CVE-2018-0031 – Junos OS: Receipt of specially crafted UDP packets over MPLS may bypass stateless IP firewall rules
https://notcve.org/view.php?id=CVE-2018-0031
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 packets themselves do not cause a service interruption (e.g. RPD crash), but receipt of a high rate of UDP packets may be able to contribute to a denial of service attack. This issue only affects processing of transit UDP/IP packets over MPLS, received on an interface with MPLS enabled. • http://www.securitytracker.com/id/1041326 https://kb.juniper.net/JSA10865 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-0024 – Junos OS: A privilege escalation vulnerability exists where authenticated users with shell access can become root
https://notcve.org/view.php?id=CVE-2018-0024
An Improper Privilege Management vulnerability in a shell session of Juniper Networks Junos OS allows an authenticated unprivileged attacker to gain full control of the system. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D45 on SRX Series; 12.3X48 versions prior to 12.3X48-D20 on SRX Series; 12.3 versions prior to 12.3R11 on EX Series; 14.1X53 versions prior to 14.1X53-D30 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100;; 15.1X49 versions prior to 15.1X49-D20 on SRX Series. Una vulnerabilidad de gestión incorrecta de privilegios en una sesión shell de Juniper Networks Junos OS permite que un atacante autenticado sin privilegios obtenga el control total del sistema. Las versiones afectadas son Juniper Networks Junos OS: 12.1X46 en versiones anteriores a la 12.1X46-D45 en SRX Series; 12.3X48 en versiones anteriores a la 12.3X48-D20 en SRX Series; 12.3 en versiones anteriores a la 12.3R11 en EX Series; 14.1X53 en versiones anteriores a la 14.1X53-D30 en EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100 y 15.1X49 en versiones anteriores a la 15.1X49-D20 en SRX Series. • http://www.securityfocus.com/bid/104718 http://www.securitytracker.com/id/1041314 https://kb.juniper.net/JSA10857 • CWE-269: Improper Privilege Management •
CVE-2018-0025 – Junos OS: SRX Series: Credentials exposed when using HTTP and HTTPS Firewall Pass-through User Authentication
https://notcve.org/view.php?id=CVE-2018-0025
When an SRX Series device is configured to use HTTP/HTTPS pass-through authentication services, a client sending authentication credentials in the initial HTTP/HTTPS session is at risk that these credentials may be captured during follow-on HTTP/HTTPS requests by a malicious actor through a man-in-the-middle attack or by authentic servers subverted by malicious actors. FTP, and Telnet pass-through authentication services are not affected. Affected releases are Juniper Networks SRX Series: 12.1X46 versions prior to 12.1X46-D67 on SRX Series; 12.3X48 versions prior to 12.3X48-D25 on SRX Series; 15.1X49 versions prior to 15.1X49-D35 on SRX Series. Cuando un dispositivo SRX Series está configurado para emplear los servicios de autenticación pass-through HTTP/HTTPS, un cliente que envía credenciales de autenticación en la sesión inicial HTTP/HTTPS está en riesgo de que estas credenciales puedan ser capturadas durante peticiones HTTP/HTTPS follow-on por parte de un actor malicioso mediante un ataque Man-in-the-Middle (MitM) o por medio de servidores auténticos subvertidos por actores maliciosos. Los servicios de autenticación pass-through FTP y Telnet no se han visto afectados. • http://www.securityfocus.com/bid/104719 http://www.securitytracker.com/id/1041316 https://kb.juniper.net/JSA10858 https://www.juniper.net/documentation/en_US/junos/topics/concept/firewall-user-authentication-pass-through-understanding.html https://www.juniper.net/documentation/en_US/junos/topics/example/firewall-user-authentication-pass-through-configuring-cli.html https://www.juniper.net/documentation/en_US/junos/topics/example/security-https-traffic-to-trigger-pass-through-authentication-configuring.html • CWE-300: Channel Accessible by Non-Endpoint CWE-319: Cleartext Transmission of Sensitive Information •
CVE-2018-0019 – Junos: Denial of service vulnerability in SNMP MIB-II subagent daemon (mib2d).
https://notcve.org/view.php?id=CVE-2018-0019
A vulnerability in Junos OS SNMP MIB-II subagent daemon (mib2d) may allow a remote network based attacker to cause the mib2d process to crash resulting in a denial of service condition (DoS) for the SNMP subsystem. While a mib2d process crash can disrupt the network monitoring via SNMP, it does not impact routing, switching or firewall functionalities. SNMP is disabled by default on devices running Junos OS. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D76; 12.3 versions prior to 12.3R12-S7, 12.3R13; 12.3X48 versions prior to 12.3X48-D65; 14.1 versions prior to 14.1R9; 14.1X53 versions prior to 14.1X53-D130; 15.1 versions prior to 15.1F2-S20, 15.1F6-S10, 15.1R7; 15.1X49 versions prior to 15.1X49-D130; 15.1X53 versions prior to 15.1X53-D233, 15.1X53-D471, 15.1X53-D472, 15.1X53-D58, 15.1X53-D66; 16.1 versions prior to 16.1R5-S3, 16.1R7; 16.1X65 versions prior to 16.1X65-D47; 16.1X70 versions prior to 16.1X70-D10; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R2-S6, 17.1R3; Una vulnerabilidad en el demonio de subagente SNMP MIB-II (mib2d) de Junos OS podría permitir que un atacante remoto en red provoque que el proceso mib2d se cierre inesperadamente, lo que resulta en una condición de denegación de servicio (DoS) para el subsistema SNMP. Aunque un cierre inesperado del proceso mib2d puede interrumpir la monitorización de red mediante SNMP, no impacta sobre las funcionalidades de enrutamiento, switching o firewall. • http://www.securitytracker.com/id/1040787 https://kb.juniper.net/JSA10847 • CWE-20: Improper Input Validation •
CVE-2018-0018 – SRX Series: A crafted packet may lead to information disclosure and firewall rule bypass during compilation of IDP policies.
https://notcve.org/view.php?id=CVE-2018-0018
On SRX Series devices during compilation of IDP policies, an attacker sending specially crafted packets may be able to bypass firewall rules, leading to information disclosure which an attacker may use to gain control of the target device or other internal devices, systems or services protected by the SRX Series device. This issue only applies to devices where IDP policies are applied to one or more rules. Customers not using IDP policies are not affected. Depending on if the IDP updates are automatic or not, as well as the interval between available updates, an attacker may have more or less success in performing reconnaissance or bypass attacks on the victim SRX Series device or protected devices. ScreenOS with IDP is not vulnerable to this issue. • http://www.securityfocus.com/bid/103748 http://www.securitytracker.com/id/1040786 https://kb.juniper.net/JSA10846 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
