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
An improper initialization vulnerability was found in Galleon. When using Galleon to provision custom EAP or EAP-XP servers, the servers are created unsecured. This issue could allow an attacker to access remote HTTP services available from the server.

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 · moderate confidence

Galleon, a provisioning tool for JBoss EAP and EAP-XP servers, creates custom server instances without proper security initialization when provisioning. This results in unsecured servers with potentially exposed HTTP services that could be accessed remotely without authentication.

MitigationReview Galleon provisioning configurations to ensure security settings are explicitly applied during server creation, or implement post-provisioning security hardening steps for any EAP/EAP-XP servers provisioned with custom profiles.

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 Galleon-provisioned EAP instances
    Look for Galleon configuration files (usually named provisioning.xml or galleon.xml) in the server installation directory or check the server startup logs for Galleon provisioning messages.
    Affected if Galleon was used to create the server instance and no post-provisioning security hardening was applied.
  2. Verify security realm configuration
    Inspect the standalone.xml (or domain.xml) configuration file in the EAP instance configuration directory. Locate the <security-realm> sections and verify that authentication is properly configured for both management and application interfaces.
    Affected if Security realms are missing, disabled, or set to allow anonymous/bypass authentication.
  3. Check HTTP interface accessibility
    Attempt to access the management HTTP interface (typically port 9990) and application HTTP endpoints from an unauthorized host. Verify that authentication is required.
    Affected if HTTP management interface or application services respond without requiring authentication.
  4. Review management interface security settings
    In the standalone.xml, examine the <management> section. Check that <http-interface> has security-enabled="true" set and that <security-realm> references a properly configured security realm.
    Affected if Management HTTP interface has security disabled or no security realm is assigned.

You are affected if Galleon was used to provision JBoss EAP or EAP-XP servers and the resulting server instances have unsecured HTTP interfaces or missing security realm configurations that allow unauthenticated remote access.
