Design/Logic Flaw

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

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,...

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 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...

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-2020-1637

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.

A privilege escalation vulnerability in Juniper Networks Junos OS devices configured with dual Routing Engines RE, Virtual Chassis VC or high-availability cluster may allow a local authenticated low-privileged user with access to the shell to perform unauthorized configuration modification. This...

CVE-2020-1630

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