Amnesia:33 is a group of 33 vulnerabilities in open-source TCP/IP stack libraries. The vulnerabilities may be present in a wide range of operational technology, IoT, and connected device implementations.
Recent assessments:
ccondon-r7 at December 08, 2020 9:05pm UTC reported:
Sorta relying here on the fact that memory corruption vulns are difficult to weaponize or even trigger reliably, and it sounds like there will be lots of different implementations of the vulnerable libraries, so uniform attack surface area is going to be scarce. Rapid7βs IoT research lead noted as well that TCP stack issues like this may well require the attacker to be on same subnet, and itβs unlikely that upstream routers would accept unexpected/malformed packets. Thereβll be lots of fragmented vendor advisories trickling out in bits, Iβd expect. There may be more detail out on which to base assessments later this week.
