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

Title
Snowflake Connector vulnerable to Command Injection
Summary
snowflake-connector-net, the Snowflake Connector for .NET, is vulnerable to command injection prior to version 2.0.18 via SSO URL authentication. In order to exploit the potential for command injection, an attacker would need to be successful in (1) establishing a malicious resource and (2) redirecting users to utilize the resource. The 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. This attack scenario can be mitigated through URL whitelisting as well as common anti-phishing resources. Version 2.0.18 fixes this issue.

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

Title
Snowflake Connector .NET does not properly check the Certificate Revocation List (CRL)
Summary
The Snowflake .NET driver provides an interface to the Microsoft .NET open source software framework for developing applications. Snowflake recently received a report about a vulnerability in the Snowflake Connector .NET where the checks against the Certificate Revocation List (CRL) were not performed where the insecureMode flag was set to false, which is the default setting. The vulnerability affects versions between 2.0.25 and 2.1.4 (inclusive). Snowflake fixed the issue in version 2.1.5.

Title
Snowflake Connector vulnerable to Command Injection
Summary
snowflake-connector-net, the Snowflake Connector for .NET, is vulnerable to command injection prior to version 2.0.18 via SSO URL authentication. In order to exploit the potential for command injection, an attacker would need to be successful in (1) establishing a malicious resource and (2) redirecting users to utilize the resource. The 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. This attack scenario can be mitigated through URL whitelisting as well as common anti-phishing resources. Version 2.0.18 fixes this issue.
