Does any Theravada Suttas / sources refer to Oozing orifices? What are the Suttas? According to Satipatthana Mula (By Sujato Bhikkhu edited by Piya Tan) Śāripūtrābhidharma Satipatthana contains a section on oozing orifices. What exactly does Śāripūtrābhidharma sources say about oozing orifices in English? Are there are parallels in Theravada literature especially the Tripitaka which compair with what Śāripūtrābhidharma sources say?
The Theravada satipatthana sutta contains the same reference:


  “Again, bhikkhus, as though he were to see a corpse thrown aside in a charnel ground, one, two, or three days dead, bloated, livid, and oozing matter, a bhikkhu compares this same body with it thus: ‘This body too is of the same nature, it will be like that, it is not exempt from that fate.’


(MN 10 - Bodhi, Trans)

The Visuddhimagga explains the phrase (festering = oozing):


  The festering: what is trickling with pus in broken places is festering (vipubba).
  What is festering is the same as “the festering” (vipubbaka). Or alternatively,
  what is festering (vipubba) is vile (kucchita) because of repulsiveness, thus it is
  “the festering” (vipubbaka). This is a term for a corpse in that particular state.
