Advisories for Pypi/Snowflake-Connector-Python package

Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the …

Issue Snowflake discovered and remediated a vulnerability in the Snowflake Connector for Python. A function from the snowflake.connector.pandas_tools module is vulnerable to SQL injection. This vulnerability affects versions 2.2.5 through 3.13.0. Snowflake fixed the issue in version 3.13.1. Vulnerability Details A function from the snowflake.connector.pandas_tools module is not sanitizing all of its arguments, and queries using them are not parametrized. An attacker controlling these arguments could achieve SQL injection by …

Issue Snowflake discovered and remediated a vulnerability in the Snowflake Connector for Python. The OCSP response cache uses pickle as the serialization format, potentially leading to local privilege escalation. This vulnerability affects versions 2.7.12 through 3.13.0. Snowflake fixed the issue in version 3.13.1. Vulnerability Details The OCSP response cache is saved locally on the machine running the Connector using the pickle serialization format. This can potentially lead to local privilege …

Issue Snowflake discovered and remediated a vulnerability in the Snowflake Connector for Python. On Linux systems, when temporary credential caching is enabled, the Snowflake Connector for Python will cache temporary credentials locally in a world-readable file. This vulnerability affects versions 2.3.7 through 3.13.0. Snowflake fixed the issue in version 3.13.1. Vulnerability Details On Linux, when either EXTERNALBROWSER or USERNAME_PASSWORD_MFA authentication methods are used with temporary credential caching enabled, the Snowflake …

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.

The Snowflake Connector for Python provides an interface for developing Python applications that can connect to Snowflake and perform all standard operations. Versions prior to 3.0.2 is vulnerable to command injection via single sign-on(SSO) browser 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 …

An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the snowflake-connector-python PyPI package, when an attacker is able to supply arbitrary input to the get_file_transfer_type method
