https://notcve.org/view.php?id=CVE-2021-3618
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer. ALPACA es un ataque de confusión de contenido de protocolo de capa de aplicación, que explota servidores TLS que implementan diferentes protocolos pero que usan certificados compatibles, como certificados multidominio o comodín. Un atacante de tipo MiTM que tenga acceso al tráfico de la víctima en la capa TCP/IP puede redirigir el tráfico de un subdominio a otro, resultando en a una sesión TLS válida. • https://alpaca-attack.com https://bugzilla.redhat.com/show_bug.cgi?id=1975623 https://lists.debian.org/debian-lts-announce/2022/11/msg00031.html • CWE-295: Improper Certificate Validation •
