Authentication Bypass by Capture-replay in Apache Spark
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.apache.spark:spark-core | < 3.1.3 | 3.1.3 |
| PyPI | pyspark | < 3.1.3 | 3.1.3 |
Details
As written in the advisory (Markdown source, shown as plain text).
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
