Summary
Snowflake JDBC Security Advisory
Impacted Products
Snowflake JDBC driver versions >= 3.2.6 & <= 3.19.1 are affected.
Introduction
Snowflake recently identified an issue affecting JDBC drivers that can result in data being uploaded to an encrypted stage without the additional layer of protection provided by client side encryption. The issue, which affects only a subset of accounts hosted on Azure and GCP deployments (AWS deployments are not affected), manifests in instances where customers create a stage using a JDBC driver with the CLIENT_ENCRYPTION_KEY_SIZE account parameter set to 256-bit rather than the default 128-bit. The data is still protected by TLS in transit and server side encryption at rest. This missed layer of the additional protection is not visible to the affected customers.
Incorrect Security Setting Vulnerability
Description
Snowflake identified an incorrect security setting in Snowflake JDBC drivers. Snowflake has evaluated the severity of the issue and determined it was in medium range with a maximum CVSSv3 base score of 5.9.
Scenarios and attack vector(s)
Users of Snowflake JDBC drivers with accounts on Azure and GCP deployments who set the parameter CLIENT_ENCRYPTION_KEY_SIZE = 256 were subject to this incorrect security setting vulnerability as it could result in data being uploaded to a stage without an additional layer for encryption.
Our response
On July 23, 2024, Snowflake discovered this vulnerability. On 10/28/2024, Snowflake released a patch in Snowflake JDBC driver Version 3.20.0. The patch fixes the incorrect security setting.
Resolution
We strongly recommend users to upgrade to 3.20.0 or later versions as soon as possible.

Impact
CVE-2024-43382 has a CVSS score of 5.9 (Medium). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (3.20.0); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2024-43382? CVE-2024-43382 is a medium-severity security vulnerability in net.snowflake:snowflake-jdbc (maven), affecting versions >= 3.2.6, <= 3.19.1. It is fixed in 3.20.0.
- How severe is CVE-2024-43382? CVE-2024-43382 has a CVSS score of 5.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of net.snowflake:snowflake-jdbc are affected by CVE-2024-43382? net.snowflake:snowflake-jdbc (maven) versions >= 3.2.6, <= 3.19.1 is affected.
- Is there a fix for CVE-2024-43382? Yes. CVE-2024-43382 is fixed in 3.20.0. Upgrade to this version or later.
- Is CVE-2024-43382 exploitable, and should I be worried? Whether CVE-2024-43382 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-43382 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2024-43382? Upgrade
net.snowflake:snowflake-jdbcto 3.20.0 or later.
