In Google Webmaster tools, I can see several duplicates of the article pages on our site. I can see this by viewing pages in the duplicate title tags section of Webmaster Tools. Here is an example of what I am seeing: Article: "Honeywell gets new six-year contract for satellite flight operations | NJBIZ" URLs of duplicate pages: /article/20130219/NJBIZ01/130219787&source=RSS /article/20130219/NJBIZ01/130219787/2995/Honeywell-gets-new-six-year-contract-for-satellite-flight-operations /article/20130219/NJBIZ01/130219787/1017/Honeywell-gets-new-six-year-contract-for-satellite-flight-operations /article/20130219/NJBIZ01/130219787/grapevine/Honeywell-gets-new-six-year-contract-for-satellite-flight-operations. Would these duplicate versions of pages hurt SEO overall, or is this common in a Content Management Systems?
NO.Google are very smart. Pages you are seen can be results of blackhat SEO.When Google will caught it he will penalized his website for being spammer.
