Executive Summary

This vulnerability is a stored cross-site scripting (XSS) flaw in DataEase, an open-source BI tool. It exists in the symbolic map component where malicious input in the tooltip background color field can execute arbitrary scripts when rendered. The attack requires manage permissions to inject the payload but only read access to trigger it.

Detection Guidance

To detect this vulnerability, inspect DataEase installations for versions 2.10.25, 2.10.26, or dev-v2 commit 0ae4a3d. Check for malicious POST requests to /dataVisualization/updateCanvas modifying customAttr.tooltip.backgroundColor. Review symbolic-map.ts for style.innerHTML usage in tooltip rendering.

Impact Analysis

An attacker could steal session cookies, perform actions on your behalf, or redirect you to malicious sites. Users with read access to dashboards could unknowingly trigger the XSS when viewing symbolic map charts with injected payloads.

Compliance Impact

This XSS vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality principles. For HIPAA, it may compromise protected health information integrity if exploited in healthcare dashboards.

Mitigation Strategies

Immediately upgrade to a patched version beyond 2.10.26. If unavailable, restrict manage permissions to trusted users only. Disable dashboard editing for untrusted users. Implement input validation for customAttr.tooltip.backgroundColor to reject non-color values. Replace style.innerHTML with DOM/CSS APIs for tooltip rendering.
