A certain crafted HTTP packet can trigger an uninitialized function pointer deference vulnerability in the Packet Forwarding Engine manager (fxpc) on all EX, QFX and MX Series devices in a Virtual Chassis configuration. This issue can result in a crash of the fxpc daemon or may potentially lead to remote code execution. This issue only occurs when the crafted packet it destined to the device. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D47 on EX and QFX Virtual Chassis Platforms; 15.1 versions prior to 15.1R7-S3 all Virtual Chassis Platforms 15.1X53 versions prior to 15.1X53-D50 on EX and QFX Virtual Chassis Platforms.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.8, 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), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 31 products from juniper, from juniper, from juniper and 28 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2019, 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.
