Impact
froxlor versions before 2.2.5 fail to validate newline characters in subdomain redirect URLs, allowing authenticated customers to inject arbitrary nginx or Apache configuration directives. Attackers can supply URLs containing literal newlines that are written verbatim into vhost config files during cron rebuild, enabling web server configuration corruption, denial of service, or hijacking of HTTP responses across hosted domains.
