CVE-2011-3609
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 · uneditedA CSRF issue was found in JBoss Application Server 7 before 7.1.0. JBoss did not properly restrict access to the management console information (for example via the "Access-Control-Allow-Origin" HTTP access control flag). This can lead to unauthorized information leak if a user with admin privileges visits a specially-crafted web page provided by a remote attacker.
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 confidenceJBoss Application Server 7 before 7.1.0 improperly handled Cross-Origin requests to the management console, missing proper Access-Control-Allow-Origin header validation. A remote attacker could craft a malicious webpage that, when visited by an authenticated administrator, would cause the victim's browser to make unauthorized requests to the JBoss management API, leading to information disclosure.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify JBoss AS installation and versionCheck the installed version by reviewing the JBoss startup logs, or examine the jboss-as-modules.jar or jboss-as-server.jar manifest, or query the management API endpoint / (root) for version informationAffected if The installed version is 7.0.0, 7.0.1, or 7.0.2
-
Confirm management console is accessibleVerify that the JBoss management console or management API is reachable over HTTP/HTTPS on the configured management port (typically 9990 or 8080)Affected if The management interface is exposed and accessible to users or attackers
-
Check for CORS header validationSend an HTTP request to the management API endpoint with an arbitrary Origin header (e.g., Origin: http://malicious.com) and inspect the response headers for Access-Control-Allow-OriginAffected if The response reflects the arbitrary Origin back without validation, or allows wildcards ("*"), indicating missing CORS controls
A user is affected if they run JBoss Application Server versions 7.0.0, 7.0.1, or 7.0.2 with the management console accessible and without proper Access-Control-Allow-Origin validation on management endpoints.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade JBoss Application Server to version 7.1.0 or later, or implement proper CORS headers and CSRF tokens on management console endpoints to restrict cross-origin access.
