High severity GitHub Reviewed Published Jun 8, 2023 in snowflakedb/snowflake-connector-net • Updated Nov 6, 2023

Package

nuget Snowflake.Data (NuGet)

Affected versions

< 2.0.18

Patched versions

2.0.18

Description

Issue

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

Impacted driver package:

snowflake-connector-net

Impacted version range:

before Version 2.0.18

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 December 2nd, 2022, Snowflake merged a patch that fixed a command injection vulnerability in the Snowflake .NET driver via SSO URL authentication. The vulnerability affected the Snowflake .NET driver before Version 2.0.18. We strongly recommend upgrading to the latest driver version as soon as possible via the following resources: Snowflake .NET Driver.

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.
