A limitless resource allocation vulnerability in FPC resources of Juniper Networks Junos OS Evolved on PTX Series allows an unprivileged attacker to cause Denial of Service (DoS). Continuously polling the SNMP jnxCosQstatTable causes the FPC to run out of GUID space, causing a Denial of Service to the FPC resources. When the FPC runs out of the GUID space, you will see the following syslog messages. The evo-aftmand-bt process is asserting. fpc1 evo-aftmand-bt[17556]: %USER-3: get_next_guid: Ran out of Guid Space start 1748051689472 end 1752346656767 fpc1 audit[17556]: %AUTH-5: ANOM_ABEND auid=4294967295 uid=0 gid=0 ses=4294967295 pid=17556 comm="EvoAftManBt-mai" exe="/usr/sbin/evo-aftmand-bt" sig=6 fpc1 kernel: %KERN-5: audit: type=1701 audit(1648567505.119:57): auid=4294967295 uid=0 gid=0 ses=4294967295 pid=17556 comm="EvoAftManBt-mai" exe="/usr/sbin/evo-aftmand-bt" sig=6 fpc1 emfd-fpa[14438]: %USER-5: Alarm set: APP color=red, class=CHASSIS, reason=Application evo-aftmand-bt fail on node Fpc1 fpc1 emfd-fpa[14438]: %USER-3-EMF_FPA_ALARM_REP: RaiseAlarm: Alarm(Location: /Chassis[0]/Fpc[1] Module: sysman Object: evo-aftmand-bt:0 Error: 2) reported fpc1 sysepochman[12738]: %USER-5-SYSTEM_REBOOT_EVENT: Reboot [node] [ungraceful reboot] [evo-aftmand-bt exited] The FPC resources can be monitored using the following commands: user@router> start shell [vrf:none] user@router-re0:~$ cli -c "show platform application-info allocations app evo-aftmand-bt" | grep ^fpc | grep -v Route | grep -i -v Nexthop | awk '{total[$1] += $5} END { for (key in total) { print key " " total[key]/4294967296 }}' Once the FPCs become unreachable they must be manually restarted as they do not self-recover. This issue affects Juniper Networks Junos OS Evolved on PTX Series: All versions prior to 20.4R3-S4-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO version 21.2R1-EVO and later versions; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R2-EVO; 22.1-EVO versions prior to 22.1R2-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 18 products from juniper, from juniper, from juniper and 15 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.
