CVE-2024-47489 1 Juniper 1 Junos Evolved 2024-11-21 5.8 Medium
An Improper Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of the Juniper Networks Junos OS Evolved on ACX Series devices allows an unauthenticated, network based attacker sending specific transit protocol traffic to cause a partial Denial of Service (DoS) to downstream devices. Receipt of specific transit protocol packets is incorrectly processed by the Routing Engine (RE), filling up the DDoS protection queue which is shared between routing protocols. This influx of transit protocol packets causes DDoS protection violations, resulting in protocol flaps which can affect connectivity to networking devices. This issue affects both IPv4 and IPv6. This issue does not require any specific routing protocol to be configured or enabled. The following commands can be used to monitor the DDoS protection queue:        labuser@re0> show evo-pfemand host pkt-stats     labuser@re0> show host-path ddos all-policers This issue affects Junos OS Evolved:  * All versions before 21.4R3-S8-EVO,  * from 22.2 before 22.2R3-S4-EVO,  * from 22.3 before 22.3R3-S4-EVO,  * from 22.4 before 22.4R3-S3-EVO,  * from 23.2 before 23.2R2-EVO,  * from 23.4 before 23.4R1-S1-EVO, 23.4R2-EVO,  * from 24.2 before 24.2R2-EVO.
CVE-2024-39512 1 Juniper 1 Junos Evolved 2024-11-21 6.6 Medium
An Improper Physical Access Control vulnerability in the console port control of Juniper Networks Junos OS Evolved allows an attacker with physical access to the device to get access to a user account. When the console cable is disconnected, the logged in user is not logged out. This allows a malicious attacker with physical access to the console to resume a previous session and possibly gain administrative privileges. This issue affects Junos OS Evolved: * from 23.2R2-EVO before 23.2R2-S1-EVO,  * from 23.4R1-EVO before 23.4R2-EVO.
CVE-2024-47491 1 Juniper 2 Junos, Junos Evolved 2024-10-22 5.9 Medium
An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause Denial of Service (DoS). When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts. Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices. While this issue affects systems running 32-bit and 64-bit systems, the probability of impact on 64-bit system is extremely low.  According to KB25803 https://supportportal.juniper.net/s/article/Junos-How-to-check-if-Junos-OS-is-64-or-32-bit-on-a-router , customers can confirm 32-bit or 64-bit system via the ' show version detail ' command:      lab@router> show version detail| match 32      JUNOS 32-bit kernel Software Suite       lab@router> show version detail| match 64      JUNOS 64-bit kernel Software Suite  This issue affects:  Juniper Networks Junos OS:  * All versions before 21.4R3-S8,  * from 22.2 before 22.2R3-S4,  * from 22.4 before 22.4R3-S3,  * from 23.2 before 23.2R2-S1,  * from 23.4 before 23.4R1-S2, 23.4R2.  Juniper Networks Junos OS Evolved:  * All versions before 21.4R3-S8-EVO, * from 22.2 before 22.2R3-S4-EVO, * from 22.4 before 22.4R3-S3-EVO, * from 23.2 before 23.2R2-S1-EVO, * from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO.
CVE-2024-39547 1 Juniper 2 Junos, Junos Evolved 2024-10-15 7.5 High
An Improper Handling of Exceptional Conditions vulnerability in the rpd-server of Juniper Networks Junos OS and Junos OS Evolved within cRPD allows an unauthenticated network-based attacker sending crafted TCP traffic to the routing engine (RE) to cause a CPU-based Denial of Service (DoS). If specially crafted TCP traffic is received by the control plane, or a TCP session terminates unexpectedly, it will cause increased control plane CPU utilization by the rpd-server process. While not explicitly required, the impact is more severe when RIB sharding is enabled.

CVE-2024-47490 1 Juniper 1 Junos Evolved 2024-10-15 8.2 High
An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows an unauthenticated, network based attacker to cause increased consumption of resources, ultimately resulting in a Denial of Service (DoS). When specific transit MPLS packets are received by the PFE, these packets are internally forwarded to the Routing Engine (RE), rather than being handled appropriately. Continuous receipt of these MPLS packets causes resources to be exhausted. MPLS config is not required to be affected by this issue.  This issue affects Junos OS Evolved ACX 7000 Series:  * All versions before 21.4R3-S9-EVO, * 22.2-EVO before 22.2R3-S4-EVO,  * 22.3-EVO before 22.3R3-S3-EVO,  * 22.4-EVO before 22.4R3-S2-EVO,  * 23.2-EVO before 23.2R2-EVO,  * 23.4-EVO before 23.4R1-S1-EVO, 23.4R2-EVO.
CVE-2024-47499 1 Juniper 2 Junos, Junos Evolved 2024-10-15 7.5 High
An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS).  In a scenario where BGP Monitoring Protocol (BMP) is configured with rib-in pre-policy monitoring, receiving a BGP update with a specifically malformed AS PATH attribute over an established BGP session, can cause an RPD crash and restart. This issue affects: Junos OS:  * All versions before 21.2R3-S8, * 21.4 versions before 21.4R3-S8, * 22.2 versions before 22.2R3-S4, * 22.3 versions before 22.3R3-S3, * 22.4 versions before 22.4R3-S2, * 23.2 versions before 23.2R2-S1, * 23.4 versions before 23.4R1-S2, 23.4R2; Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.4 versions before 21.4R3-S8-EVO, * 22.2 versions before 22.2R3-S4-EVO, * 22.3 versions before 22.3R3-S3-EVO, * 22.4 versions before 22.4R3-S2-EVO, * 23.2 versions before 23.2R2-S1-EVO, * 23.4 versions before 23.4R1-S2-EVO, 23.4R2-EVO.
CVE-2024-47502 1 Juniper 1 Junos Evolved 2024-10-15 7.5 High
An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS). In specific cases the state of TCP sessions that are terminated is not cleared, which over time leads to an exhaustion of resources, preventing new connections to the control plane from being established. A continuously increasing number of connections shown by: user@host > show system connections is indicative of the problem. To recover the respective RE needs to be restarted manually. This issue only affects IPv4 but does not affect IPv6. This issue only affects TCP sessions established in-band (over an interface on an FPC) but not out-of-band (over the management ethernet port on the routing-engine). This issue affects Junos OS Evolved:  * All versions before 21.4R3-S9-EVO, * 22.2 versions before 22.2R3-S4-EVO, * 22.4 version before 22.4R3-S3-EVO, * 23.2 versions before 23.2R2-S1-EVO, * 23.4 versions before 23.4R2-EVO.
CVE-2024-47495 1 Juniper 1 Junos Evolved 2024-10-15 6.7 Medium
An Authorization Bypass Through User-Controlled Key vulnerability allows a locally authenticated attacker with shell access to gain full control of the device when Dual Routing Engines (REs) are in use on Juniper Networks Junos OS Evolved devices. This issue affects: Juniper Networks Junos OS Evolved with dual-REs: * All versions before 21.2R3-S8-EVO, * from 21.4-EVO before 21.4R3-S8-EVO, * from 22.2-EVO before 22.2R3-S4-EVO, * from 22.3-EVO before 22.3R3-S4-EVO, * from 22.4-EVO before 22.4R3-S3-EVO, * from 23.2-EVO before 23.2R2-S1-EVO, * from 23.4-EVO before 23.4R2-S1-EVO. This issue does not affect Juniper Networks Junos OS.
CVE-2024-47507 1 Juniper 2 Junos, Junos Evolved 2024-10-15 5.8 Medium
An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause an integrity impact to the downstream devices. When a peer sends a BGP update message which contains the aggregator attribute with an ASN value of zero (0), rpd accepts and propagates this attribute, which can cause issues for downstream BGP peers receiving this. This issue affects: Junos OS: * All versions before 21.4R3-S6, * 22.2 versions before 22.2R3-S3, * 22.4 versions before 22.4R3;  Junos OS Evolved:  * All versions before 21.4R3-S7-EVO, * 22.2 versions before 22.2R3-S4-EVO, * 22.4 versions before 22.4R3-EVO.
