Who should care

Users of DataEase versions prior to 2.10.23 should apply the patch to prevent potential unauthorized access. Affected operators include DataEase administrators and users. Platforms include those hosting DataEase. Vulnerability-management and security teams should review and update token handling and verification processes.

Technical summary

The vulnerability exists in the TokenFilter#doFilter() method, where X-DE-TOKEN values are passed to TokenUtils.validate(). This method checks only for token presence and length before userBOByToken(token) uses JWT.decode() without signature verification. This allows forged tokens with chosen uid and oid values to be accepted when licenseValid=true. The issue is fixed in version 2.10.23. Affected product context includes DataEase versions prior to 2.10.23. Defensive impact includes potential unauthorized access.

Defensive priority

High

Recommended defensive actions

  • Apply the patch by upgrading to DataEase version 2.10.23 or later
  • Review and update token handling and verification processes
  • Monitor for suspicious token usage and implement additional security measures
  • 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
