A password management issue exists where the Organization authentication username and password were stored in plaintext in log files. A locally authenticated attacker who is able to access these stored plaintext credentials can use them to login to the Organization. Affected products are: Juniper...

Stack overflow

A certain sequence of valid BGP or IPv6 BFD packets may trigger a stack based buffer overflow in the Junos OS Packet Forwarding Engine manager FXPC process on QFX5000 series, EX4300, EX4600 devices. This issue can result in a crash of the fxpc daemon or may potentially lead to remote code...

CVE-2019-0040

On Junos OS, rpcbind should only be listening to port 111 on the internal routing instance IRI. External packets destined to port 111 should be dropped. Due to an information leak vulnerability, responses were being generated from the source address of the management interface e.g. fxp0 thus...

CVE-2019-0033

A firewall bypass vulnerability in the proxy ARP service of Juniper Networks Junos OS allows an attacker to cause a high CPU condition leading to a Denial of Service DoS. This issue affects only IPv4. Affected releases are Juniper Networks Junos OS: 12.1X46 versions above and including 12.1X46-D2...

CVE-2019-0042

Juniper Identity Management Service JIMS for Windows versions prior to 1.1.4 may send an incorrect message to associated SRX services gateways. This may allow an attacker with physical access to an existing domain connected Windows system to bypass SRX firewall policies, or trigger a Denial of...

CVE-2019-0037

In a Dynamic Host Configuration Protocol version 6 DHCPv6 environment, the jdhcpd daemon may crash and restart upon receipt of certain DHCPv6 solicit messages received from a DHCPv6 client. By continuously sending the same crafted packet, an attacker can repeatedly crash the jdhcpd process causin...

Design/Logic Flaw

When BGP tracing is enabled an incoming BGP message may cause the Junos OS routing protocol daemon rpd process to crash and restart. While rpd restarts after a crash, repeated crashes can result in an extended DoS condition. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to...

Design/Logic Flaw

When "set system ports console insecure" is enabled, root login is disallowed for Junos OS as expected. However, the root password can be changed using "set system root-authentication plain-text-password" on systems booted from an OAM Operations, Administration, and Maintenance volume, leading to...

CVE-2019-0037 Junos OS: jdhcpd crash upon receipt of crafted DHCPv6 solicit message

In a Dynamic Host Configuration Protocol version 6 DHCPv6 environment, the jdhcpd daemon may crash and restart upon receipt of certain DHCPv6 solicit messages received from a DHCPv6 client. By continuously sending the same crafted packet, an attacker can repeatedly crash the jdhcpd process causin...

CVE-2019-0039

CVE-2019-0039 affects Junos OS where REST API is enabled, enabling brute-force login attempts due to a high default connection limit. Publicly documented details list affected Junos OS versions (e.g., 14.1X53 before 14.1X53-D49; 15.1 family before various 15.x builds; up to 18.3R1-S1), with remed...

CVE-2019-0035

CVE-2019-0035 describes an administrative bypass on Juniper Networks Junos OS. When the insecure console port setting is enabled, an attacker with physical access can change the root password on systems booted from an OAM volume using the command set system root-authentication plain-text-password...

CVE-2019-0028 Junos OS: RPD process crashes due to specific BGP peer restarts condition.

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 to crash and restart. By simulating a...

CVE-2019-0041 Junos OS: EX4300-MP Series: IP transit traffic can reach the control plane via loopback interface.

On EX4300-MP Series devices with any lo0 filters applied, transit network traffic may reach the control plane via loopback interface lo0. The device may fail to forward such traffic. This issue affects Juniper Networks Junos OS 18.2 versions prior to 18.2R1-S2, 18.2R2 on EX4300-MP Series. This...

CVE-2019-0043 Junos OS: RPD process crashes upon receipt of a specific SNMP packet

In MPLS environments, receipt of a specific SNMP packet may cause the routing protocol daemon RPD process to crash and restart. By continuously sending a specially crafted SNMP packet, an attacker can repetitively crash the RPD process causing prolonged denial of service. No other Juniper Network...

CVE-2019-0043

CVE-2019-0043 describes a denial-of-service vulnerability in Junos OS where receipt of a specially crafted SNMP packet can cause the RPD process to crash and restart, leading to prolonged DoS.
