Zoom clients prior to 5.13.5 contain an improper trust boundary implementation vulnerability. If a victim saves a local recording to an SMB location and later opens it using a link from Zoom’s web portal, an attacker positioned on an adjacent network to the victim client could set up a malicious SMB server to respond to client requests, causing the client to execute attacker controlled executables. This could result in an attacker gaining access to a user's device and data, and remote code execution.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.3, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 4 products from zoom, from zoom, from zoom and 1 other, organizations running these solutions should prioritize assessment and patching.
Reported in 2023, 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.

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 zoom'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.
