CVSS: 6.5EPSS: 0%CPEs: 102EXPL: 0CVE-2018-0003 – Junos OS: A crafted MPLS packet may lead to a kernel crash
https://notcve.org/view.php?id=CVE-2018-0003
A specially crafted MPLS packet received or processed by the system, on an interface configured with MPLS, will store information in the system memory. Subsequently, if this stored information is accessed, this may result in a kernel crash leading to a denial of service. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D71; 12.3 versions prior to 12.3R12-S7; 12.3X48 versions prior to 12.3X48-D55; 14.1 versions prior to 14.1R8-S5, 14.1R9; 14.1X53 versions prior to 14.1X53-D45, 14.1X53-D107; 14.2 versions prior to 14.2R7-S7, 14.2R8; 15.1 versions prior to 15.1F5-S8, 15.1F6-S8, 15.1R5-S6, 15.1R6-S3, 15.1R7; 15.1X49 versions prior to 15.1X49-D100; 15.1X53 versions prior to 15.1X53-D65, 15.1X53-D231; 16.1 versions prior to 16.1R3-S6, 16.1R4-S6, 16.1R5; 16.1X65 versions prior to 16.1X65-D45; 16.2 versions prior to 16.2R2-S1, 16.2R3; 17.1 versions prior to 17.1R2-S2, 17.1R3; 17.2 versions prior to 17.2R1-S3, 17.2R2; 17.2X75 versions prior to 17.2X75-D50. No other Juniper Networks products or platforms are affected by this issue.

CVSS: 10.0EPSS: 0%CPEs: 102EXPL: 0CVE-2018-0007
https://notcve.org/view.php?id=CVE-2018-0007
An unauthenticated network-based attacker able to send a maliciously crafted LLDP packet to the local segment, through a local segment broadcast, may be able to cause a Junos device to enter an improper boundary check condition allowing a memory corruption to occur, leading to a denial of service. Further crafted packets may be able to sustain the denial of service condition. Score: 6.5 MEDIUM (CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Further, if the attacker is authenticated on the target device receiving and processing the malicious LLDP packet, while receiving the crafted packets, the attacker may be able to perform command or arbitrary code injection over the target device thereby elevating their permissions and privileges, and taking control of the device. Score: 7.8 HIGH (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) An unauthenticated network-based attacker able to send a maliciously crafted LLDP packet to one or more local segments, via LLDP proxy / tunneling agents or other LLDP through Layer 3 deployments, through one or more local segment broadcasts, may be able to cause multiple Junos devices to enter an improper boundary check condition allowing a memory corruption to occur, leading to multiple distributed Denials of Services. These Denials of Services attacks may have cascading Denials of Services to adjacent connected devices, impacts network devices, servers, workstations, etc. • http://www.securitytracker.com/id/1040181 https://kb.juniper.net/JSA10830 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 8.2EPSS: 0%CPEs: 176EXPL: 0CVE-2018-0002 – MX series, SRX series: Junos OS: Denial of service vulnerability in Flowd on devices with ALG enabled.
https://notcve.org/view.php?id=CVE-2018-0002
On SRX Series and MX Series devices with a Service PIC with any ALG enabled, a crafted TCP/IP response packet processed through the device results in memory corruption leading to a flowd daemon crash. Sustained crafted response packets lead to repeated crashes of the flowd daemon which results in an extended Denial of Service condition. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D60 on SRX series; 12.3X48 versions prior to 12.3X48-D35 on SRX series; 14.1 versions prior to 14.1R9 on MX series; 14.2 versions prior to 14.2R8 on MX series; 15.1X49 versions prior to 15.1X49-D60 on SRX series; 15.1 versions prior to 15.1R5-S8, 15.1F6-S9, 15.1R6-S4, 15.1R7 on MX series; 16.1 versions prior to 16.1R6 on MX series; 16.2 versions prior to 16.2R3 on MX series; 17.1 versions prior to 17.1R2-S4, 17.1R3 on MX series. No other Juniper Networks products or platforms are affected by this issue. En dispositivos de las series SRX y MX con un Service PIC con cualquier ALG habilitado, un paquete de respuesta TCP/IP manipulado procesado por el dispositivo resulta en una corrupción de memoria que provoca que el demonio flowd se cierre de manera inesperada. • http://www.securitytracker.com/id/1040178 https://kb.juniper.net/JSA10829 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.1EPSS: 0%CPEs: 76EXPL: 0CVE-2018-0004 – Junos OS: Kernel Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0004
A sustained sequence of different types of normal transit traffic can trigger a high CPU consumption denial of service condition in the Junos OS register and schedule software interrupt handler subsystem when a specific command is issued to the device. This affects one or more threads and conversely one or more running processes running on the system. Once this occurs, the high CPU event(s) affects either or both the forwarding and control plane. As a result of this condition the device can become inaccessible in either or both the control and forwarding plane and stops forwarding traffic until the device is rebooted. The issue will reoccur after reboot upon receiving further transit traffic. • http://www.securitytracker.com/id/1040183 https://kb.juniper.net/JSA10832 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.4EPSS: 0%CPEs: 149EXPL: 0CVE-2016-4922 – Junos: Privilege escalation vulnerabilities in Junos CLI
https://notcve.org/view.php?id=CVE-2016-4922
Certain combinations of Junos OS CLI commands and arguments have been found to be exploitable in a way that can allow unauthorized access to the operating system. This may allow any user with permissions to run these CLI commands the ability to achieve elevated privileges and gain complete control of the device. Affected releases are Juniper Networks Junos OS 11.4 prior to 11.4R13-S3; 12.1X46 prior to 12.1X46-D60; 12.1X47 prior to 12.1X47-D45; 12.3 prior to 12.3R12; 12.3X48 prior to 12.3X48-D35; 13.2 prior to 13.2R9; 13.3 prior to 13.3R4-S11, 13.3R9; 14.1 prior to 14.1R4-S12, 14.1R7; 14.1X53 prior to 14.1X53-D28, 14.1X53-D40; 14.1X55 prior to 14.1X55-D35; 14.2 prior to 14.2R3-S10, 14.2R4-S7, 14.2R5; 15.1 prior to 15.1F4, 15.1R3; 15.1X49 prior to 15.1X49-D60; 15.1X53 prior to 15.1X53-D57, 15.1X53-D70. Se encontraron algunas combinaciones de argumentos y comandos CLI de Junos OS explotables de una manera que permite el acceso no autorizado al sistema operativo. Esto puede permitir que cualquier usuario con permisos para ejecutar estos comandos CLI tenga la capacidad para conseguir privilegios elevados y obtener el control total del dispositivo. • http://www.securityfocus.com/bid/93534 http://www.securitytracker.com/id/1037013 https://kb.juniper.net/JSA10763 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
