Apache Calcite Avatica JDBC driver
httpclient_implUnderstanding CVE-2022-36364
This vulnerability in the Apache Calcite Avatica JDBC driver allows an attacker to execute arbitrary code through a specific connection property.
What is CVE-2022-36364?
Apache Calcite Avatica JDBC driver creates HTTP client instances based on provided class names without verifying if the class implements the expected interface, potentially leading to code execution and rare cases of remote code execution.
The Impact of CVE-2022-36364
The vulnerability requires the attacker to control JDBC connection parameters and have a vulnerable class with the ability to execute code in the classpath. From version 1.22.0 onwards, the driver will verify that the class implements the expected interface.
