CVSS: 5.3EPSS: 1%CPEs: 152EXPL: 1CVE-2023-36847 – Juniper Junos OS EX Series Missing Authentication for Critical Function Vulnerability
https://notcve.org/view.php?id=CVE-2023-36847
A Missing Authentication for Critical Function vulnerability in Juniper Networks Junos OS on EX Series allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity. With a specific request to installAppPackage.php that doesn't require authentication an attacker is able to upload arbitrary files via J-Web, leading to a loss of integrity for a certain part of the file system, which may allow chaining to other vulnerabilities. This issue affects Juniper Networks Junos OS on EX Series: * 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-S4; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S1; * 22.3 versions prior to 22.3R2-S2, 22.3R3; * 22.4 versions prior to 22.4R2-S1, 22.4R3. "Una vulnerabilidad de falta de autenticación para funciones críticas en Juniper Networks Junos OS en la serie EX permite a un atacante no autenticado basado en red causar un impacto limitado en la integridad del sistema de archivos. Con una solicitud específica a installAppPackage.php que no requiere autenticación, un atacante puede cargar archivos arbitrarios a través de J-Web, lo que provoca una pérdida de integridad de una parte determinada del sistema de archivos, que puede permitir el encadenamiento con otras vulnerabilidades. Este problema afecta al sistema operativo Junos de Juniper Networks en la serie EX: * Todas las versiones anteriores a 20.4R3-S8; * 21.1: versiones 21.1R1 y posteriores; * 21.2: versiones anteriores a 21.2R3-S6; * 21.3: versiones anteriores a 21.3R3-S5; * 21.4: versiones anteriores a 21.4R3-S4; * 22.1: versiones anteriores a 22.1R3-S3; * 22.2: versiones anteriores a 22.2R3-S1; * 22.3: versiones anteriores a 22.3R2-S2, 22.3R3; * 22.4: versiones anteriores a 22.4R2-S1, 22.4R3."

CVSS: 5.5EPSS: 0%CPEs: 184EXPL: 0CVE-2022-22234 – Junos OS: EX2300 and EX3400 Series: One of more SFPs might become unavailable when the system is very busy
https://notcve.org/view.php?id=CVE-2022-22234
An Improper Preservation of Consistency Between Independent Representations of Shared State vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). If the device is very busy for example while executing a series of show commands on the CLI one or more SFPs might not be detected anymore. The system then changes its state to "unplugged" which is leading to traffic impact and at least a partial DoS. Once the system is less busy the port states return to their actual value. Indicators of compromise are log messages about unplugged SFPs and corresponding syspld messages without any physical or environmental cause. • https://kb.juniper.net/JSA69890 • CWE-1250: Improper Preservation of Consistency Between Independent Representations of Shared State •
CVSS: 7.8EPSS: 0%CPEs: 200EXPL: 0CVE-2022-22221 – Junos OS: SRX and EX Series: Local privilege escalation flaw in "download" functionality
https://notcve.org/view.php?id=CVE-2022-22221
An Improper Neutralization of Special Elements vulnerability in the download manager of Juniper Networks Junos OS on SRX Series and EX Series allows a locally authenticated attacker with low privileges to take full control over the device. One aspect of this vulnerability is that the attacker needs to be able to execute any of the "request ..." or "show system download ..." commands. This issue affects Juniper Networks Junos OS on SRX Series and EX Series: All versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2, 20.4R3-S3; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R2-S2, 21.2R3; 21.3 versions prior to 21.3R2, 21.3R3; 21.4 versions prior to 21.4R1-S1, 21.4R2. Una vulnerabilidad de Neutralización Inapropiada de Elementos Especiales en el administrador de descargas del Sistema Operativo Junos de Juniper Networks en las series SRX y EX permite a un atacante autenticado localmente con bajos privilegios tomar el control total del dispositivo. Uno de los aspectos de esta vulnerabilidad es que el atacante debe ser capaz de ejecutar cualquiera de los comandos "request ..." o "show system download ...". • https://kb.juniper.net/JSA69725 •
