Design/Logic Flaw
On Juniper Networks MX Series with MS-MIC or MS-MPC card configured with NAT64 configuration, receipt of a malformed IPv6 packet may crash the MS-PIC component on MS-MIC or MS-MPC. This issue occurs when a multiservice card is translating the malformed IPv6 packet to IPv4 packet. An unauthenticat...
Authentication flaw
On Juniper Networks SRX Series and NFX Series, a local authenticated user with access to the shell may obtain the Web API service private key that is used to provide encrypted communication between the Juniper device and the authenticator services. Exploitation of this vulnerability may allow an...
Authentication flaw
When SAML authentication is enabled, Juniper Networks Mist Cloud UI might incorrectly handle child elements in SAML responses, allowing a remote attacker to modify a valid SAML response without invalidating its cryptographic signature to bypass SAML authentication security controls. This issue...
Design/Logic Flaw
On Juniper Networks EX4300-MP Series, EX4600 Series and QFX5K Series deployed in Ethernet VPN EVPN-Virtual Extensible LAN VXLAN configuration, receipt of a stream of specific VXLAN encapsulated layer 2 frames can cause high CPU load, which could lead to network protocol operation issue and traffi...
Race condition
On Juniper Networks Junos OS devices configured with DHCPv6 relay enabled, receipt of a specific DHCPv6 packet might crash the jdhcpd daemon. The jdhcpd daemon automatically restarts without intervention, but continuous receipt of specific crafted DHCP messages will repeatedly crash jdhcpd, leadi...
Design/Logic Flaw
On Juniper Networks EX4300 Series, receipt of a stream of specific IPv4 packets can cause Routing Engine RE high CPU load, which could lead to network protocol operation issue and traffic interruption. This specific packets can originate only from within the broadcast domain where the device is...
Design/Logic Flaw
On Juniper Networks EX2300 Series, receipt of a stream of specific multicast packets by the layer2 interface can cause high CPU load, which could lead to traffic interruption. This issue occurs when multicast packets are received by the layer 2 interface. To check if the device has high CPU load...
Design/Logic Flaw
On Juniper Networks Junos OS devices configured as a DHCP forwarder, the Juniper Networks Dynamic Host Configuration Protocol Daemon jdhcp process might crash when receiving a malformed DHCP packet. This issue only affects devices configured as DHCP forwarder with forward-only option, that forwar...
Memory corruption
On Juniper Networks Junos OS devices, a specific SNMP OID poll causes a memory leak which over time leads to a kernel crash vmcore. Prior to the kernel crash other processes might be impacted, such as failure to establish SSH connection to the device. The administrator can monitor the output of t...
Design/Logic Flaw
On SRX Series devices, a vulnerability in the key-management-daemon kmd daemon of Juniper Networks Junos OS allows an attacker to spoof packets targeted to IPSec peers before a security association SA is established thereby causing a failure to set up the IPSec channel. Sustained receipt of these...
Code injection
When DNS filtering is enabled on Juniper Networks Junos MX Series with one of the following cards MS-PIC, MS-MIC or MS-MPC, an incoming stream of packets processed by the Multiservices PIC Management Daemon mspmand process, responsible for managing "URL Filtering service", may crash, causing the...
Race condition
When DNS filtering is enabled on Juniper Networks Junos MX Series with one of the following cards MS-PIC, MS-MIC or MS-MPC, an incoming stream of packets processed by the Multiservices PIC Management Daemon mspmand process might be bypassed due to a race condition. Due to this vulnerability,...
Authentication flaw
When SAML authentication is enabled, Juniper Networks Mist Cloud UI might incorrectly handle SAML responses, allowing a remote attacker to modify a valid SAML response without invalidating its cryptographic signature to bypass SAML authentication security controls. This issue affects all Juniper...
Design/Logic Flaw
On Juniper Networks Junos OS and Junos OS Evolved platforms with EVPN configured, receipt of specific BGP packets causes a slow memory leak. If the memory is exhausted the rpd process might crash. If the issue occurs, the memory leak could be seen by executing the "show task memory detail | match...
Design/Logic Flaw
When configuring stateless firewall filters in Juniper Networks EX4600 and QFX 5000 Series devices using Virtual Extensible LAN protocol VXLAN, the discard action will fail to discard traffic under certain conditions. Given a firewall filter configuration similar to: family ethernet-switching...
Design/Logic Flaw
On Juniper Networks SRX Series configured with application identification inspection enabled, receipt of specific HTTP traffic can cause high CPU load utilization, which could lead to traffic interruption. Application identification is enabled by default and is automatically turned on when...
Design/Logic Flaw
On Juniper Networks EX4300-MP Series, EX4600 Series and QFX5K Series deployed in a Virtual Chassis configuration, receipt of a stream of specific layer 2 frames can cause high CPU load, which could lead to traffic interruption. This issue does not occur when the device is deployed in Stand Alone...
Input validation
The DHCPv6 Relay-Agent service, part of the Juniper Enhanced jdhcpd daemon shipped with Juniper Networks Junos OS has an Improper Input Validation vulnerability which will result in a Denial of Service DoS condition when a DHCPv6 client sends a specific DHPCv6 message allowing an attacker to...
Default configuration
The system console configuration option 'log-out-on-disconnect' In Juniper Networks Junos OS Evolved fails to log out an active CLI session when the console cable is disconnected. This could allow a malicious attacker with physical access to the console the ability to resume a previous interactiv...
Command injection
On Juniper Networks PTX and QFX Series devices with packet sampling configured using tunnel-observation mpls-over-udp, sampling of a malformed packet can cause the Kernel Routing Table KRT queue to become stuck. KRT is the module within the Routing Process Daemon RPD that synchronized the routing...
