snowflakedb/snowflake-jdbc

A weakness has been identified in snowflakedb snowflake-jdbc up to 4.0.1. Impacted is the function SdkProxyRoutePlanner of the file src/main/java/net/snowflake/client/internal/core/SdkProxyRoutePlanner.java of the component JDBC URL Handler. Executing a manipulation of the argument nonProxyHosts can lead to inefficient regular expression complexity. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. This patch is called 5fb0a8a318a2ed87f4022a1f56e742424ba94052. A patch should be applied to remediate this issue.

Snowflake JDBC driver versions >= 3.2.6 and <= 3.19.1 have an Incorrect Security Setting that can result in data being uploaded to an encrypted stage without the additional layer of protection provided by client side encryption.

Snowflake JDBC provides a JDBC type 4 driver that supports core functionality, allowing Java program to connect to Snowflake. Users of the Snowflake JDBC driver were vulnerable to a command injection vulnerability. An attacker could set up a malicious, publicly accessible server which responds to the SSO URL with an attack payload. If the attacker then tricked a user into visiting the maliciously crafted connection URL, the user’s local machine would render the malicious payload, leading to a remote code execution. The vulnerability was patched on March 17, 2023 as part of Snowflake JDBC driver Version 3.13.29. All users should immediately upgrade the Snowflake JDBC driver to the latest version: 3.13.29.
