CVE-2021-25642
ZKConfigurationStore which is optionally used by CapacityScheduler of Apache Hadoop YARN deserializes data obtained from ZooKeeper without validation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
ZKConfigurationStore which is optionally used by CapacityScheduler of Apache Hadoop YARN deserializes data obtained from ZooKeeper without validation. An attacker having access to ZooKeeper can run arbitrary commands as YARN user by exploiting this.
