Modified

Severity ?
8.2 (High) - CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:L/SA:N
CWE
  • CWE-636 - Not Failing Securely ('Failing Open')
  • CWE-757 - Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')
Summary
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.

CVE-2025-59432 (GCVE-0-2025-59432)
Vulnerability from cvelistv5
Published

Modified
2026-01-23 17:27
Severity ?
6.6 (Medium) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U
CWE
  • CWE-208 - Observable Timing Discrepancy
  • CWE-385 - Covert Timing Channel
Summary
SCRAM (Salted Challenge Response Authentication Mechanism) is part of the family of Simple Authentication and Security Layer (SASL, RFC 4422) authentication mechanisms. Prior to version 3.2, a timing attack vulnerability exists in the SCRAM Java implementation. The issue arises because Arrays.equals was used to compare secret values such as client proofs and server signatures. Since Arrays.equals performs a short-circuit comparison, the execution time varies depending on how many leading bytes match. This behavior could allow an attacker to perform a timing side-channel attack and potentially infer sensitive authentication material. All users relying on SCRAM authentication are impacted. This vulnerability has been patched in version 3.1 by replacing Arrays.equals with MessageDigest.isEqual, which ensures constant-time comparison.
