Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
When editing objects in the Syncope Console, incomplete HTML tags could be used to bypass HTML sanitization. This made it possible to inject stored XSS payloads which would trigger for other users during ordinary usage of the application. XSS payloads could also be injected in Syncope Enduser when editing “Personal Information” or “User Requests”: such payloads would trigger for administrators in Syncope Console, thus enabling session hijacking. Users are recommended to upgrade to version 3.0.9, which fixes this issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Stored XSS vulnerability in Apache Syncope where incomplete HTML tags bypass HTML sanitization. Attackers can inject malicious payloads through Console object editing or Enduser's Personal Information/User Requests features. These payloads execute when viewed by other users including administrators, enabling session hijacking.

MitigationUpgrade to version 3.0.9 which includes the fix for the incomplete HTML tag bypass in HTML sanitization.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Apache Syncope installed version
    Locate and read the Syncope version file or check the version via the administrative console or API endpoint that reports the product version
    Affected if The installed version is 2.1.0 through 3.0.8 inclusive (versions >= 2.1.0 and < 3.0.9)
  2. Determine if Console component is enabled
    Check the Console configuration or deployment settings to verify whether the administrative Console component is active
    Affected if Console is enabled and allows object editing functionality
  3. Determine if Enduser component is enabled
    Check the Enduser configuration or deployment settings to verify whether the self-service Enduser component is active
    Affected if Enduser is enabled and allows Personal Information or User Requests features
  4. Inspect stored data for incomplete HTML tags
    Examine stored content in the database or application for patterns like incomplete tags such as <script, <img, <iframe without closing brackets, or tags with attributes but no closing angle bracket
    Affected if Incomplete HTML tags are present in stored user-editable content that bypass sanitization
  5. Review recent audit logs for suspicious payload patterns
    Search application or audit logs for entries containing incomplete HTML fragments or known XSS probe patterns in user-submitted fields
    Affected if Logs show submission of incomplete HTML tags that were accepted by the system

You are affected if Apache Syncope version is between 2.1.0 and 3.0.8 and either Console object editing or Enduser features are enabled, with incomplete HTML tags successfully stored in the system.

Upgrade available Upgrade to 3.0.9 or later
Fixed in 3.0.9
Interim mitigation

Upgrade to version 3.0.9 which includes the fix for the incomplete HTML tag bypass in HTML sanitization.

Recommended fix High confidence

3.0.9

  1. 1. Back up your current Syncope installation, configuration files, and database before proceeding with the upgrade.
  2. 2. Download Apache Syncope version 3.0.9 from the official Apache Syncope distribution (downloads.apache.org/syncope) or build from source from the official repository.
  3. 3. Review the official Apache Syncope upgrade guide for migrating from version 2.x to 3.0.x, paying attention to any configuration changes or migration scripts required.
  4. 4. Stop the currently running Syncope services (both Console and Enduser components).
  5. 5. Update the Syncope binaries and deploy the new version 3.0.9 to your application server.
  6. 6. Run any required database migration scripts as documented in the upgrade guide.
  7. 7. Start the Syncope services and verify the application initializes correctly.
  8. 8. Test that HTML sanitization is working properly by attempting to save incomplete HTML tags in the Syncope Console and Enduser 'Personal Information' sections to confirm the XSS vulnerability is mitigated.
Caveat Upgrading from Syncope 2.x to 3.0.x may include breaking changes; review the migration guide for configuration and API adjustments
