Rewterz Threat Advisory – CVE-2020-10136 – Cisco NX-OS Software Unexpected IP in IP Packet Processing Vulnerability

June 2, 2020

Severity

Medium

Analysis Summary

The vulnerability is due to the affected device unexpectedly decapsulating and processing IP in IP packets that are destined to a locally configured IP address. An attacker could exploit this vulnerability by sending a crafted IP in IP packet to an affected device. A successful exploit could cause the affected device to unexpectedly decapsulate the IP in IP packet and forward the inner IP packet. This may result in IP packets bypassing input access control lists (ACLs) configured on the affected device or other security boundaries defined elsewhere in the network.

Impact

  • Security bypass
  • Denial of service

Remediation

Refer to vendor’s advisory for the list of complete list of affected products and upgraded patches.
