Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in Apache Superset versions before 4.1.2, where the configurable dictionary DISALLOWED_SQL_FUNCTIONS, designed to restrict execution of sensitive SQL functions, had an incomplete default list for the ClickHouse engine.
Because of this incomplete restriction, potentially sensitive SQL functions could be executed in SQL Lab and charts when using ClickHouse, bypassing intended security controls.
How can this vulnerability impact me? :
The impact of this vulnerability is that users of Apache Superset with the ClickHouse engine could execute sensitive SQL functions that were supposed to be blocked.
This could lead to unauthorized data access or manipulation within SQL Lab and charts, potentially exposing sensitive information or affecting data integrity.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
