Heap overflow
On Juniper Networks MX Series and EX9200 Series platforms with Trio-based MPC Modular Port Concentrator where Integrated Routing and Bridging IRB interface is configured and it is mapped to a VPLS instance or a Bridge-Domain, certain network events at Customer Edge CE device may cause memory leak...
Command injection
A command injection vulnerability in install package validation subsystem of Juniper Networks Junos OS that may allow a locally authenticated attacker with privileges to execute commands with root privilege. To validate a package in Junos before installation, an administrator executes the command...
Command injection
A command injection vulnerability in the license-check daemon of Juniper Networks Junos OS that may allow a locally authenticated attacker with low privileges to execute commands with root privilege. license-check is a daemon used to manage licenses in Junos OS. To update licenses, a user execute...
Information disclosure
An Information Exposure vulnerability in Juniper Networks Contrail Networking allows a locally authenticated attacker able to read files to retrieve administrator credentials stored in plaintext thereby elevating their privileges over the system. This issue affects: Juniper Networks Contrail...
Design/Logic Flaw
A vulnerability in Juniper Networks Junos OS allows an attacker to cause a Denial of Service DoS to the device by sending certain crafted protocol packets from an adjacent device with invalid payloads to the device. These crafted packets, which should be discarded, are instead replicated and sent...
Memory corruption
On Juniper Networks Junos EX series, QFX Series, MX Series and SRX branch series devices, a memory leak occurs every time the 802.1X authenticator port interface flaps which can lead to other processes, such as the pfex process, responsible for packet forwarding, to crash and restart. An...
Design/Logic Flaw
In an EVPN/VXLAN scenario, if an IRB interface with a virtual gateway address VGA is configured on a PE, a traffic loop may occur upon receipt of specific IP multicast traffic. The traffic loop will cause interface traffic to increase abnormally, ultimately leading to a Denial of Service DoS in...
Input validation
An improper input validation vulnerability in the Routing Protocol Daemon RPD service of Juniper Networks Junos OS allows an attacker to send a malformed RSVP packet when bidirectional LSPs are in use, which when received by an egress router crashes the RPD causing a Denial of Service DoS...
Design/Logic Flaw
The Junos Space Network Management Platform has been found to store shared secrets in a recoverable format that can be exposed through the UI. An attacker who is able to execute arbitrary code in the victim browser for example via XSS or access cached contents may be able to obtain a copy of...
Information disclosure
An Information Exposure vulnerability in J-Web of Juniper Networks Junos OS allows an unauthenticated attacker to elevate their privileges over the target system through opportunistic use of an authenticated users session. This issue affects: Juniper Networks Junos OS 12.3 versions prior to...
Privilege escalation
A local privilege escalation vulnerability in telnetd.real of Juniper Networks Junos OS may allow a locally authenticated shell user to escalate privileges and execute arbitrary commands as root. telnetd.real is shipped with setuid permissions enabled and is owned by the root user, allowing local...
Design/Logic Flaw
In Juniper Networks Junos OS Evolved an attacker sending certain valid BGP update packets may cause Junos OS Evolved to access an uninitialized pointer causing RPD to core leading to a Denial of Service DoS. Continued receipt of these types of valid BGP update packets will cause an extended Denia...
Design/Logic Flaw
When the "Intrusion Detection Service" IDS feature is configured on Juniper Networks MX series with a dynamic firewall filter using IPv6 source or destination prefix, it may incorrectly match the prefix as /32, causing the filter to block unexpected traffic. This issue affects only IPv6 prefixes...
Input validation
An improper check for unusual or exceptional conditions in Juniper Networks Junos OS and Junos OS Evolved Routing Protocol Daemon RPD service allows an attacker to send a valid BGP FlowSpec message thereby causing an unexpected change in the route advertisements within the BGP FlowSpec domain...
Information disclosure
A sensitive information disclosure vulnerability in delta-export configuration utility dexp of Juniper Networks Junos OS may allow a locally authenticated shell user the ability to create and read database files generated by the dexp utility, including password hashes of local users.
