CVSS: 7.5EPSS: 0%CPEs: 183EXPL: 0CVE-2023-44186 – Junos OS and Junos OS Evolved: RPD crash when attempting to send a very long AS PATH to a non-4-byte-AS capable BGP neighbor
https://notcve.org/view.php?id=CVE-2023-44186
An Improper Handling of Exceptional Conditions vulnerability in AS PATH processing of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a BGP update message with an AS PATH containing a large number of 4-byte ASes, leading to a Denial of Service (DoS). Continued receipt and processing of these BGP updates will create a sustained Denial of Service (DoS) condition. This issue is hit when the router has Non-Stop Routing (NSR) enabled, has a non-4-byte-AS capable BGP neighbor, receives a BGP update message with a prefix that includes a long AS PATH containing large number of 4-byte ASes, and has to advertise the prefix towards the non-4-byte-AS capable BGP neighbor. Note: NSR is not supported on the SRX Series and is therefore not affected by this vulnerability. This issue affects: Juniper Networks Junos OS: * All versions prior to 20.4R3-S8; * 21.1 versions 21.1R1 and later; * 21.2 versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R2-S2, 22.3R3-S1; * 22.4 versions prior to 22.4R2-S1, 22.4R3. Juniper Networks Junos OS Evolved * All versions prior to 20.4R3-S8-EVO; * 21.1 versions 21.1R1-EVO and later; * 21.2 versions prior to 21.2R3-S6-EVO; * 21.3 versions prior to 21.3R3-S5-EVO; * 21.4 versions prior to 21.4R3-S5-EVO; * 22.1 versions prior to 22.1R3-S4-EVO; * 22.2 versions prior to 22.2R3-S2-EVO; * 22.3 versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO; * 22.4 versions prior to 22.4R2-S1-EVO, 22.4R3-EVO. Una vulnerabilidad de Improper Handling of Exceptional Conditions en el procesamiento AS PATH de Juniper Networks Junos OS y Junos OS Evolved permite a un atacante enviar un mensaje de actualización de BGP con un AS PATH que contiene una gran cantidad de AS de 4 bytes, lo que lleva a una Denegación de Servicio ( DoS). La recepción y el procesamiento continuo de estas actualizaciones de BGP crearán una condición sostenida de Denegación de Servicio (DoS). Este problema se produce cuando el router tiene habilitado Non-Stop Routing (NSR), tiene un vecino BGP que no es de 4 bytes con capacidad AS, recibe un mensaje de actualización de BGP con un prefijo que incluye un AS PATH largo que contiene una gran cantidad de 4 bytes. • https://supportportal.juniper.net/JSA73150 • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2023-4481
An Improper Input Validation 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). When certain specific crafted BGP UPDATE messages are received over an established BGP session, one BGP session may be torn down with an UPDATE message error, or the issue may propagate beyond the local system which will remain non-impacted, but may affect one or more remote systems. This issue is exploitable remotely as the crafted UPDATE message can propagate through unaffected systems and intermediate BGP speakers. Continuous receipt of the crafted 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. • https://kb.juniper.net/JSA72510 https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic-map/bgp-error-messages.html https://www.rfc-editor.org/rfc/rfc4271 https://www.rfc-editor.org/rfc/rfc7606 • CWE-20: Improper Input Validation •
