authenticated customer can inject arbitrary DNS records and BIND directives ( , , ) into their domain's zone file. Version 2.3.6 fixes the issue.
