CVSS: 7.5EPSS: 0%CPEs: 50EXPL: 0CVE-2019-0037 – Junos OS: jdhcpd crash upon receipt of crafted DHCPv6 solicit message
https://notcve.org/view.php?id=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 causing a sustained Denial of Service (DoS) to both IPv4 and IPv6 clients. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D171, 15.1X49-D180; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496; 16.1 versions prior to 16.1R3-S10, 16.1R7-S4; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S2; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D30; 18.3 versions prior to 18.3R1-S2. This issue does not affect Junos OS releases prior to 15.1. En un entorno de Protocolo de configuración dinámica de host versión 6 (DHCPv6), el demonio jdhcpd puede bloquearse y reiniciarse al recibir ciertos mensajes de solicitud de DHCPv6 de un cliente DHCPv6. • http://www.securityfocus.com/bid/107894 https://kb.juniper.net/JSA10926 •
CVSS: 9.8EPSS: 0%CPEs: 109EXPL: 0CVE-2019-0036 – Junos OS: Firewall filter terms named "internal-1" and "internal-2" being ignored
https://notcve.org/view.php?id=CVE-2019-0036
When configuring a stateless firewall filter in Junos OS, terms named using the format "internal-n" (e.g. "internal-1", "internal-2", etc.) are silently ignored. No warning is issued during configuration, and the config is committed without error, but the filter criteria will match all packets leading to unexpected results. Affected releases are Juniper Networks Junos OS: All versions prior to and including 12.3; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D161, 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D69; 16.1 versions prior to 16.1R7-S4, 16.1R7-S5; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S7, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4; 18.2 versions prior to 18.2R1-S5, 18.2R2-S1; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3; 18.4 versions prior to 18.4R1-S1, 18.4R1-S2. Cuando se configura un filtro de cortafuegos sin estado en Junos OS, los términos nombrados con el formato "internal-n" (por ejemplo, "internal-1", "internal-2", etc.) se ignoran en silencio. • https://kb.juniper.net/JSA10925 • CWE-284: Improper Access Control CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 7.2EPSS: 0%CPEs: 84EXPL: 0CVE-2019-0035 – Junos OS: 'set system ports console insecure' allows root password recovery on OAM volumes
https://notcve.org/view.php?id=CVE-2019-0035
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 a possible administrative bypass with physical access to the console. OAM volumes (e.g. flash drives) are typically instantiated as /dev/gpt/oam, or /oam for short. Password recovery, changing the root password from a console, should not have been allowed from an insecure console. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D160; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D68; 16.1 versions prior to 16.1R3-S10, 16.1R6-S6, 16.1R7-S3; 16.1X65 versions prior to 16.1X65-D49; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S6, 17.4R2-S2; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S2. • https://kb.juniper.net/JSA10924 • CWE-501: Trust Boundary Violation CWE-522: Insufficiently Protected Credentials •
CVSS: 7.5EPSS: 0%CPEs: 17EXPL: 0CVE-2019-0033 – SRX Series: A remote attacker may cause a high CPU Denial of Service to the device when proxy ARP is configured.
https://notcve.org/view.php?id=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-D25 prior to 12.1X46-D71, 12.1X46-D73 on SRX Series; 12.3X48 versions prior to 12.3X48-D50 on SRX Series; 15.1X49 versions prior to 15.1X49-D75 on SRX Series.

CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2019-0031 – Junos OS: jdhcpd daemon memory consumption Denial of Service when receiving specific IPv6 DHCP packets.
https://notcve.org/view.php?id=CVE-2019-0031
Specific IPv6 DHCP packets received by the jdhcpd daemon will cause a memory resource consumption issue to occur on a Junos OS device using the jdhcpd daemon configured to respond to IPv6 requests. Once started, memory consumption will eventually impact any IPv4 or IPv6 request serviced by the jdhcpd daemon, thus creating a Denial of Service (DoS) condition to clients requesting and not receiving IP addresses. Additionally, some clients which were previously holding IPv6 addresses will not have their IPv6 Identity Association (IA) address and network tables agreed upon by the jdhcpd daemon after the failover event occurs, which leads to more than one interface, and multiple IP addresses, being denied on the client. Affected releases are Juniper Networks Junos OS: 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R2. Los paquetes DHCP IPv6 específicos recibidos por el demonio jdhcpd causarán un problema de consumo de recursos de memoria en un dispositivo Junos OS que utiliza el demonio jdhcpd configurado para responder a las peticiones de IPv6. • http://www.securityfocus.com/bid/107874 https://kb.juniper.net/JSA10920 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
