Affected versions

>= 3.6.8, <= 3.21.0

Patched versions

Description

Issue

Snowflake discovered and remediated a vulnerability in the Snowflake JDBC Driver. On Linux systems, when temporary credential caching is enabled, the Snowflake JDBC Driver will cache temporary credentials locally in a world-readable file.

This vulnerability affects versions 3.6.8 through 3.21.0. Snowflake fixed the issue in version 3.22.0.

Vulnerability Details

On Linux, when either EXTERNALBROWSER or USERNAME_PASSWORD_MFA authentication methods are used with temporary credential caching enabled, the Snowflake JDBC Driver will cache temporary credentials in a local file. In the vulnerable versions of the Driver, this file is created with world-readable permissions.

Solution

Snowflake released version 3.22.0 of the Snowflake JDBC Driver, which fixes this issue. We recommend users upgrade to version 3.22.0.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
