CVE-2020-3342


A vulnerability in the software update feature of Cisco Webex Meetings Desktop App for Mac could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system. The vulnerability is due to improper validation of cryptographic protections on files that are downloaded by the application as part of a software update. An attacker could exploit this vulnerability by persuading a user to go to a website that returns files to the client that are similar to files that are returned from a valid Webex website. The client may fail to properly validate the cryptographic protections of the provided files before executing them as part of an update. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the user.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.8, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from cisco organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2020, 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.
