Improper Handling of Exceptional Conditions in Ethernet interface frame processing of Juniper Networks Junos OS allows an attacker to send specially crafted frames over the local Ethernet segment, causing the interface to go into a down state, resulting in a Denial of Service DoS condition. The...

Hardcoded credentials

Juniper Networks Contrail Cloud CC releases prior to 13.6.0 have RabbitMQ service enabled by default with hardcoded credentials. The messaging services of RabbitMQ are used when coordinating operations and status information among Contrail services. An attacker with access to an administrative...

Design/Logic Flaw

An Out-of-bounds Read vulnerability in the processing of specially crafted LLDP frames by the Layer 2 Control Protocol Daemon l2cpd of Juniper Networks Junos OS and Junos OS Evolved may allow an attacker to cause a Denial of Service DoS, or may lead to remote code execution RCE. Continued receipt...

Design/Logic Flaw

In a Segment Routing ISIS SR-ISIS/MPLS environment, on Juniper Networks Junos OS and Junos OS Evolved devices, configured with ISIS Flexible Algorithm for Segment Routing and sensor-based statistics, a flap of a ISIS link in the network, can lead to a routing process daemon RPD crash and restart,...

Race condition

When user-defined ARP Policer is configured and applied on one or more Aggregated Ethernet AE interface units, a Time-of-check Time-of-use TOCTOU Race Condition vulnerability between the Device Control Daemon DCD and firewall process dfwd daemons of Juniper Networks Junos OS allows an attacker to...

CVE-2021-0295

The CVE-2021-0295 issue affects Juniper Networks Junos OS on QFX10K Series switches (e.g., QFX10002/10008/10016). It’s caused by DVMRP packets looping on a multi-homed ESI when VXLAN is configured, leading to a packet forwarding loop that triggers a partial DoS. Affected versions include multiple...

CVE-2021-0294 Junos OS: QFX5000 Series and EX4600 Series: Enhanced storm control might not work leading to partial Denial of Service

A vulnerability in Juniper Networks Junos OS, which only affects the release 18.4R2-S5, where a function is inconsistently implemented on Juniper Networks Junos QFX5000 Series and EX4600 Series, and if "storm-control enhanced" is configured, can lead to the enhanced storm control filter group not...

CVE-2021-0294

CVE-2021-0294 affects Junos OS 18.4R2-S5 on QFX5000 Series and EX4600 Series; when storm-control enhanced is configured, the enhanced storm control filter group may not be installed, causing storm control to fail and potentially high CPU usage or packet loss from excessive broadcast/unknown unica...
