CVE-2021-47925: CMDBuild 3.3.2 Multiple Stored Cross-Site Scripting

CMDBuild 3.3.2 contains multiple stored cross-site scripting vulnerabilities that allow authenticated attackers to inject arbitrary web script or HTML via crafted input in card creation and file upload endpoints. Attackers can inject XSS payloads through Employee card parameters or SVG file attachments in the classes endpoint, which execute when other users view the affected records or preview attachments.

Security readout for executives and security teams

Plain-English summary

CMDBuild 3.3.2 can store attacker-supplied script or HTML inside records or uploaded SVG attachments. Because CMDBuild supports operational asset and workflow data, this can expose users to session abuse or unauthorized actions when malicious content is viewed. The sources do not show active exploitation, but a public exploit reference exists.

Executive priority

Treat this as a moderate-priority application security issue. It is not listed as actively exploited, but it affects authenticated enterprise workflows and has public exploit information. Prioritize internet-facing or broadly accessible CMDBuild instances first.

Technical view

This is multiple stored cross-site scripting in CMDBuild 3.3.2, mapped to CWE-79. Authenticated attackers can inject web script or HTML through Employee card parameters or SVG attachments in the classes endpoint. The content is stored and later executes for users viewing affected records or previews. CVSS v3.1 is 6.4, with low privileges required and changed scope.

Likely exposure

Exposure is most likely where CMDBuild 3.3.2 is deployed and accessible to internal users, contractors, or customers with authenticated accounts. Public internet exposure increases business risk, but the source bundle only names CMDBuild 3.3.2 as affected and provides no CPEs or broader version range.

Exploitation context

The bundle includes an ExploitDB reference, so public exploit information exists. KEV is false, and no cited source in the bundle states active exploitation. Abuse requires authentication, but stored XSS can affect other users after malicious records or attachments are viewed.

Researcher notes

Evidence is limited to CMDBuild 3.3.2, stored XSS vectors in card creation and SVG attachment handling, CVSS 6.4, and public advisory/exploit references. The bundle does not name a fixed version, patch, CPE, or active exploitation. Avoid expanding affected versions without vendor confirmation.

Mitigation direction

  • Identify and prioritize any CMDBuild 3.3.2 instances.
  • Check CMDBuild vendor guidance and latest-version information for upgrade direction.
  • Restrict CMDBuild access to trusted authenticated users while assessing exposure.
  • Limit or disable SVG attachment handling if operationally feasible.
  • Review stored records and attachments for unexpected script or HTML content.

Validation and detection

  • Confirm deployed CMDBuild versions through asset inventory or application administration.
  • Check whether Employee card fields are writable by low-privileged authenticated users.
  • Check whether class attachment previews allow SVG content in affected workflows.
  • Review CMDBuild audit logs for suspicious record changes or file uploads.
  • Verify upgraded or hardened instances render stored input as inert content.
