What qualifies a paper/dissertation to received the status 'published'
The exact meaning of the word "publication" is dependent on context.  In some contexts, it might be understood to include only articles accepted in peer-reviewed journals or conference proceedings.  (Impact factor is not usually a consideration here.)  In other contexts, it might also include books, dissertations, lecture notes, arXiv preprints, and other documents that have been made publicly available.

So whether a dissertation should be "named as a published paper" depends on your audience.

For academic CVs, people often create two sections: one that lists peer-reviewed publications, and another that lists non-peer-reviewed writings.  This removes any ambiguity.  A master's dissertation would go in the non-peer-reviewed section.

If you are writing a resume for the business world, standards might be different.  http://workplace.stackexchange.com might be a better place to ask about that situation.
