An improper input validation weakness in the device control daemon process (dcd) of Juniper Networks Junos OS allows an attacker to cause a Denial of Service to the dcd process and interfaces and connected clients when the Junos device is requesting an IP address for itself. Junos devices are not vulnerable to this issue when not configured to use DHCP. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D40 on SRX Series; 12.3X48 versions prior to 12.3X48-D20 on SRX Series; 14.1X53 versions prior to 14.1X53-D40 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100; 15.1X49 versions prior to 15.1X49-D20 on SRX Series; 15.1X53 versions prior to 15.1X53-D68 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D235 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D495 on NFX150, NFX250; 15.1X53 versions prior to 15.1X53-D590 on EX2300/EX3400; 15.1 versions prior to 15.1R7-S2.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.3, 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 limited integrity, for affected systems. Impacting 15 products from juniper, from juniper, from juniper and 12 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

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.
