PHOENIX CONTACT TC ROUTER 3002T-4G through 2.05.3, TC ROUTER 2002T-3G through 2.05.3, TC ROUTER 3002T-4G VZW through 2.05.3, TC ROUTER 3002T-4G ATT through 2.05.3, TC CLOUD CLIENT 1002-4G through 2.03.17, and TC CLOUD CLIENT 1002-TXTX through 1.03.17 devices contain a hardcoded certificate (and key) that is used by default for web-based services on the device. Impersonation, man-in-the-middle, or passive decryption attacks are possible if the generic certificate is not replaced by a device-specific certificate during installation.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.5, 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 confidentiality (data exposure), for affected systems. Impacting 12 products from phoenixcontact, from phoenixcontact, from phoenixcontact and 9 others, 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 phoenixcontact'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.
