Summary

Snowflake Connector for .NET has race condition when checking access to Easy Logging configuration file

Details

Issue

Snowflake discovered and remediated a vulnerability in the Snowflake Connector for .NET (“Connector”). When using the Easy Logging feature on Linux and macOS, the Connector didn’t correctly verify the permissions of the logging configuration file, potentially allowing an attacker with local access to overwrite the configuration and gain control over logging level and output location.

This vulnerability affects Connector versions 2.1.2 through 4.4.0. Snowflake fixed the issue in version 4.4.1.

Vulnerability Details

When using the Easy Logging feature on Linux and macOS, the Connector reads logging configuration from a user-provided file. On Linux and macOS, the Connector verifies that the configuration file can be written to only by its owner. That check was vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition and failed to verify that the file owner matches the user running the Connector. This could allow a local attacker with write access to the configuration file or the directory containing it to overwrite the configuration and gain control over logging level and output location.

Solution

Snowflake released version 4.4.1 of the Snowflake Connector for .NET, which fixes this issue. We recommend users upgrade to version 4.4.1.
