CVE-2025-59967 1 Juniper 7 Acx7024, Acx7024x, Acx7100-32c and 4 more 2026-01-23 6.5 Medium
A NULL Pointer Dereference vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 devices allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). Whenever specific valid multicast traffic is received on any layer 3 interface the evo-pfemand process crashes and restarts. Continued receipt of specific valid multicast traffic results in a sustained Denial of Service (DoS) attack. This issue affects Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509:  * from 23.2R2-EVO before 23.2R2-S4-EVO,  * from 23.4R1-EVO before 23.4R2-EVO. This issue affects IPv4 and IPv6. This issue does not affect Junos OS Evolved ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 versions before 23.2R2-EVO.

This issue affects only Juniper Networks Junos OS Evolved ACX Series devices using the Paragon Active Assurance Test Agent software installed on these devices from 23.1R1-EVO through 23.2R2-EVO.  This issue does not affect releases before 23.1R1-EVO.
CVE-2024-39531 1 Juniper 7 Acx7020, Acx7024, Acx7024x and 4 more 2026-01-22 7.5 High
An Improper Handling of Values vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows a network-based, unauthenticated attacker to cause a Denial-of-Service (DoS). If a value is configured for DDoS bandwidth or burst parameters for any protocol in a queue, all protocols which share the same queue will have their bandwidth or burst value changed to the new value. If, for example, OSPF was configured with a certain bandwidth value, ISIS would also be limited to this value. So inadvertently either the control plane is open for a high level of specific traffic which was supposed to be limited to a lower value, or the limit for a certain protocol is so low that chances to succeed with a volumetric DoS attack are significantly increased.  This issue affects Junos OS Evolved on ACX 7000 Series: * All versions before 21.4R3-S7-EVO, * 22.1 versions before 22.1R3-S6-EVO,  * 22.2 versions before 22.2R3-S3-EVO, * 22.3 versions before 22.3R3-S3-EVO,  * 22.4 versions before 22.4R3-S2-EVO, * 23.2 versions before 23.2R2-EVO, * 23.4 versions before 23.4R1-S1-EVO, 23.4R2-EVO.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On receipt of specific IPv6 transit traffic, Junos OS Evolved on ACX7100-48L, ACX7100-32C and ACX7509 sends this traffic to the Routing Engine (RE) instead of forwarding it, leading to increased CPU utilization of the RE and a partial DoS. This issue only affects systems configured with IPv6. This issue does not affect ACX7024 which is supported from 22.3R1-EVO onwards where the fix has already been incorporated as indicated in the solution section. This issue affects Juniper Networks Junos OS Evolved on ACX7100-48L, ACX7100-32C, ACX7509: 21.1-EVO versions prior to 21.1R3-S2-EVO; 21.2-EVO versions prior to 21.2R3-S2-EVO; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R1-S1-EVO, 21.4R2-EVO.
