CVE-2023-39265 in Superset
Summary
by MITRE • 09/06/2023
Apache Superset would allow for SQLite database connections to be incorrectly registered when an attacker uses alternative driver names like sqlite+pysqlite or by using database imports. This could allow for unexpected file creation on Superset webservers. Additionally, if Apache Superset is using a SQLite database for its metadata (not advised for production use) it could result in more severe vulnerabilities related to confidentiality and integrity. This vulnerability exists in Apache Superset versions up to and including 2.1.0.

Apache Superset version 2.1.0 contains a critical vulnerability that allows attackers to manipulate SQLite database connection registration through alternative driver names such as sqlite+pysqlite or by leveraging database import mechanisms. This flaw stems from insufficient validation of database connection parameters during the registration process, creating an avenue for unauthorized file system interactions on the Superset web server. The vulnerability specifically affects systems where attackers can influence the database connection string or import process, potentially enabling them to create unexpected files in the web server's file system. When Apache Superset is configured to use SQLite for its metadata storage, which is not recommended for production environments, the impact becomes significantly more severe as it could compromise both confidentiality and integrity of the system. The issue is particularly concerning because it allows for arbitrary file creation on the web server, which could be exploited to establish persistence or escalate privileges within the system. This vulnerability aligns with CWE-22 Improper Limitation of a Pathname to a Restricted Directory, as it enables path traversal and unauthorized file system access through improper database connection handling. The flaw exists due to inadequate input validation and sanitization of database connection strings, allowing attackers to inject alternative driver names that bypass normal security checks. According to ATT&CK framework, this vulnerability maps to T1059 Command and Scripting Interpreter and T1078 Valid Accounts, as it could enable attackers to execute commands through file creation and potentially gain access to valid system accounts. The risk is amplified when Superset is configured with SQLite metadata storage, as this creates additional attack surface for information disclosure and data manipulation attacks. Organizations using Apache Superset versions up to 2.1.0 should immediately implement mitigations including restricting database connection parameters, implementing strict input validation, and upgrading to patched versions. The vulnerability demonstrates a critical weakness in the application's database connection handling mechanism and represents a significant security risk for any system where attackers can influence database configuration parameters. This flaw could be exploited by attackers to create malicious files in the web server's file system, potentially leading to further system compromise through code execution or privilege escalation. The security implications extend beyond simple file creation to encompass potential data breaches and system integrity violations, particularly when SQLite metadata storage is in use. Organizations should consider implementing network segmentation, monitoring for unusual file creation patterns, and restricting database connection capabilities to minimize the impact of this vulnerability. The vulnerability underscores the importance of proper input validation and parameter sanitization in database connection handling processes, as inadequate controls can lead to severe operational security consequences.
