ColdFusion 9 solr service exposed

Description

Adobe ColdFusion 9.0 contains a security vulnerability (CVE-2010-0185) that exposes the Solr search service to unauthorized external access. By default, the Solr service collections are accessible via direct URL requests from any remote machine without authentication. This allows unauthorized users to query, search, and potentially index sensitive data stored within ColdFusion Solr collections, which may include application data, user information, or other indexed content.

Remediation

Restrict external access to ColdFusion Solr collections by implementing network-level access controls. Configure your web server or firewall to block external requests to the Solr service endpoints (typically located at /solr/*). For Apache web servers, add the following configuration to deny external access:

<Location /solr>
  Order Deny,Allow
  Deny from all
  Allow from 127.0.0.1
  Allow from localhost
</Location>

For IIS servers, configure URL rewrite rules or IP restrictions to limit access to localhost only. Verify the configuration by attempting to access the Solr service from an external IP address to ensure access is properly denied. Refer to Adobe's official security bulletin for platform-specific implementation guidance.
