CVE-2021-38296 (GCVE-0-2021-38296)

Vulnerability from cvelistv5 – Published: 2022-03-10 08:20 – Updated: 2024-08-04 01:37

Title

Apache Spark Key Negotiation Vulnerability

Summary

Apache Spark supports end-to-end encryption of RPC connections via "spark.authenticate" and "spark.network.crypto.enabled". In versions 3.1.2 and earlier, it uses a bespoke mutual authentication protocol that allows for full encryption key recovery. After an initial interactive attack, this would allow someone to decrypt plaintext traffic offline. Note that this does not affect security mechanisms controlled by "spark.authenticate.enableSaslEncryption", "spark.io.encryption.enabled", "spark.ssl", "spark.ui.strictTransportSecurity". Update to Apache Spark 3.1.3 or later

Severity

No CVSS data available.
