Race condition

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...

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,...

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...

Code injection

A local, authenticated user with shell can obtain the hashed values of login passwords and shared secrets via the EvoSharedObjStore. This issue affects all versions of Junos OS Evolved prior to 19.1R1...

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...

A local, authenticated user with shell can obtain the hashed values of login passwords via configd streamer log. This issue affects all versions of Junos OS Evolved prior to 19.3R1...

Privilege escalation

A privilege escalation vulnerability in Juniper Networks QFX10K Series, EX9200 Series, MX Series, and PTX Series with Next-Generation Routing Engine NG-RE, allows a local authenticated high privileged user to access the underlying WRL host. This issue only affects QFX10K Series with NG-RE, EX9200...

A local, authenticated user with shell can obtain the hashed values of login passwords via configd traces. This issue affects all versions of Junos OS Evolved prior to 19.3R1...

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...

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...

Design/Logic Flaw

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...

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...

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...

CVE-2020-1639 Junos OS: A crafted Ethernet OAM packet received by Junos may cause the Ethernet OAM connectivity fault management process (CFM) to core.

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...
