CVE-2020-1688

On Juniper Networks SRX Series and NFX Series, a local authenticated user with access to the shell may obtain the Web API service private key that is used to provide encrypted communication between the Juniper device and the authenticator services. Exploitation of this vulnerability may allow an attacker to decrypt the communications between the Juniper device and the authenticator service. This Web API service is used for authentication services such as the Juniper Identity Management Service, used to obtain user identity for Integrated User Firewall feature, or the integrated ClearPass authentication and enforcement feature. This issue affects Juniper Networks Junos OS on Networks SRX Series and NFX Series: 12.3X48 versions prior to 12.3X48-D105; 15.1X49 versions prior to 15.1X49-D190; 16.1 versions prior to 16.1R7-S8; 17.2 versions prior to 17.2R3-S4; 17.3 versions prior to 17.3R3-S8; 17.4 versions prior to 17.4R2-S11, 17.4R3; 18.1 versions prior to 18.1R3-S7; 18.2 versions prior to 18.2R3; 18.3 versions prior to 18.3R2-S4, 18.3R3; 18.4 versions prior to 18.4R1-S7, 18.4R2; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S4, 19.2R2.

Security Impact Summary

This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.5, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 17 products from juniper, from juniper, from juniper and 14 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 juniper'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.
