If the BMC has write access to host memory it could surely use that access to create a side channel using the host's network interfaces.
Having said that, it would be nice if networks were segmented in the way you describe. I've been appalled at the lack of segmentation I've seen in companies of all sizes that I've had gigs for.
- bayindirh 8y agoToday's network cards are small computers of their own. So it'd be very hard to inject packages with all this kernel-hardware integration at the module level IMHO. The card would probably throw a tantrum if you try to access it directly. TBH, while I'm knowledgeable about hardware, I'm a total beginner in attack side of cybersecurity. At least, we are segmenting our networks like that.
