CVE-2022-41137
Description
A flaw was found in the Apache Hive Metastore (HMS). This vulnerability allows remote code execution (RCE) via deserialization of arbitrary data when the SerializationUtilities#deserializeObjectWithTypeInformation method filters and fetches partitions without additional input validation. In real deployments, the vulnerability can be exploited only by authenticated users/clients who successfully establish a connection to the Metastore. From an API perspective, any code that calls the unsafe method may be vulnerable unless it performs additional rechecks on the input arguments.
Statement
The Metastore component is used to stores the structure information of tables and partitions in the warehouse, meaning this issue impacts mainly the integrity and availability of the system.
Mitigation
Any code that calls the unsafe method may be vulnerable unless it performs additional checks on the input arguments. Implementing additional validations on input arguments before passing them to the SerializationUtilities#deserializeObjectWithTypeInformation method might mitigate or decrease this risk.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
