Vulnerability from cvelistv5 – Published: 2024-08-27 18:38 – Updated: 2024-08-27 19:21
VLAI?
Summary
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
