This vulnerability allows files downloaded from stages to be temporarily placed in a world-readable local directory, making them accessible to unauthorized users on the same machine. The affected versions are 2.0.12 through 4.2.0 on Linux and macOS. Snowflake has addressed this issue in version 4.3.0.
The CVSS score for this vulnerability is 5, indicating a medium severity. The risk to organizations includes potential unauthorized access to sensitive data. Organizations should prioritize patching immediately.
Currently, there are no known exploits for this vulnerability, but it is essential for organizations to remain vigilant and apply the necessary updates to mitigate any potential risks.
Organizations using the affected versions are advised to update to version 4.3.0 or later to ensure security against this vulnerability.
Vulnerability Details
The Snowflake Connector for .NET has a vulnerability classified under CWE-276, which pertains to improper handling of temporary files. This issue can lead to unauthorized access, posing a significant risk to confidentiality.
The vulnerability was published on January 29, 2025, and has been analyzed thoroughly. The attack vector is local, and the privileges required to exploit this vulnerability are low, with user interaction required.
Technical Analysis
The root cause of this vulnerability stems from the way files are managed during the download process. They are saved in a directory that can be accessed by any user on the same system, increasing the risk of exposure.
The attack complexity is low, meaning it does not require advanced skills to exploit the vulnerability. Additionally, it involves local access, which implies that an attacker must have access to the machine running the affected software.
Organizations must ensure that appropriate controls are in place to limit unauthorized access to sensitive directories and monitor user activities that may indicate exploitation attempts.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive files stored on the same machine. The blast radius could extend to any user with access to the affected directory, leading to data breaches.
Given the confidentiality impact is classified as high, organizations must address this vulnerability as part of their immediate patching cycle. The urgency is further underscored by the existing CVSS score of 5.5, indicating the potential for significant negative consequences if exploited.
