CVE-2024-5814

A malicious TLS1.2 server can force a TLS1.3 client with downgrade capability to use a ciphersuite that it did not agree to and achieve a successful connection. This is because, aside from the extensions, the client was skipping fully parsing the server hello. https://doi.org/10.46586/tches.v2024.i1.457-500

Summary		(es) Un servidor TLS1.2 malicioso puede obligar a un cliente TLS1.3 con capacidad de degradación a utilizar un conjunto de cifrado con el que no estuvo de acuerdo y lograr una conexión exitosa. Esto se debe a que, aparte de las extensiones, el cliente se saltaba por completo el análisis del saludo del servidor. https://doi.org/10.46586/tches.v2024.i1.457-500
