CVE-2024-39887: Apache Superset < 4.0.2 - SQL Injection

id: CVE-2024-39887

info:
  name: Apache Superset < 4.0.2 - SQL Injection
  author: iamnoooob,rootxharsh,pdresearch
  severity: medium
  description: |
    An SQL Injection vulnerability in Apache Superset exists due to improper neutralization of special elements used in SQL commands. Specifically, certain engine-specific functions are not checked, which allows attackers to bypass Apache Superset's SQL authorization. To mitigate this, a new configuration key named DISALLOWED_SQL_FUNCTIONS has been introduced. This key disallows the use of the following PostgreSQL functions- version, query_to_xml, inet_server_addr, and inet_client_addr. Additional functions can be added to this list for increased protection.
  impact: |
    Authenticated attackers can bypass SQL authorization to execute restricted database queries.
  remediation: |
    Users are recommended to upgrade to version 4.0.2, which fixes the issue.
