Unauthenticated information disclosure through inadequate core error checking

Information disclosure in Joomla! CMS 1.7.1 and earlier allows remote attackers to read sensitive data through core error handling. The vendor states only that inadequate error checking in the core exposes information and has not identified the affected function, request, error path, or disclosed data. No authentication or user interaction is required, but the public record does not establish which request triggers disclosure or whether default installations expose it.
