CVSS: 7.5EPSS: 0%CPEs: 177EXPL: 0CVE-2021-0280 – Junos OS: PTX Series, QFX10K Series: Upon receipt of specific packets BFD sessions might flap due to DDoS policer implementation in Packet Forwarding Engine
https://notcve.org/view.php?id=CVE-2021-0280
Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on PTX platforms and QFX10K Series with Paradise (PE) chipset-based line cards, ddos-protection configuration changes made from the CLI will not take effect as expected beyond the default DDoS (Distributed Denial of Service) settings in the Packet Forwarding Engine (PFE). This may cause BFD sessions to flap when a high rate of specific packets are received. Flapping of BFD sessions in turn may impact routing protocols and network stability, leading to a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue affects only the following platforms with Paradise (PE) chipset-based line cards: PTX1000, PTX3000 (NextGen), PTX5000, PTX10008, PTX10016 Series and QFX10002 Series. • https://kb.juniper.net/JSA11184 • CWE-665: Improper Initialization •
CVSS: 8.6EPSS: 0%CPEs: 1EXPL: 0CVE-2021-0279 – Contrail Cloud: Hardcoded credentials for RabbitMQ service
https://notcve.org/view.php?id=CVE-2021-0279
Juniper Networks Contrail Cloud (CC) releases prior to 13.6.0 have RabbitMQ service enabled by default with hardcoded credentials. The messaging services of RabbitMQ are used when coordinating operations and status information among Contrail services. An attacker with access to an administrative service for RabbitMQ (e.g. GUI), can use these hardcoded credentials to cause a Denial of Service (DoS) or have access to unspecified sensitive system information. This issue affects the Juniper Networks Contrail Cloud releases on versions prior to 13.6.0. • https://kb.juniper.net/JSA11183 • CWE-798: Use of Hard-coded Credentials •

https://notcve.org/view.php?id=CVE-2021-0276
A stack-based Buffer Overflow vulnerability in Juniper Networks SBR Carrier with EAP (Extensible Authentication Protocol) authentication configured, allows an attacker sending specific packets causing the radius daemon to crash resulting with a Denial of Service (DoS) or leading to remote code execution (RCE). By continuously sending this specific packets, an attacker can repeatedly crash the radius daemon, causing a sustained Denial of Service (DoS). This issue affects Juniper Networks SBR Carrier: 8.4.1 versions prior to 8.4.1R19; 8.5.0 versions prior to 8.5.0R10; 8.6.0 versions prior to 8.6.0R4. Una vulnerabilidad de Desbordamiento del Búfer en la región stack de la memoria en Juniper Networks SBR Carrier con la autenticación EAP (Extensible Authentication Protocol) configurada, permite a un atacante enviar paquetes específicos causando el bloqueo del demonio radius, resultando en una Denegación de Servicio (DoS) o conllevando a una ejecución de código remota (RCE). Al enviar continuamente estos paquetes específicos, un atacante puede bloquear repetidamente el daemon radius, causando una Denegación de Servicio (DoS) sostenida. • https://kb.juniper.net/JSA11180 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
