CVSS: 7.5EPSS: 0%CPEs: 301EXPL: 0CVE-2019-0068 – Junos OS: SRX Series: Denial of Service vulnerability in flowd due to multicast packets
https://notcve.org/view.php?id=CVE-2019-0068
The SRX flowd process, responsible for packet forwarding, may crash and restart when processing specific multicast packets. By continuously sending the specific multicast packets, an attacker can repeatedly crash the flowd process causing a sustained Denial of Service. This issue affects Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D90; 15.1X49 versions prior to 15.1X49-D180; 17.3 versions; 17.4 versions prior to 17.4R2-S5, 17.4R3; 18.1 versions prior to 18.1R3-S6; 18.2 versions prior to 18.2R2-S4, 18.2R3; 18.3 versions prior to 18.3R2-S1, 18.3R3; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R1-S1, 19.1R2. El proceso flowd SRX, responsable del reenvío de paquetes, puede bloquearse y reiniciarse cuando se procesan paquetes de multidifusión específicos. Mediante el envío de manera continua de los paquetes de multidifusión específicos, un atacante puede bloquear repetidamente el proceso flowd causando una Denegación de Servicio sostenida. • https://kb.juniper.net/JSA10968 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2019-0057
An improper authorization weakness in Juniper Networks Junos OS allows a local authenticated attacker to bypass regular security controls to access the Junos Device Manager (JDM) application and take control of the system. This issue affects: Juniper Networks Junos OS versions prior to 18.2R1, 18.2X75-D5. Una debilidad de autorización inapropiada en Juniper Networks Junos OS, permite a un atacante autenticado local omitir los controles de seguridad regulares para acceder a la aplicación Junos Device Manager (JDM) y tomar el control del sistema.

CVSS: 7.5EPSS: 0%CPEs: 135EXPL: 0CVE-2019-0055 – Junos OS: SRX Series: An attacker may cause flowd to crash by sending certain valid SIP traffic to a device with SIP ALG enabled.
https://notcve.org/view.php?id=CVE-2019-0055
A vulnerability in the SIP ALG packet processing service of Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the device by sending specific types of valid SIP traffic to the device. In this case, the flowd process crashes and generates a core dump while processing SIP ALG traffic. Continued receipt of these valid SIP packets will result in a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D61, 12.3X48-D65 on SRX Series; 15.1X49 versions prior to 15.1X49-D130 on SRX Series; 17.3 versions prior to 17.3R3 on SRX Series; 17.4 versions prior to 17.4R2 on SRX Series. Una vulnerabilidad en el servicio de procesamiento de paquetes ALG SIP de Juniper Networks Junos OS, permite a un atacante causar una Denegación de servicio (DoS) al dispositivo mediante el envío de tipos específicos de tráfico SIP válido hacia el dispositivo. • https://kb.juniper.net/JSA10953 https://www.juniper.net/documentation/en_US/junos/topics/topic-map/security-sip-alg.html • CWE-130: Improper Handling of Length Parameter Inconsistency •
CVSS: 7.5EPSS: 0%CPEs: 119EXPL: 0CVE-2019-0051 – SRX5000 Series: Denial of Service vulnerability in SSL-Proxy feature.
https://notcve.org/view.php?id=CVE-2019-0051
SSL-Proxy feature on SRX devices fails to handle a hardware resource limitation which can be exploited by remote SSL/TLS servers to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition. For this issue to occur, clients protected by the SRX device must initiate a connection to the malicious server. This issue affects: Juniper Networks Junos OS on SRX5000 Series: 12.3X48 versions prior to 12.3X48-D85; 15.1X49 versions prior to 15.1X49-D180; 17.3 versions prior to 17.3R3-S7; 17.4 versions prior to 17.4R2-S6, 17.4R3; 18.1 versions prior to 18.1R3-S8; 18.2 versions prior to 18.2R3; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R2. La funcionalidad proxy SSL en dispositivos SRX no puede manejar una limitación de recursos de hardware que puede ser explotada por servidores SSL/TLS remotos para bloquear el demonio flowd. • https://kb.juniper.net/JSA10973 • CWE-755: Improper Handling of Exceptional Conditions •
