CVE-2022-20714


A vulnerability in the data plane microcode of Lightspeed-Plus line cards for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause the line card to reset. This vulnerability is due to the incorrect handling of malformed packets that are received on the Lightspeed-Plus line cards. An attacker could exploit this vulnerability by sending a crafted IPv4 or IPv6 packet through an affected device. A successful exploit could allow the attacker to cause the Lightspeed-Plus line card to reset, resulting in a denial of service (DoS) condition for any traffic that traverses that line card.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.6, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 3 products from cisco, from cisco, from cisco organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2022, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For cisco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
