Headline
GHSA-5w5m-pfw9-c8fp: Snowflake Python Connector vulnerable to Command Injection
Issue
Snowflake was informed via our bug bounty program of a command injection vulnerability in the Snowflake Python connector via SSO browser URL authentication.
Impacted driver package:
snowflake-connector-python
Impacted version range:
before Version 3.0.2
Attack Scenario
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.
Solution
On March 23rd, 2023, Snowflake merged a patch that fixed a command injection vulnerability in the Snowflake Python connector via SSO browser URL authentication. The vulnerability affected the Snowflake Python connector before Version 3.0.2. We strongly recommend users upgrade to Version 3.0.2 as soon as possible via the following resources: Snowflake Python Connector

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 are 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 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 3.0.2 contains a patch for this issue.
