An Uncontrolled Resource Consumption vulnerability in the aftmand process of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to consume memory resources, resulting in a Denial of Service (DoS) condition. The processes do not recover on their own and must be manually restarted. This issue affects both IPv4 and IPv6. Changes in memory usage can be monitored using the following CLI command: user@device> show system memory node <fpc slot> | grep evo-aftmann This issue affects Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.3 versions before 21.3R3-S5-EVO, * 21.4 versions before 21.4R3-S5-EVO, * 22.1 versions before 22.1R3-S4-EVO, * 22.2 versions before 22.2R3-S4-EVO, * 22.3 versions before 22.3R3-S3-EVO, * 22.4 versions before 22.4R2-S2-EVO, 22.4R3-EVO, * 23.2 versions before 23.2R1-S1-EVO, 23.2R2-EVO.
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 1 product from juniper organizations running these solutions should prioritize assessment and patching.
Reported in 2024, 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.
