On MX Series, when the SIP ALG is enabled, receipt of a certain malformed SIP packet may crash the MS-PIC component on MS-MIC or MS-MPC. By continuously sending a crafted SIP packet, an attacker can repeatedly bring down MS-PIC on MS-MIC/MS-MPC causing a susta…

QFX5200 and QFX10002 devices that have been shipped with Junos OS 15.1X53-D21, 15.1X53-D30, 15.1X53-D31, 15.1X53-D32, 15.1X53-D33 and 15.1X53-D60 or have been upgraded to these releases using the .bin or .iso images may contain an unintended additional Open Ne…

On Juniper Networks SRX series devices, firewall rules configured to match custom application UUIDs starting with zeros can match all TCP traffic. Due to this issue, traffic that should have been blocked by other rules is permitted to flow through the device r…

Juniper Networks Junos OS uses the 128.0.0.0/2 subnet for internal communications between the RE and PFEs. It was discovered that packets utilizing these IP addresses may egress an EX4300 switch, leaking configuration information such as heartbeats, kernel ver…

An improper interpretation conflict of certain data between certain software components within the Juniper Networks Junos OS devices does not allow certain traffic to pass through the device upon receipt from an ingress interface filtering certain specific typ…

On High-End SRX Series devices, in specific configurations and when specific networking events or operator actions occur, an SPC receiving genuine multicast traffic may core. Subsequently, all FPCs in a chassis may reset causing a Denial of Service. This issue…

Multiple cross-site scripting (XSS) vulnerabilities in the J-Web interface in Juniper JUNOS 8.5R1.14 allow remote authenticated users to inject arbitrary web script or HTML via (1) the JEXEC_OUTID parameter in a JEXEC_MODE_RELAY_OUTPUT action to the jexec prog…

Multiple cross-site scripting (XSS) vulnerabilities in the J-Web interface in Juniper JUNOS 8.5R1.14 allow remote authenticated users to inject arbitrary web script or HTML via the host parameter to (1) the pinghost program, reachable through the diagnose prog…

A sustained sequence of different types of normal transit traffic can trigger a high CPU consumption denial of service condition in the Junos OS register and schedule software interrupt handler subsystem when a specific command is issued to the device. This af…

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 D…

A firewall bypass vulnerability in the host based firewall of Juniper Networks Junos Space versions prior to 16.1R1 may permit certain crafted packets, representing a network integrity risk.

A path traversal vulnerability in the Juniper Networks SRX and vSRX Series may allow an authenticated J-web user to read sensitive system files. This issue affects Juniper Networks Junos OS on SRX and vSRX Series: 19.3 versions prior to 19.3R2-S6, 19.3R3-S1; 1…

An Improper Input Validation vulnerability in J-Web of Juniper Networks Junos OS allows a locally authenticated J-Web attacker to escalate their privileges to root over the target device. This issue affects: Juniper Networks Junos OS All versions prior to 18.3…

Juniper Junos before 11.4R11, 12.1 before 12.1R9, 12.2 before 12.2R7, 12.3R4 before 12.3R4-S3, 13.1 before 13.1R4, 13.2 before 13.2R2, and 13.3 before 13.3R1, as used in MX Series and T4000 routers, allows remote attackers to cause a denial of service (PFE res…

On Junos devices with the BGP graceful restart helper mode enabled or the BGP graceful restart mechanism enabled, a BGP session restart on a remote peer that has the graceful restart mechanism enabled may cause the local routing protocol daemon (RPD) process t…

A local file inclusion vulnerability in Juniper Networks Junos Space Network Management Platform may allow an authenticated user to retrieve files from the system.

Receipt of specially crafted UDP/IP packets over MPLS may be able to bypass a stateless firewall filter. The crafted UDP packets must be encapsulated and meet a very specific packet format to be classified in a way that bypasses IP firewall filter rules. The p…
