CVE-2019-0041 – Junos OS: EX4300-MP Series: IP transit traffic can reach the control plane via loopback interface.
https://notcve.org/view.php?id=CVE-2019-0041
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 issue does not affect any other EX series devices. En los dispositivos de la serie EX4300-MP con cualquier filtro lo0 aplicado, el tráfico de la red de tránsito puede alcanzar el plano de control por medio de la interfaz de bucle invertido (lo0). • https://kb.juniper.net/JSA10933 • CWE-284: Improper Access Control •
CVE-2019-0040 – Junos OS: Specially crafted packets sent to port 111 on any interface triggers responses from the management interface
https://notcve.org/view.php?id=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 disclosing internal addressing and existence of the management interface itself. A high rate of crafted packets destined to port 111 may also lead to a partial Denial of Service (DoS). Note: Systems with fxp0 disabled or unconfigured are not vulnerable to this issue. • http://www.securityfocus.com/bid/107902 https://kb.juniper.net/JSA10929 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2019-0039 – Junos OS: Login credentials are vulnerable to brute force attacks through the REST API
https://notcve.org/view.php?id=CVE-2019-0039
If REST API is enabled, the Junos OS login credentials are vulnerable to brute force attacks. The high default connection limit of the REST API may allow an attacker to brute-force passwords using advanced scripting techniques. Additionally, administrators who do not enforce a strong password policy can increase the likelihood of success from brute force attacks. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D49; 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-D495, 15.1X53-D591, 15.1X53-D69; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S3; 16.1X65 versions prior to 16.1X65-D49; 16.2 versions prior to 16.2R2-S7; 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-S2; 17.4 versions prior to 17.4R1-S6, 17.4R2-S2; 18.1 versions prior to 18.1R2-S4, 18.1R3-S1; 18.2 versions prior to 18.2R1-S5; 18.2X75 versions prior to 18.2X75-D30; 18.3 versions prior to 18.3R1-S1. Si la API REST está activada, las credenciales de inicio de sesión en Junos OS son vulnerables a los ataques por fuerza bruta. • http://www.securityfocus.com/bid/107899 https://kb.juniper.net/JSA10928 • CWE-307: Improper Restriction of Excessive Authentication Attempts •
CVE-2019-0038 – SRX Series: Crafted packets destined to fxp0 management interface on SRX340/SRX345 devices can lead to DoS
https://notcve.org/view.php?id=CVE-2019-0038
Crafted packets destined to the management interface (fxp0) of an SRX340 or SRX345 services gateway may create a denial of service (DoS) condition due to buffer space exhaustion. This issue only affects the SRX340 and SRX345 services gateways. No other products or platforms are affected by this vulnerability. Affected releases are Juniper Networks Junos OS: 15.1X49 versions prior to 15.1X49-D160 on SRX340/SRX345; 17.3 on SRX340/SRX345; 17.4 versions prior to 17.4R2-S3, 17.4R3 on SRX340/SRX345; 18.1 versions prior to 18.1R3-S1 on SRX340/SRX345; 18.2 versions prior to 18.2R2 on SRX340/SRX345; 18.3 versions prior to 18.3R1-S2, 18.3R2 on SRX340/SRX345. This issue does not affect Junos OS releases prior to 15.1X49 on any platform. • http://www.securityfocus.com/bid/107873 https://kb.juniper.net/JSA10927 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-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 •
