CVE-2018-0061 – Junos OS: Denial of service in telnetd
https://notcve.org/view.php?id=CVE-2018-0061
A denial of service vulnerability in the telnetd service on Junos OS allows remote unauthenticated users to cause high CPU usage which may affect system performance. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D81 on SRX Series; 12.3 versions prior to 12.3R12-S11; 12.3X48 versions prior to 12.3X48-D80 on SRX Series; 15.1 versions prior to 15.1R7; 15.1X49 versions prior to 15.1X49-D150, 15.1X49-D160 on SRX Series; 15.1X53 versions prior to 15.1X53-D59 on EX2300/EX3400 Series; 15.1X53 versions prior to 15.1X53-D68 on QFX10K Series; 15.1X53 versions prior to 15.1X53-D235 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D495 on NFX Series; 16.1 versions prior to 16.1R4-S12, 16.1R6-S6, 16.1R7; 16.2 versions prior to 16.2R2-S7, 16.2R3; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R2-S6, 17.2R3; 17.2X75 versions prior to 17.2X75-D100; 17.3 versions prior to 17.3R2-S4, 17.3R3; 17.4 versions prior to 17.4R1-S5, 17.4R2; 18.2X75 versions prior to 18.2X75-D5. Una vulnerabilidad de denegación de servicio (DoS) en el servicio telnetd de Junos OS permite que usuarios remotos no autenticados provoquen un alto uso de la CPU, lo que podría afectar al rendimiento del sistema. Las versiones afectadas de Juniper Networks Junos OS son: 12.1X46 en versiones anteriores a la 12.1X46-D81 en SRX Series; 12.3 en versiones anteriores a la 12.3R12-S11; 12.3X48 en versiones anteriores a la 12.3X48-D80 en SRX Series; 15.1 en versiones anteriores a la 15.1R7; 15.1X49 en versiones anteriores a la 15.1X49-D150, 15.1X49-D160 en SRX Series; 15.1X53 en versiones anteriores a la 15.1X53-D59 en EX2300/EX3400 Series; 15.1X53 en versiones anteriores a la 15.1X53-D68 en QFX10K Series; 15.1X53 en versiones anteriores a la 15.1X53-D235 en QFX5200/QFX5110 Series; 15.1X53 en versiones anteriores a la 15.1X53-D495 en NFX Series; 16.1 en versiones anteriores a la 16.1R4-S12, 16.1R6-S6, 16.1R7; 16.2 en versiones anteriores a la 16.2R2-S7, 16.2R3; 17.1 en versiones anteriores a la 17.1R2-S9, 17.1R3; 17.2 en versiones anteriores a la 17.2R2-S6, 17.2R3; 17.2X75 en versiones anteriores a la 17.2X75-D100; 17.3 en versiones anteriores a la 17.3R2-S4, 17.3R3; 17.4 en versiones anteriores a la 17.4R1-S5, 17.4R2 y 18.2X75 en versiones anteriores a la 18.2X75-D5. • http://www.securitytracker.com/id/1041859 https://kb.juniper.net/JSA10896 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-0052 – Junos OS: Unauthenticated remote root access possible when RSH service is enabled
https://notcve.org/view.php?id=CVE-2018-0052
If RSH service is enabled on Junos OS and if the PAM authentication is disabled, a remote unauthenticated attacker can obtain root access to the device. RSH service is disabled by default on Junos. There is no documented CLI command to enable this service. However, an undocumented CLI command allows a privileged Junos user to enable RSH service and disable PAM, and hence expose the system to unauthenticated root access. When RSH is enabled, the device is listing to RSH connections on port 514. • http://www.securitytracker.com/id/1041853 https://kb.juniper.net/JSA10886 • CWE-287: Improper Authentication •
CVE-2018-0055 – Junos OS: jdhcpd process crash during processing of specially crafted DHCPv6 message
https://notcve.org/view.php?id=CVE-2018-0055
Receipt of a specially crafted DHCPv6 message destined to a Junos OS device configured as a DHCP server in a Broadband Edge (BBE) environment may result in a jdhcpd daemon crash. The daemon automatically restarts without intervention, but a continuous receipt of crafted DHCPv6 packets could leaded to an extended denial of service condition. This issue only affects Junos OS 15.1 and later. Earlier releases are unaffected by this issue. Devices are only vulnerable to the specially crafted DHCPv6 message if DHCP services are configured. • http://www.securitytracker.com/id/1041856 https://kb.juniper.net/JSA10889 • CWE-20: Improper Input Validation •
