Design/Logic Flaw

A vulnerability in the BGP FlowSpec implementation may cause a Juniper Networks Junos OS device to terminate an established BGP session upon receiving a specific BGP FlowSpec advertisement. The BGP NOTIFICATION message that terminates an established BGP session is sent toward the peer device that...

Hardcoded credentials

A Use of Hard-coded Credentials vulnerability exists in the NFX250 Series for the vSRX Virtual Network Function VNF instance, which allows an attacker to take control of the vSRX VNF instance if they have the ability to access an administrative service e.g. SSH on the VNF, either locally, or...

Design/Logic Flaw

A vulnerability in Juniper Networks SRX Series device configured as a Junos OS Enforcer device may allow a user to access network resources that are not permitted by a UAC policy. This issue might occur when the IP address range configured in the Infranet Controller IC is configured as an IP...

Design/Logic Flaw

When an attacker sends a specific crafted Ethernet Operation, Administration, and Maintenance Ethernet OAM packet to a target device, it may improperly handle the incoming malformed data and fail to sanitize this incoming data resulting in an overflow condition. This overflow condition in Juniper...

Race condition

A race condition vulnerability on Juniper Network Junos OS devices may cause the routing protocol daemon RPD process to crash and restart while processing a BGP NOTIFICATION message. This issue affects Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S6; 16.2 versions prior to 16.2R2-S11;...

Default credentials

Due to insufficient server-side login attempt limit enforcement, a vulnerability in the SSH login service of Juniper Networks Juniper Advanced Threat Prevention JATP Series and Virtual JATP vJATP devices allows an unauthenticated, remote attacker to perform multiple login attempts in excess of th...

Design/Logic Flaw

A vulnerability in Juniper Networks Junos OS Evolved may allow an attacker to cause a Denial of Service DoS by sending a high rate of specific packets to the device, resulting in a pfemand process crash. The pfemand process is responsible for packet forwarding on the device. By continuously sendi...

Memory corruption

The kernel memory usage represented as "temp" via 'show system virtual-memory' may constantly increase when Integrated Routing and Bridging IRB is configured with multiple underlay physical interfaces, and one interface flaps. This memory leak can affect running daemons processes, leading to an...

Design/Logic Flaw

A vulnerability in Juniper Networks Junos OS on vMX and MX150 devices may allow an attacker to cause a Denial of Service DoS by sending specific packets requiring special processing in microcode that the flow cache can't handle, causing the riot forwarding daemon to crash. By continuously sending...

Input validation

This issue occurs on Juniper Networks Junos OS devices which do not support Advanced Forwarding Interface AFI / Advanced Forwarding Toolkit AFT. Devices using AFI and AFT are not exploitable to this issue. An improper initialization of memory in the packet forwarding architecture in Juniper...

Information disclosure

Juniper Networks Junos OS uses the 128.0.0.0/2 subnet for internal communications between the RE and PFEs. It was discovered that packets utilizing these IP addresses may egress an EX4300 switch, leaking configuration information such as heartbeats, kernel versions, etc. out to the Internet,...

Authorization

The factory configuration for vMX installations, as shipped, includes default credentials for the root account. Without proper modification of these default credentials by the administrator, an attacker could exploit these credentials and access the vMX instance without authorization. This issue...

Authentication flaw

On Juniper Networks EX and QFX Series, an authentication bypass vulnerability may allow a user connected to the console port to login as root without any password. This issue might only occur in certain scenarios: • At the first reboot after performing device factory reset using the command...

CVE-2020-1639

Affected product: Juniper Networks Junos OS. Issue: processing of specially crafted Ethernet OAM packets causes the CFM daemon to overflow due to improper handling of malformed data, leading to a Denial of Service (DoS) by crashing the CFM process; continued packet receipt can extend the DoS. Aff...

CVE-2020-1637 Junos OS: SRX Series: Unified Access Control (UAC) bypass vulnerability

A vulnerability in Juniper Networks SRX Series device configured as a Junos OS Enforcer device may allow a user to access network resources that are not permitted by a UAC policy. This issue might occur when the IP address range configured in the Infranet Controller IC is configured as an IP...

CVE-2020-1638

The CVE-2020-1638 issue affects Juniper Junos OS and Junos OS Evolved FPCs in MX Series (MPC10E/MPC11E) and PTX10001/PTX10003 lines, where processing a specific IPv4 packet can trigger an FPC restart and drop all traffic via the FPC, causing a sustained DoS. Affected ranges include: Junos OS on M...

CVE-2020-1638 Junos OS & Junos OS Evolved: A specific IPv4 packet can lead to FPC restart.

The FPC Flexible PIC Concentrator of Juniper Networks Junos OS and Junos OS Evolved may restart after processing a specific IPv4 packet. Only packets destined to the device itself, successfully reaching the RE through existing edge and control plane filtering, will be able to cause the FPC restar...

CVE-2020-1637

CVE-2020-1637 concerns a bypass of Unified Access Control (UAC) on Juniper Networks SRX Series running Junos OS Enforcer. The root cause is when the Infranet Controller IP range is configured as an IP address range instead of an IP address/netmask, which can allow a user to access network resourc...

CVE-2020-1634

CVE-2020-1634 affects Junos OS on High-End SRX Series: certain configurations allow a SPC receiving genuine multicast traffic to core, causing all FPCs in the chassis to reset and resulting in a Denial of Service. Affected versions include Junos OS 12.3X48-D80 and later, up to but not including 1...

CVE-2020-1630 Junos OS: Privilege escalation vulnerability in dual REs, VC or HA cluster may allow unauthorized configuration change.
