"The remote OT asset is affected by a vulnerability.");

"A vulnerability in Internet Key Exchange version 1 (IKEv1) packet processing 
code in Cisco IOS, Cisco IOS XE, and Cisco IOS XR Software could allow an unauthenticated, 
remote attacker to retrieve memory contents, which could lead to the disclosure 
of confidential information. 
The vulnerability is due to insufficient condition checks in the part of 
the code that handles IKEv1 security negotiation requests. An attacker could 
exploit this vulnerability by sending a crafted IKEv1 packet to an affected 
device configured to accept IKEv1 security negotiation requests. 
A successful exploit could allow the attacker to retrieve memory contents, 
which could lead to the disclosure of confidential information.
