CVSS: 8.7EPSS: 0%CPEs: 18EXPL: 0CVE-2024-39552 – Junos OS and Junos OS Evolved: Malformed BGP UPDATE causes RPD crash
https://notcve.org/view.php?id=CVE-2024-39552
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 the RPD process to crash leading to a Denial of Service (DoS). When a malformed BGP UPDATE packet is received over an established BGP session, RPD crashes and restarts. Continuous receipt of the malformed BGP UPDATE messages will create a sustained Denial of Service (DoS) condition for impacted devices. This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations. This issue requires a remote attacker to have at least one established BGP session. This issue affects: Juniper Networks Junos OS: * All versions earlier than 20.4R3-S9; * 21.2 versions earlier than 21.2R3-S7; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S6; * 22.1 versions earlier than 22.1R3-S4; * 22.2 versions earlier than 22.2R3-S3; * 22.3 versions earlier than 22.3R3-S2; * 22.4 versions earlier than 22.4R3; * 23.2 versions earlier than 23.2R2. Juniper Networks Junos OS Evolved: * All versions earlier than 21.2R3-S7; * 21.3-EVO versions earlier than 21.3R3-S5; * 21.4-EVO versions earlier than 21.4R3-S8; * 22.1-EVO versions earlier than 22.1R3-S4; * 22.2-EVO versions earlier than 22.2R3-S3; * 22.3-EVO versions earlier than 22.3R3-S2; * 22.4-EVO versions earlier than 22.4R3; * 23.2-EVO versions earlier than 23.2R2. • https://supportportal.juniper.net/JSA75726 • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 8.7EPSS: 0%CPEs: 16EXPL: 0CVE-2024-39549 – Junos OS and Junos OS Evolved: Receipt of malformed BGP path attributes leads to a memory leak
https://notcve.org/view.php?id=CVE-2024-39549
A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS). Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd). Memory utilization could be monitored by: user@host> show system memory or show system monitor memory status This issue affects: Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2.

https://notcve.org/view.php?id=CVE-2024-39548
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. • https://supportportal.juniper.net/JSA83010 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2024-39546
A Missing Authorization vulnerability in the Socket Intercept (SI) command file interface of Juniper Networks Junos OS Evolved allows an authenticated, low-privilege local attacker to modify certain files, allowing the attacker to cause any command to execute with root privileges leading to privilege escalation ultimately compromising the system.
