CVE-2024-27315 in Superset
Summary
by MITRE • 02/28/2024
An authenticated user with privileges to create Alerts on Alerts & Reports has the capability to generate a specially crafted SQL statement that triggers an error on the database. This error is not properly handled by Apache Superset and may inadvertently surface in the error log of the Alert exposing possibly sensitive data.
This issue affects Apache Superset: before 3.0.4, from 3.1.0 before 3.1.1.
Users are recommended to upgrade to version 3.1.1 or 3.0.4, which fixes the issue.

The vulnerability CVE-2024-27315 represents a critical security flaw in Apache Superset that stems from inadequate error handling mechanisms within the alerting subsystem. This issue specifically targets authenticated users who possess the privilege to create alerts through the Alerts & Reports functionality, creating a significant attack surface that could be exploited by malicious actors with legitimate access to the system. The vulnerability manifests when users craft specially designed SQL statements that deliberately trigger database errors, which then propagate through the application's error handling mechanisms without proper sanitization or obfuscation.
The technical flaw resides in the improper handling of database error messages within Apache Superset's alert processing pipeline. When a crafted SQL statement executes and generates an error, the system fails to properly sanitize or filter the error output before logging it to the alert error logs. This oversight allows potentially sensitive information contained within database error messages to be exposed to authenticated users who have access to the alert error logs. The vulnerability is categorized under CWE-209, which specifically addresses "Information Exposure Through an Error Message," and aligns with ATT&CK technique T1211 for "Exploitation for Defense Evasion" as attackers could use this information to refine subsequent attacks against the database infrastructure. The error messages may contain database schema information, table names, column details, or other metadata that could aid in further exploitation attempts.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with valuable reconnaissance data that could be leveraged for more sophisticated attacks. Database error messages often contain detailed information about the underlying database structure, which could be used to craft more effective SQL injection attacks or to map out database schemas for targeted exploitation. The vulnerability affects multiple versions of Apache Superset, specifically all versions before 3.0.4 and versions 3.1.0 through 3.1.0, creating a window of opportunity for attackers to exploit this weakness in organizations that have not yet upgraded their systems. This exposure particularly impacts organizations using Superset for business intelligence and data visualization, where the system often has access to sensitive corporate data, making the potential for data leakage significantly more severe.
Organizations should prioritize immediate remediation by upgrading to Apache Superset version 3.1.1 or 3.0.4, which contain the necessary patches to address the improper error handling mechanism. The fix implemented in these versions ensures that database error messages are properly sanitized before being logged, preventing sensitive information from being exposed through alert error logs. System administrators should also implement additional monitoring of error logs to detect any potential exploitation attempts and consider implementing network-level controls to limit access to sensitive alert functionality. The mitigation strategy should include regular security assessments of the alerting subsystem and implementation of principle of least privilege controls to minimize the potential impact of compromised accounts. Organizations should also consider implementing database activity monitoring solutions that can detect and alert on suspicious SQL statement patterns that might indicate attempts to exploit this vulnerability, as outlined in the ATT&CK framework's emphasis on monitoring for suspicious activities that could indicate compromise.
