CyberRota Analysis

AI-Generated

DataEase versions prior to 2.10.26 are vulnerable due to multiple access control flaws in the sharing link module, allowing attackers to reuse valid tickets across different shares and bypass mandatory ticket checks. This can lead to unauthorized modifications, deletions of tickets, and enumeration of other users' share mappings, potentially resulting in denial of service and data exposure. Organizations using affected versions should prioritize patching to mitigate these security risks.

Original NVD Description

DataEase before 2.10.26 contains multiple access control defects in the sharing link module. Tickets are not bound to the target share UUID, so a valid ticket issued for one share can be reused against another (ShareTicketManage.validateTicket / POST /de2api/share/proxyInfo). The POST /de2api/share/validate endpoint issues a LinkToken after password verification without requiring a ticket, bypassing the 'ticket mandatory' policy. Additionally, the ticket create and delete endpoints (POST /de2api/ticket/saveTicket, POST /de2api/ticket/delTicket) lack share-ownership checks, allowing an authenticated user who knows another user's ticket to modify, rebind, or delete it (denial of service), and GET /de2api/share/queryRelationByUserId/{uid} allows authenticated users to enumerate other users' share mappings.
