Description
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.
