On the QFX3500 and QFX3600 platforms, the number of bytes collected from the RANDOM_INTERRUPT entropy source when the device boots up is insufficient, possibly leading to weak or duplicate SSH keys or self-signed SSL/TLS certificates. Entropy increases after the system has been up and running for some time, but immediately after boot, the entropy is very low. This issue only affects the QFX3500 and QFX3600 switches. No other Juniper Networks products or platforms are affected by this weak entropy vulnerability.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.5, 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 confidentiality (data exposure), for affected systems. Impacting 3 products from juniper, from juniper, from juniper organizations running these solutions should prioritize assessment and patching.
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.

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.
