"The regulations are clear, so there could well be further technical directives that are designed to try and further clarify those regulations,'' Horner told motoring website Autosport.com.
Although it appears Red Bull won't face any punishment over the issue, a clarification or alteration of the rules could force some hurried technical changes.
And with the Hungarian Grand Prix being held this Sunday, Webber will be hoping the issue doesn't distract his team from solving the speed issues which dogged him in Germany.
Having to start from eighth on the grid after a five-spot penalty for replacing a gearbox before qualifying, Webber never threatened to challenge during the race.
He said he was at a loss to explain why his RB8 was so slow.
"I just couldn't do the lap times,'' Webber said.
"We thought about doing something different strategy-wise, but if you don't have the pace you can't even do that.
"What happened this afternoon is bizarre because we've been so competitive in the last few races and here I finished 40 seconds behind the winner.''
Despite the disappointing weekend in Germany, Webber was staying positive going into Hungary.
Webber won at the Hungaroring in 2010 and appeared to be happy to be heading to eastern Europe.
"We'll look long and hard into what happened at Hockenheim to ensure we're back to our usual levels of competitiveness,'' he said.
"What Germany proved above all else is how important it is to start at the front. If you're back in the pack, you get caught up in slower cars and that results in you dropping even further back.
"I'm confident that we can be strong again.''
