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...
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...
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...
Input validation
An input validation vulnerability exists in Juniper Networks Junos OS, allowing an attacker to crash the srxpfe process, causing a Denial of Service DoS through the use of specific maintenance commands. The srxpfe process restarts automatically, but continuous execution of the commands could lead...
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...
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...
Design/Logic Flaw
The Juniper Device Manager JDM container, used by the disaggregated Junos OS architecture on Juniper Networks NFX350 Series devices, stores password hashes in the world-readable file /etc/passwd. This is not a security best current practice as it can allow an attacker with access to the local...
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
Receipt of a specifically malformed NDP packet sent from the local area network LAN to a device running Juniper Networks Junos OS Evolved can cause the ndp process to crash, resulting in a Denial of Service DoS. The process automatically restarts without intervention, but a continuous receipt of...
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...
Design/Logic Flaw
On Juniper Networks MX Series and EX9200 Series, in a certain condition the IPv6 Distributed Denial of Service DDoS protection might not take affect when it reaches the threshold condition. The DDoS protection allows the device to continue to function while it is under DDoS attack, protecting bot...
Cross site scripting
Insufficient Cross-Site Scripting XSS protection in Juniper Networks J-Web and web based HTTP/HTTPS services allows an unauthenticated attacker to hijack the target user's HTTP/HTTPS session and perform administrative actions on the Junos device as the targeted user. This issue only affects Junip...
Design/Logic Flaw
On Juniper Networks Junos OS devices, receipt of a malformed IPv6 packet may cause the system to crash and restart vmcore. This issue can be trigged by a malformed IPv6 packet destined to the Routing Engine. An attacker can repeatedly send the offending packet resulting in an extended Denial of...
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...
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,...
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...
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...
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
On Juniper Networks Junos OS and Junos OS Evolved devices, BGP session flapping can lead to a routing process daemon RPD crash and restart, limiting the attack surface to configured BGP peers. This issue only affects devices with BGP damping in combination with accepted-prefix-limit configuration...
CVE-2020-1688 Junos OS: SRX and NFX Series: Insufficient Web API private key protection
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...
