6.5 MEDIUM

Network endpoint reachable with low complexity; PR:L because a valid share-link token is required; confidentiality-only data exposure with no integrity or availability impact and no scope change.

DescriptionCVE.org

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, a share mode chart data interface only validates that sceneId matches the resourceId in the link token and fails to validate whether tableId and field IDs in the request body belong to the shared resource, allowing an attacker with a valid share link token to replace dataset identifiers and retrieve unauthorized data through POST /de2api/chartData/getData. This issue is fixed in version 2.10.24.

AnalysisAI

Insecure Direct Object Reference in DataEase before 2.10.24 lets a holder of any valid share-link token retrieve arbitrary datasets by tampering with the request body. The share-mode chart endpoint POST /de2api/chartData/getData validates only that sceneId matches the resourceId bound to the link token, but never checks that the supplied tableId and field IDs belong to the shared resource, so an attacker can swap in identifiers for datasets they were never granted. …

Vulnerability AssessmentAI

Exploitation Exploitation requires possession of a valid DataEase share-link token (PR:L) - i.e., the target instance must have the share feature enabled and a link issued to the attacker or otherwise obtained by them; a fully unauthenticated outsider with no token cannot exploit it. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor CVSS 4.0 score is 7.1 (High) with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N - network reachable, low complexity, no attack requirements, but requiring low privileges (PR:L) in the form of a valid share-link token, and impacting confidentiality only (VC:H, no integrity or availability effect). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An organization shares a single DataEase chart with an external partner via a share link. The partner (or anyone who obtains that link token) sends POST /de2api/chartData/getData with the valid sceneId but substitutes the tableId and field IDs of a sensitive internal dataset such as HR or financial data. …
Remediation Vendor-released patch: upgrade DataEase to version 2.10.24 or later, which adds validation that the tableId and field IDs in the getData request belong to the shared resource (fix commit c4e85a981e53c95b1ea73757db31e3025efdc410, release https://github.com/dataease/dataease/releases/tag/v2.10.24, advisory https://github.com/dataease/dataease/security/advisories/GHSA-qcf4-345v-6vg9). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Audit all active DataEase share-link tokens and immediately revoke any shared with external or untrusted recipients; document current internal share-link users and their permitted datasets. …
