Who should care
Users of DataEase versions prior to 2.10.23 should apply the patch to prevent potential path traversal and arbitrary file write attacks. Affected operators, platforms, vulnerability-management, and security teams should review the vulnerability and implement necessary mitigations. Monitoring, detection, and logs for exposed assets should be checked for extra review.
Technical summary
The vulnerability exists in the DataEase template save functionality, specifically in the TemplateManageService#save, StaticResourceServer#saveFilesToServe, and the /de2api/templateManage/save endpoint. An attacker can exploit this by providing controlled staticResource names and Base64 content, leading to path traversal and arbitrary file writes. The issue is fixed in version 2.10.23. Defenders should review compensating controls for exposed systems while remediation is scheduled and verified.
Defensive priority
High
Recommended defensive actions
- Apply the patch by upgrading to DataEase version 2.10.23 or later
- Review and validate user-controlled input to prevent path traversal attacks
- Implement additional security measures to restrict file writes to authorized locations
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
