A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). On SRX Series If Unified Threat Management (UTM) Enhanced Content Filtering (CF) is enabled and specific transit traffic is processed the PFE will crash and restart. This issue affects Juniper Networks Junos OS: 21.4 versions prior to 21.4R1-S2, 21.4R2 on SRX Series; 22.1 versions prior to 22.1R1-S1, 22.1R2 on SRX Series. This issue does not affect Juniper Networks Junos OS versions prior to 21.4R1.
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 and availability (service disruption) for affected systems. Impacting 29 products from juniper, from juniper, from juniper and 26 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2022, 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.
