Detailsinfo

A vulnerability was found in snowflakedb snowflake-connector-net up to 4.4.0 on Linux/macOS. It has been rated as problematic. This issue affects an unknown part of the component Easy Logging. The manipulation with an unknown input leads to a toctou vulnerability. Using CWE to declare the problem leads to CWE-367. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state. Impacted is confidentiality. The summary by CVE is:

snowflake-connector-net is the Snowflake Connector for .NET. Versions starting from 2.1.2 to before 4.4.1, are vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition. 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 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. This issue has been patched in version 4.4.1.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2025-46326 since 04/23/2025. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
