In short
A flaw in NI grpc-device's streaming API allows attackers to craft malicious messages that dereference untrusted memory pointers, potentially taking over the affected system remotely without needing special access.
Technical detail
CWE-822 untrusted pointer dereference in the sideband streaming API vector allows remote attackers to trigger arbitrary memory access via crafted Moniker protobuf messages; successful exploitation results in remote code execution. Affects NI grpc-device ≤2.17.0; no authentication or privilege escalation required.
Summary generated and translated by AI from the official description.
There is an untrusted pointer dereference vulnerability in the NI grpc-device sideband streaming API that may allow an attacker to cause an arbitrary memory dereference, potentially resulting in remote code execution. Successful exploitation requires an attacker to supply a specially crafted Moniker protobuf message. This affects NI grpc-device 2.17.0 and prior versions.
