CVSS: 7.5EPSS: 0%CPEs: 52EXPL: 0CVE-2019-0056 – Junos OS: MX Series: An MPC10 Denial of Service (DoS) due to OSPF states transitioning to Down, causes traffic to stop forwarding through the device.
https://notcve.org/view.php?id=CVE-2019-0056
This issue only affects devices with three (3) or more MPC10's installed in a single chassis with OSPF enabled and configured on the device. An Insufficient Resource Pool weakness allows an attacker to cause the device's Open Shortest Path First (OSPF) states to transition to Down, resulting in a Denial of Service (DoS) attack. This attack requires a relatively large number of specific Internet Mixed (IMIXed) types of genuine and valid IPv6 packets to be transferred by the attacker in a relatively short period of time, across three or more PFE's on the device at the same time. Continued receipt of the traffic sent by the attacker will continue to cause OSPF to remain in the Down starting state, or flap between other states and then again to Down, causing a persistent Denial of Service. This attack will affect all IPv4, and IPv6 traffic served by the OSPF routes once the OSPF states transition to Down. • https://kb.juniper.net/JSA10954 • CWE-410: Insufficient Resource Pool •
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: 7.4EPSS: 0%CPEs: 41EXPL: 0CVE-2019-0054 – Junos OS: SRX Series: An attacker may be able to perform Man-in-the-Middle (MitM) attacks during app-id signature updates.
https://notcve.org/view.php?id=CVE-2019-0054
An Improper Certificate Validation weakness in the SRX Series Application Identification (app-id) signature update client of Juniper Networks Junos OS allows an attacker to perform Man-in-the-Middle (MitM) attacks which may compromise the integrity and confidentiality of the device. This issue affects: Juniper Networks Junos OS 15.1X49 versions prior to 15.1X49-D120 on SRX Series devices. No other versions of Junos OS are affected. Una debilidad de Comprobación de Certificado Inapropiada en el cliente de actualización de firma de SRX Series Application Identification (app-id) de Juniper Networks Junos OS, permite a un atacante realizar ataques de tipo Man-in-the-Middle (MitM) que pueden comprometer la integridad y confidencialidad del dispositivo . Este problema afecta a: Juniper Networks Junos OS versiones 15.1X49 anteriores a 15.1X49-D120 en dispositivos de la Serie SRX. • https://kb.juniper.net/JSA10952 https://www.juniper.net/documentation/en_US/junos/topics/topic-map/security-application-identification-overview.html • CWE-295: Improper Certificate Validation CWE-300: Channel Accessible by Non-Endpoint •
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 •
CVSS: 7.5EPSS: 0%CPEs: 64EXPL: 0CVE-2019-0050 – Junos OS: SRX1500: Denial of service due to crash of srxpfe process under heavy traffic conditions.
https://notcve.org/view.php?id=CVE-2019-0050
Under certain heavy traffic conditions srxpfe process can crash and result in a denial of service condition for the SRX1500 device. Repeated crashes of the srxpfe can result in an extended denial of service condition. The SRX device may fail to forward traffic when this condition occurs. Affected releases are Juniper Networks Junos OS: 15.1X49 versions prior to 15.1X49-D170 on SRX1500; 17.3 versions prior to 17.3R3-S7 on SRX1500; 17.4 versions prior to 17.4R2-S8, 17.4R3 on SRX1500; 18.1 versions prior to 18.1R3-S8 on SRX1500; 18.2 versions prior to 18.2R3 on SRX1500; 18.3 versions prior to 18.3R2 on SRX1500; 18.4 versions prior to 18.4R2 on SRX1500. Bajo determinadas condiciones de tráfico pesado, el proceso srxpfe puede bloquearse y provocar una denegación de servicio para el dispositivo SRX1500. • https://kb.juniper.net/JSA10972 •
