NFX Series devices using Juniper Networks Junos OS are susceptible to a local code execution vulnerability thereby allowing an attacker to elevate their privileges via the Junos Device Management Daemon (JDMD) process. This issue affects Juniper Networks Junos OS on NFX Series: 18.1 version 18.1R1 and later versions prior to 18.2R3-S5; 18.3 versions prior to 18.3R2-S4, 18.3R3-S3; 18.4 versions prior to 18.4R2-S5, 18.4R3-S4; 19.1 versions prior to 19.1R1-S3, 19.1R2; 19.2 versions prior to 19.2R1-S5, 19.2R2. This issue does not affect: Juniper Networks Junos OS versions prior to 18.1R1. This issue does not affect the JDMD as used by Junos Node Slicing such as External Servers use in conjunction with Junos Node Slicing and In-Chassis Junos Node Slicing on MX480, MX960, MX2008, MX2010, MX2020. Los dispositivos de la Serie NFX que utilizan Juniper Networks Junos OS son susceptibles a una vulnerabilidad de ejecución de código local, permitiendo a un atacante elevar sus privilegios mediante el proceso Junos Device Management Daemon (JDMD). • https://github.com/orangecertcc/security-research/security/advisories/GHSA-gr7j-26pv-5v57 https://kb.juniper.net/JSA11145 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

A NULL Pointer Dereference vulnerability in the Captive Portal Content Delivery (CPCD) services daemon (cpcd) of Juniper Networks Junos OS on MX Series with MS-PIC, MS-SPC3, MS-MIC or MS-MPC allows an attacker to send malformed HTTP packets to the device thereby causing a Denial of Service (DoS), crashing the Multiservices PIC Management Daemon (mspmand) process thereby denying users the ability to login, while concurrently impacting other mspmand services and traffic through the device. Continued receipt and processing of these malformed packets will create a sustained Denial of Service (DoS) condition. While the Services PIC is restarting, all PIC services will be bypassed until the Services PIC completes its boot process. An attacker sending these malformed HTTP packets to the device who is not part of the Captive Portal experience is not able to exploit this issue. This issue is not applicable to MX RE-based CPCD platforms. • https://kb.juniper.net/JSA11144 • CWE-476: NULL Pointer Dereference •

In segment routing traffic engineering (SRTE) environments where the BGP Monitoring Protocol (BMP) feature is enable, a vulnerability in the Routing Protocol Daemon (RPD) process of Juniper Networks Junos OS allows an attacker to send a specific crafted BGP update message causing the RPD service to core, creating a Denial of Service (DoS) Condition. Continued receipt and processing of this update message will create a sustained Denial of Service (DoS) condition. This issue affects IPv4 and IPv6 environments. This issue affects: Juniper Networks Junos OS 17.4 versions 17.4R1 and above prior to 17.4R2-S6, 17.4R3; 18.1 versions prior to 18.1R3-S7; 18.2 versions prior to 18.2R2-S6, 18.2R3-S3; 18.3 versions prior to 18.3R1-S7, 18.3R2-S3, 18.3R3; 18.4 versions prior to 18.4R1-S5, 18.4R2-S3, 18.4R3; 19.1 versions prior to 19.1R1-S4, 19.1R2; 19.2 versions prior to 19.2R1-S3, 19.2R2, This issue does not affect Junos OS releases prior to 17.4R1. This issue affects: Juniper Networks Junos OS Evolved 19.2-EVO versions prior to 19.2R2-EVO. • https://kb.juniper.net/JSA11143 •

On SRX Series devices configured with UTM services a buffer overflow vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS may allow an attacker to arbitrarily execute code or commands on the target to take over or otherwise impact the device by sending crafted packets to or through the device. This issue affects: Juniper Networks Junos OS on SRX Series: 15.1X49 versions prior to 15.1X49-D190; 17.4 versions prior to 17.4R2-S9; 17.4R3 and later versions prior to 18.1R3-S9; 18.2 versions prior to 18.2R3-S1; 18.3 versions prior to 18.3R2-S3, 18.3R3; 18.4 versions prior to 18.4R2-S3, 18.4R3; 19.1 versions prior to 19.1R1-S4, 19.1R2; 19.2 versions prior to 19.2R1-S1, 19.2R2. An indicator of compromise can be the following text in the UTM log: RT_UTM: AV_FILE_NOT_SCANNED_PASSED_MT: En los dispositivos de la Serie SRX configurados con servicios UTM, una vulnerabilidad de desbordamiento de búfer en el Packet Forwarding Engine (PFE) de Juniper Networks Junos OS, puede permitir a un atacante ejecutar código o comandos arbitrarios en el objetivo para tomar el control o afectar el dispositivo mediante el envío de paquetes diseñados hacia por medio del dispositivo. Este problema afecta a: Juniper Networks Junos OS en la serie SRX: versiones 15.1X49 anteriores a 15.1X49-D190; versiones 17.4 anteriores a 17.4R2-S9; versiones 17.4R3 y posteriores anteriores a 18.1R3-S9; versiones 18.2 anteriores a 18.2R3-S1; versiones 18.3 anteriores a 18.3R2-S3, 18.3R3; versiones 18.4 anteriores a 18.4R2-S3, 18.4R3; versiones 19.1 anteriores a 19.1R1-S4, 19.1R2; versiones 19.2 anteriores a 19.2R1-S1, 19.2R2. Un indicador de compromiso puede ser el siguiente texto en el registro de UTM: RT_UTM: AV_FILE_NOT_SCANNED_PASSED_MT • https://kb.juniper.net/JSA11142 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

This issue is not applicable to NFX NextGen Software. On NFX Series devices the use of Hard-coded Credentials in Juniper Networks Junos OS allows an attacker to take over any instance of an NFX deployment. This issue is only exploitable through administrative interfaces. This issue affects: Juniper Networks Junos OS versions prior to 19.1R1 on NFX Series. No other platforms besides NFX Series devices are affected. • https://kb.juniper.net/JSA11141 • CWE-798: Use of Hard-coded Credentials •
