CVE-2018-0209


A vulnerability in the Simple Network Management Protocol (SNMP) subsystem communication channel through the Cisco 550X Series Stackable Managed Switches could allow an authenticated, remote attacker to cause the device to reload unexpectedly, causing a denial of service (DoS) condition. The device nay need to be manually reloaded to recover. The vulnerability is due to lack of proper input throttling of ingress SNMP traffic over an internal interface. An attacker could exploit this vulnerability by sending a crafted, heavy stream of SNMP traffic to the targeted device. An exploit could allow the attacker to cause the device to reload unexpectedly, causing a DoS condition. Cisco Bug IDs: CSCvg22135.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.7, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 20 products from cisco, from cisco, from cisco and 17 others, organizations running these solutions should prioritize assessment and patching.

Historical Context

First disclosed in 2018, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques.

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.
