CVSS: 8.2EPSS: 0%CPEs: 6EXPL: 0CVE-2024-47494 – Junos OS: Due to a race condition AgentD process causes a memory corruption and FPC reset
https://notcve.org/view.php?id=CVE-2024-47494
A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in the AgentD process of Juniper Networks Junos OS allows an attacker who is already causing impact to established sessions which generates counter changes picked up by the AgentD process during telemetry polling, to move the AgentD process into a state where AgentD attempts to reap an already destroyed sensor. This reaping attempt then leads to memory corruption causing the FPC to crash which is a Denial of Service (DoS). The FPC will recover automatically without user intervention after the crash. This issue affects Junos OS: * All versions before 21.4R3-S9 * From 22.2 before 22.2R3-S5, * From 22.3 before 22.3R3-S4, * From 22.4 before 22.4R3-S3, * From 23.2 before 23.2R2-S2, * From 23.4 before 23.4R2. This issue does not affect Junos OS Evolved. • https://supportportal.juniper.net/JSA88121 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-47493 – Junos OS: MX Series: Trio-based FPCs: Continuous physical Interface flaps causes local FPC to crash
https://notcve.org/view.php?id=CVE-2024-47493
A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of the Juniper Networks Junos OS on the SRX5K, SRX4600 and MX Series platforms with Trio-based FPCs allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). In case of channelized Modular Interface Cards (MICs), every physical interface flap operation will leak heap memory. Over a period of time, continuous physical interface flap operations causes local FPC to eventually run out of memory and crash. Below CLI command can be used to check the memory usage over a period of time: user@host> show chassis fpc Temp CPU Utilization (%) CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt 1min 5min 15min DRAM (MB) Heap Buffer 0 Online 43 41 2 2048 49 14 1 Online 43 41 2 2048 49 14 2 Online 43 41 2 2048 49 14 This issue affects Junos OS on SRX5K, SRX4600 and MX Series: * All versions before 21.2R3-S7, * from 21.4 before 21.4R3-S6, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2, * from 23.4 before 23.4R2.

CVSS: 8.7EPSS: 0%CPEs: 12EXPL: 0CVE-2024-47491 – Junos OS and Junos OS Evolved: Receipt of a specific malformed BGP path attribute leads to an RPD crash
https://notcve.org/view.php?id=CVE-2024-47491
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. 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.

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.

https://notcve.org/view.php?id=CVE-2024-47490
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. • https://supportportal.juniper.net/JSA83009 • CWE-923: Improper Restriction of Communication Channel to Intended Endpoints •
CVSS: 6.9EPSS: 0%CPEs: 8EXPL: 0CVE-2024-47489 – Junos OS Evolved: ACX Series: Receipt of specific transit protocol packets is incorrectly processed by the RE
https://notcve.org/view.php?id=CVE-2024-47489
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. • https://supportportal.juniper.net • CWE-755: Improper Handling of Exceptional Conditions •
