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 •
