Detailsinfo

A vulnerability was found in Apache Spark up to 2.4.5. It has been classified as critical. This affects some unknown processing of the component RPC Handler. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In Apache Spark 2.4.5 and earlier, a standalone resource manager's master may be configured to require authentication (spark.authenticate) via a shared secret. When enabled, however, a specially-crafted RPC to the master can succeed in starting an application's resources on the Spark cluster, even without the shared key. This can be leveraged to execute shell commands on the host machine. This does not affect Spark clusters using other resource managers (YARN, Mesos, etc).

The weakness was released 06/23/2020 (Website). It is possible to read the advisory at spark.apache.org. This vulnerability is uniquely identified as CVE-2020-9480 since 03/01/2020. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 06/24/2020).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
