CVE-2023-2666Network attack vector

Service interruption via unthrottled HTTP requests

Published May 12, 2023 · Updated Jan 24, 2025

Resource exhaustion in Froxlor before 2.0.16 allows remote attackers to interrupt the service by flooding HTTP endpoints. Each session could send unlimited panel, API, or installer requests because those entry points performed no request-count check before processing. Network access to a deployed web interface is sufficient; sustained requests can exhaust server resources and interrupt availability.
