This vulnerability allows the Snowflake JDBC Driver to cache temporary credentials in a world-readable file on Linux systems when temporary credential caching is enabled. This poses a risk of unauthorized access to sensitive information stored in these credentials.
The severity of this vulnerability is classified as medium, with a CVSS score of 4.4. Organizations must understand the potential risks associated with this vulnerability, especially regarding credential exposure and unauthorized access.
As of now, there is no known public exploit associated with this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) database. However, given the nature of the vulnerability, organizations should prioritize patching immediately.
The fixed version is 3.22.0, and organizations using affected versions 3.6.8 through 3.21.0 should upgrade to mitigate risks effectively.
The urgency for defenders is moderate. Organizations should address this issue in their priority patch cycle to protect against potential credential exposure.
Vulnerability Details
Snowflake JDBC provides a JDBC type 4 driver that supports core functionality, allowing Java programs to connect to Snowflake. On Linux systems, when temporary credential caching is enabled, the Snowflake JDBC Driver will cache temporary credentials locally in a world-readable file. This vulnerability affects versions 3.6.8 through 3.21.0. Snowflake fixed the issue in version 3.22.0.
The vulnerability is classified under CWE-276: Incorrect Default Permissions. The CVSS base score of 4.4 indicates a medium severity, with the following metrics: attack vector (LOCAL), attack complexity (LOW), privileges required (LOW), and user interaction (NONE).
Technical Analysis
The root cause of this vulnerability is related to improper management of permissions on cached credential files. When the Snowflake JDBC Driver stores temporary credentials in a world-readable file, it exposes sensitive information to any local user.
The attack vector is local, as an attacker would need access to the system where the JDBC Driver is running. The attack complexity is low, requiring minimal effort to exploit the vulnerability once access to the system is obtained.
No user interaction is required to exploit this vulnerability, and it can lead to low confidentiality and integrity impacts, with no availability impact.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information due to the exposure of cached temporary credentials. This could lead to data breaches or further exploitation of the system.
The blast radius potential is significant, as the vulnerability could affect all users with access to the affected systems. Organizations must assess their risk exposure and prioritize remediation strategies.
Given the CVSS score, organizations should address this vulnerability in their priority patch cycle, particularly if they are utilizing versions 3.6.8 through 3.21.0 of the Snowflake JDBC Driver.
