CVSS: 5.3EPSS: 48%CPEs: 158EXPL: 3CVE-2023-36844 – Juniper Junos OS EX Series PHP External Variable Modification Vulnerability
https://notcve.org/view.php?id=CVE-2023-36844
A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series allows an unauthenticated, network-based attacker to control certain, important environment variables. Using a crafted request an attacker is able to modify certain PHP environment variables leading to partial loss of integrity, which may allow chaining to other vulnerabilities. This issue affects Juniper Networks Junos OS on EX Series: * All versions prior to 20.4R3-S9; * 21.1 versions 21.1R1 and later; * 21.2 versions prior to 21.2R3-S7; * 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 22.3R3-S1; * 22.4 versions prior to 22.4R2-S2, 22.4R3; * 23.2 versions prior to 23.2R1-S1, 23.2R2. Una vulnerabilidad de modificación de variables externas de PHP en J-Web de Juniper Networks Junos OS en la serie EX permite a un atacante no autenticado basado en red controlar ciertas variables de entorno importantes. Mediante una solicitud falsificada, un atacante puede modificar determinadas variables de entorno de PHP, lo que conduce a una pérdida parcial de la integridad, 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-S9; * 21.1: versiones 21.1R1 y posteriores; * 21.2: versiones anteriores a 21.2R3-S7; * 21.3: versiones anteriores a 21.3R3-S5; * 21.4: versiones anteriores a 21.4R3-S5; * 22.1: versiones anteriores a 22.1R3-S4; * 22.2: versiones anteriores a 22.2R3-S2; * 22.3: versiones anteriores a 22.3R3-S1; * 22.4: versiones anteriores a 22.4R2-S2, 22.4R3; * 23.2: versiones anteriores a 23.2R1-S1, 23.2R2. Juniper Junos OS on EX Series contains a PHP external variable modification vulnerability that allows an unauthenticated, network-based attacker to control certain, important environment variables. • https://github.com/watchtowrlabs/juniper-rce_cve-2023-36844?ref=labs.watchtowr.com https://github.com/ThatNotEasy/CVE-2023-36844 http://packetstormsecurity.com/files/174865/Juniper-SRX-Firewall-EX-Switch-Remote-Code-Execution.html https://supportportal.juniper.net/JSA72300 • CWE-473: PHP External Variable Modification •
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: 6.5EPSS: 0%CPEs: 224EXPL: 0CVE-2023-36850 – Junos OS: MX Series: An MPC will crash upon receipt of a malformed CFM packet.
https://notcve.org/view.php?id=CVE-2023-36850
An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Connectivity Fault Management(CFM) module of Juniper Networks Junos OS on MX Series(except MPC10, MPC11 and LC9600) allows an adjacent attacker on the local broadcast domain to cause a Denial of Service(DoS). Upon receiving a malformed CFM packet, the MPC crashes. Continued receipt of these packets causes a sustained denial of service. This issue can only be triggered when CFM hasn't been configured. This issue affects: Juniper Networks Junos OS All versions prior to 19.1R3-S10 on MX Series; 19.2 versions prior to 19.2R3-S7 on MX Series; 19.3 versions prior to 19.3R3-S8 on MX Series; 19.4 versions prior to 19.4R3-S12 on MX Series; 20.1 version 20.1R1 and later versions on MX Series; 20.2 versions prior to 20.2R3-S7 on MX Series; 20.3 version 20.3R1 and later versions on MX Series; 20.4 versions prior to 20.4R3-S7 on MX Series; 21.1 versions prior to 21.1R3-S5 on MX Series; 21.2 versions prior to 21.2R3-S4 on MX Series; 21.3 versions prior to 21.3R3-S4 on MX Series; 21.4 versions prior to 21.4R3-S3 on MX Series; 22.1 versions prior to 22.1R3-S2 on MX Series; 22.2 versions prior to 22.2R3 on MX Series; 22.3 versions prior to 22.3R2, 22.3R3 on MX Series; 22.4 versions prior to 22.4R2 on MX Series. • https://supportportal.juniper.net/JSA71661 • CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input •
CVSS: 6.5EPSS: 0%CPEs: 230EXPL: 0CVE-2023-36848 – Junos OS: MX Series: The FPC will crash on receiving a malformed CFM packet
https://notcve.org/view.php?id=CVE-2023-36848
An Improper Handling of Undefined Values vulnerability in the periodic packet management daemon (PPMD) of Juniper Networks Junos OS on MX Series(except MPC10, MPC11 and LC9600) allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). When a malformed CFM packet is received, it leads to an FPC crash. Continued receipt of these packets causes a sustained denial of service. This vulnerability occurs only when CFM has been configured on the interface. This issue affects Juniper Networks Junos OS: versions prior to 19.1R3-S10 on MX Series; 19.2 versions prior to 19.2R3-S7 on MX Series; 19.3 versions prior to 19.3R3-S8 on MX Series; 19.4 versions prior to 19.4R3-S12 on MX Series; 20.1 version 20.1R1 and later versions on MX Series; 20.2 versions prior to 20.2R3-S8 on MX Series; 20.3 version 20.3R1 and later versions on MX Series; 20.4 versions prior to 20.4R3-S7 on MX Series; 21.1 versions prior to 21.1R3-S5 on MX Series; 21.2 versions prior to 21.2R3-S5 on MX Series; 21.3 versions prior to 21.3R3-S4 on MX Series; 21.4 versions prior to 21.4R3-S4 on MX Series; 22.1 versions prior to 22.1R3-S3 on MX Series; 22.2 versions prior to 22.2R3-S1 on MX Series; 22.3 versions prior to 22.3R3 on MX Series; 22.4 versions prior to 22.4R1-S2, 22.4R2 on MX Series. • https://supportportal.juniper.net/JSA71659 • CWE-232: Improper Handling of Undefined Values •
