Deserialization of Untrusted Data in Apache Hadoop YARN

High severity GitHub Reviewed Published Aug 26, 2022 to the GitHub Advisory Database • Updated Jan 28, 2023

Package

maven org.apache.hadoop:hadoop-yarn-server (Maven)

Affected versions

< 2.10.2
>= 3.0.0, < 3.2.4
>= 3.3.0, < 3.3.4

Patched versions

2.10.2
3.2.4
3.3.4

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. Users should upgrade to Apache Hadoop 2.10.2, 3.2.4, 3.3.4 or later (containing YARN-11126) if ZKConfigurationStore is used.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
