CVE-2023-34231

Issue

Snowflake was informed via our bug bounty program of a command injection vulnerability in the Snowflake Golang driver via SSO browser URL authentication.

Impacted driver package:

gosnowflake

Impacted version range:

before Version 1.6.19

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 21, 2023, Snowflake merged a patch that fixed a command injection vulnerability in the Snowflake Golang driver via SSO browser URL authentication. The vulnerability affected the Snowflake Golang driver before Version 1.6.19. We strongly recommend users upgrade to Version 1.6.19 as soon as possible via the following resources: Go Snowflake Driver
