Hive

Hive creates a credentials file to a temporary directory in the file system with permissions 644 by default when the file permissions are not set explicitly. Any unauthorized user having access to the directory can read the sensitive information written into this file. Users are recommended to upgrade to version 4.0.1, which fixes this issue.

Use of Arrays.equals() in LlapSignerImpl in Apache Hive to compare message signatures allows attacker to forge a valid signature for an arbitrary message byte by byte. The attacker should be an authorized user of the product to perform this attack. Users are recommended to upgrade to version 4.0.0, which fixes this issue. The problem occurs when an application doesn’t use a constant-time algorithm for validating a signature. The method Arrays.equals() returns false right away when it sees that one of the input’s bytes are different. It means that the comparison time depends on the contents of the arrays. This little thing may allow an attacker to forge a valid signature for an arbitrary message byte by byte. So it might allow malicious users to submit splits/work with selected signatures to LLAP without running as a privileged user, potentially leading to DDoS attack. More details in the reference section.

Signing cookies is an application security feature that adds a digital signature to cookie data to verify its authenticity and integrity. The signature helps prevent malicious actors from modifying the cookie value, which can lead to security vulnerabilities and exploitation. Apache Hive’s service component accidentally exposes the signed cookie to the end user when there is a mismatch in signature between the current and expected cookie. Exposing the correct cookie signature can lead to further exploitation. The vulnerable CookieSigner logic was introduced in Apache Hive by HIVE-9710 (1.2.0) and in Apache Spark by SPARK-14987 (2.0.0). The affected components are the following: * org.apache.hive:hive-service * org.apache.spark:spark-hive-thriftserver_2.11 * org.apache.spark:spark-hive-thriftserver_2.12

Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Hive. The vulnerability affects the Hive JDBC driver component and it can potentially lead to arbitrary code execution on the machine/endpoint that the JDBC driver (client) is running. The malicious user must have sufficient permissions to specify/edit JDBC URL(s) in an endpoint relying on the Hive JDBC driver and the JDBC client process must run under a privileged user to fully exploit the vulnerability.  The attacker can setup a malicious HTTP server and specify a JDBC URL pointing towards this server. When a JDBC connection is attempted, the malicious HTTP server can provide a special response with customized payload that can trigger the execution of certain commands in the JDBC client.This issue affects Apache Hive: from 4.0.0-alpha-1 before 4.0.0. Users are recommended to upgrade to version 4.0.0, which fixes the issue.

Apache Hive Metastore (HMS) uses SerializationUtilities#deserializeObjectWithTypeInformation method when filtering and fetching partitions that is unsafe and can lead to Remote Code Execution (RCE) since it allows the deserialization of arbitrary data. In real deployments, the vulnerability can be exploited only by authenticated users/clients that were able to 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 prerechecks on the input arguments.
