Summary

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. 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 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.

Risk Assessment

The vulnerability enables unauthorized access to shared resources, ticket manipulation, and enumeration of other users' data. This can lead to data confidentiality breaches, service disruptions, and privilege escalation.

Recommendation

Update DataEase to version 2.10.26 or later that includes fixes. Also review sharing configuration and ensure the 'ticket mandatory' policy is enforced.

Original NVD description (English source)

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.
