Hi.
Well, both blind injection and dns exfiltration require usage of comma
character - because there is a need for extracting bits/characters/chunks
(SUBSTRC).
Nonetheless, that method you referenced would require a noticable work to
be done on a Oracle side. I would suggest you to try to use a manual dns
exfiltration approach without SUBSTRC (whole query response into the dns
request - and pray that it fits within the size limits)
Kind regards,
Miroslav Stampar
