The Snowflake Connector for Python stores sensitive data in logs

Moderate severity GitHub Reviewed Published Oct 24, 2024 in snowflakedb/snowflake-connector-python • Updated Oct 25, 2024

Package

pip snowflake-connector-python (pip)

Affected versions

< 3.12.3

Patched versions

3.12.3

Description

Issue

Snowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake.

These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3.

Vulnerability Details

When the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats.

Solution

Snowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

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.
