Description
Froxlor from 0.10.0 before 2.3.15 contains a missing authorization vulnerability in the SubDomains.delete API command that allows authenticated customers to delete reseller-provisioned main domains by supplying a main domain id. Attackers can bypass the web UI restriction to remove domains, orphan vhost, DNS and subdomain records, and drive subdomains_used below zero to gain extra subdomain allowance.
