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...

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...

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...

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...

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...

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

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-2020-1638 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 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-2020-1634 Junos OS: High-End SRX Series: Multicast traffic might cause all FPCs to reset.

On High-End SRX Series devices, in specific configurations and when specific networking events or operator actions occur, an SPC receiving genuine multicast traffic may core. Subsequently, all FPCs in a chassis may reset causing a Denial of Service. This issue affects both IPv4 and IPv6. This iss...

CVE-2020-1630

CVE-2020-1630 affects Juniper Networks Junos OS on devices configured with dual Routing Engines, Virtual Chassis, or HA clusters.
