Intel is Manga first of all.
As for how they actually win, without intel White Rage is too dangerous for them. It goes off, paralyzes them and then Jiraiya gets picked off in a heartbeat. Nagato can protect himself due to Shinra Tensei and the fact that he can sense chakra. People will say nonsense like "Nagato deflects it" or "Nagato absorbs it" or "Nagato nukes it" even though he won't even know to deflect it when Kabuto doesn't even need to shoot it at him and when Nagato has zero idea what the jutsu does in the first place. We saw how two people w/ the capability to destroy the dragon reacted to it w/o knowledge.
Orochimaru on his own can pressure Jiraiya w/ Parasite Clones or Shadow clones, spores (released and travel through the air) and back attacks via Mayfly. Orochimaru can survive most of his jutsu w/ Oral Rebirth or use Mayfly to escape. Let alone w/ Kabuto's help as his techs pretty much target multiple people at the same time.
-CST is survived by him turning into liquid.
-CT might be a major issue, but a combination of his liquefication and Orochimaru's attack prevention technique should let him escape relatively unscathed. However the most likely scenario is that Kabuto kills Nagato long before this ever becomes a factor due to the fact he has zero intel on Kabuto's abilities.
Give Nagato intel on Kabuto's abilities and his team has a far greater chance of victory.
