Design/Logic Flaw

The management daemon MGD is responsible for all configuration and management operations in Junos OS. The Junos CLI communicates with MGD over an internal unix-domain socket and is granted special permission to open this protected mode socket. Due to a misconfiguration of the internal socket, a...

Memory corruption

A memory leak vulnerability in the of Juniper Networks Junos OS allows an attacker to cause a Denial of Service DoS to the device by sending specific commands from a peered BGP host and having those BGP states delivered to the vulnerable device. This issue affects: Juniper Networks Junos OS: 18.1...

Input validation

An Improper Input Validation weakness allows a malicious local attacker to elevate their permissions to take control of other portions of the NFX platform they should not be able to access, and execute commands outside their authorized scope of control. This leads to the attacker being able to ta...

Design/Logic Flaw

An unexpected status return value weakness in the Next-Generation Multicast VPN NG-mVPN service of Juniper Networks Junos OS allows attacker to cause a Denial of Service DoS condition and core the routing protocol daemon rpd process when a specific malformed IPv4 packet is received by the device...

Design/Logic Flaw

On SRX5000 Series devices, if 'set security zones security-zone tcp-rst' is configured, the flowd process may crash when a specific TCP packet is received by the device and triggers a new session. The process restarts automatically. However, receipt of a constant stream of these TCP packets may...

Design/Logic Flaw

A vulnerability in the SIP ALG packet processing service of Juniper Networks Junos OS allows an attacker to cause a Denial of Service DoS to the device by sending specific types of valid SIP traffic to the device. In this case, the flowd process crashes and generates a core dump while processing...

Design/Logic Flaw

The flowd process, responsible for forwarding traffic in SRX Series services gateways, may crash and restart when processing specific transit IP packets through an IPSec tunnel. Continued processing of these packets may result in an extended Denial of Service DoS condition. This issue only occurs...

Design/Logic Flaw

When an MX Series Broadband Remote Access Server BRAS is configured as a Broadband Network Gateway BNG with DHCPv6 enabled, jdhcpd might crash when receiving a specific crafted DHCP response message on a subscriber interface. The daemon automatically restarts without intervention, but continuous...

Race condition

SSL-Proxy feature on SRX devices fails to handle a hardware resource limitation which can be exploited by remote SSL/TLS servers to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition. For this issue to occur, clients protected by the...

Code injection

Receipt of a specific link-local IPv6 packet destined to the RE may cause the system to crash and restart vmcore. By continuously sending a specially crafted IPv6 packet, an attacker can repeatedly crash the system causing a prolonged Denial of Service DoS. This issue affects Juniper Networks Jun...

Path traversal

A path traversal vulnerability in NFX150 Series and QFX10K Series, EX9200 Series, MX Series and PTX Series devices with Next-Generation Routing Engine NG-RE allows a local authenticated user to read sensitive system files. This issue only affects NFX150 Series and QFX10K Series, EX9200 Series, MX...

Authentication flaw

Veriexec is a kernel-based file integrity subsystem in Junos OS that ensures only authorized binaries are able to be executed. Due to a flaw in specific versions of Junos OS, affecting specific EX Series platforms, the Veriexec subsystem will fail to initialize, in essence disabling file integrit...

Authorization

An improper authorization weakness in Juniper Networks Junos OS allows a local authenticated attacker to bypass regular security controls to access the Junos Device Manager JDM application and take control of the system. This issue affects: Juniper Networks Junos OS versions prior to 18.2R1,...

Design/Logic Flaw

A vulnerability in the srxpfe process on Protocol Independent Multicast PIM enabled SRX series devices may lead to crash of the srxpfe process and an FPC reboot while processing PIM messages. Sustained receipt of these packets may lead to an extended denial of service condition. Affected releases...

Design/Logic Flaw

A vulnerability in the Veriexec subsystem of Juniper Networks Junos OS allowing an attacker to fully compromise the host system. A local authenticated user can elevate privileges to gain full control of the system even if they are specifically denied access to perform certain actions. This issue...

Code injection

This issue only affects devices with three 3 or more MPC10's installed in a single chassis with OSPF enabled and configured on the device. An Insufficient Resource Pool weakness allows an attacker to cause the device's Open Shortest Path First OSPF states to transition to Down, resulting in a...

Session fixation

A session fixation vulnerability in J-Web on Junos OS may allow an attacker to use social engineering techniques to fix and hijack a J-Web administrators web session and potentially gain administrative access to the device. This issue affects: Juniper Networks Junos OS 12.3 versions prior to...

CVE-2019-0073 Junos OS: PKI key pairs are exported with insecure file permissions

The PKI keys exported using the command "run request security pki key-pair export" on Junos OS may have insecure file permissions. This may allow another user on the Junos OS device with shell access to read them. This issue affects: Juniper Networks Junos OS 15.1X49 versions prior to 15.1X49-D18...

CVE-2019-0074 Junos OS: NFX150 Series, QFX10K Series, EX9200 Series, MX Series, PTX Series: Path traversal vulnerability in NFX150 and NG-RE leads to information disclosure.
