Unauthenticated command execution via eval
Published Jul 13, 2023 · Updated Feb 13, 2025
acme.sh before 3.0.6 contains a code injection flaw that lets remote attackers execute arbitrary commands from a hostile server. The client passes server-provided data to shell eval without neutralization, so command text executes in the client context. The attack requires an ACME server response that reaches the client; successful exploitation can compromise confidentiality, integrity, and availability.
