Mô tả CVE
SCRAM (Salted Challenge Response Authentication Mechanism) is part of the family of Simple Authentication and Security Layer (SASL, RFC 4422) authentication mechanisms. Prior to 3.3, a flaw in com.ongres.scram:scram-client and com.ongres.scram:scram-common allows an attacker capable of a TLS man-in-the-middle attack to silently downgrade a connection from SCRAM-SHA-256-PLUS with channel binding to standard SCRAM-SHA-256 without channel binding when TlsServerEndpoint processes an X.509 certificate using a modern signature algorithm such as Ed25519; getChannelBindingData() can return an empty byte array after NoSuchAlgorithmException, and the ScramClient builder treats that as absent channel-binding data. This issue is fixed in version 3.3.

Điểm yếu liên quan
| Tên điểm yếu | Nguồn | |
|---|---|---|
| Not Failing Securely When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions. |
||
| Selection of Less-Secure Algorithm During Negotiation A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used in a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties. |
