CVE-2018-0008 – Junos OS: commit script may allow unauthenticated root login upon reboot
https://notcve.org/view.php?id=CVE-2018-0008
An unauthenticated root login may allow upon reboot when a commit script is used. A commit script allows a device administrator to execute certain instructions during commit, which is configured under the [system scripts commit] stanza. Certain commit scripts that work without a problem during normal commit may cause unexpected behavior upon reboot which can leave the system in a state where root CLI login is allowed without a password due to the system reverting to a "safe mode" authentication state. Lastly, only logging in physically to the console port as root, with no password, will work. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D71 on SRX; 12.3X48 versions prior to 12.3X48-D55 on SRX; 14.1 versions prior to 14.1R9; 14.1X53 versions prior to 14.1X53-D40 on QFX, EX; 14.2 versions prior to 14.2R7-S9, 14.2R8; 15.1 versions prior to 15.1F5-S7, 15.1F6-S8, 15.1R5-S6, 15.1R6; 15.1X49 versions prior to 15.1X49-D110 on SRX; 15.1X53 versions prior to 15.1X53-D232 on QFX5200/5110; 15.1X53 versions prior to 15.1X53-D49, 15.1X53-D470 on NFX; 15.1X53 versions prior to 15.1X53-D65 on QFX10K; 16.1 versions prior to 16.1R2. • http://www.securitytracker.com/id/1040186 https://kb.juniper.net/JSA10835 https://lists.apache.org/thread.html/rfb87e0bf3995e7d560afeed750fac9329ff5f1ad49da365129b7f89e%40%3Ccommits.cxf.apache.org%3E • CWE-287: Improper Authentication •
CVE-2018-0009 – SRX Series: Firewall bypass vulnerability when UUID with leading zeros is configured.
https://notcve.org/view.php?id=CVE-2018-0009
On Juniper Networks SRX series devices, firewall rules configured to match custom application UUIDs starting with zeros can match all TCP traffic. Due to this issue, traffic that should have been blocked by other rules is permitted to flow through the device resulting in a firewall bypass condition. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D71 on SRX series; 12.3X48 versions prior to 12.3X48-D55 on SRX series; 15.1X49 versions prior to 15.1X49-D100 on SRX series. En los dispositivos Juniper de la serie SRX, las reglas de firewall configuradas para hacer "match" en UUID de aplicación personalizados que empiezan con ceros pueden hacer "match" en todo el tráfico TCP. A causa de este problema, al tráfico que se debería haber bloqueado por otras reglas se le permite fluir a través del dispositivo, resultando en una condición de omisión de firewall. • http://www.securityfocus.com/bid/102491 http://www.securitytracker.com/id/1040187 https://kb.juniper.net/JSA10836 •
CVE-2018-0002 – MX series, SRX series: Junos OS: Denial of service vulnerability in Flowd on devices with ALG enabled.
https://notcve.org/view.php?id=CVE-2018-0002
On SRX Series and MX Series devices with a Service PIC with any ALG enabled, a crafted TCP/IP response packet processed through the device results in memory corruption leading to a flowd daemon crash. Sustained crafted response packets lead to repeated crashes of the flowd daemon which results in an extended Denial of Service condition. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D60 on SRX series; 12.3X48 versions prior to 12.3X48-D35 on SRX series; 14.1 versions prior to 14.1R9 on MX series; 14.2 versions prior to 14.2R8 on MX series; 15.1X49 versions prior to 15.1X49-D60 on SRX series; 15.1 versions prior to 15.1R5-S8, 15.1F6-S9, 15.1R6-S4, 15.1R7 on MX series; 16.1 versions prior to 16.1R6 on MX series; 16.2 versions prior to 16.2R3 on MX series; 17.1 versions prior to 17.1R2-S4, 17.1R3 on MX series. No other Juniper Networks products or platforms are affected by this issue. En dispositivos de las series SRX y MX con un Service PIC con cualquier ALG habilitado, un paquete de respuesta TCP/IP manipulado procesado por el dispositivo resulta en una corrupción de memoria que provoca que el demonio flowd se cierre de manera inesperada. • http://www.securitytracker.com/id/1040178 https://kb.juniper.net/JSA10829 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-10620 – SRX Series: Antivirus updates are downloaded without verification
https://notcve.org/view.php?id=CVE-2017-10620
Juniper Networks Junos OS on SRX series devices do not verify the HTTPS server certificate before downloading anti-virus updates. This may allow a man-in-the-middle attacker to inject bogus signatures to cause service disruptions or make the device not detect certain types of attacks. Affected Junos OS releases are: 12.1X46 prior to 12.1X46-D71; 12.3X48 prior to 12.3X48-D55; 15.1X49 prior to 15.1X49-D110; Juniper Networks Junos OS en dispositivos de la serie SRX no verifica el certificado del servidor HTTPS antes de descargar actualizaciones de antivirus. Esto puede permitir que un atacante Man-in-the-Middle (MitM) inyecte firmas falsas para causar disrupciones de servicio o hacer que el dispositivo no detecte ciertos tipos de ataques. Las distribuciones afectadas Junos OS son: 12.1X46 anteriores a 12.1X46-D71; 12.3X48 anteriores a 12.3X48-D55; 15.1X49 anteriores a 15.1X49-D110. • https://kb.juniper.net/JSA10822 • CWE-295: Improper Certificate Validation •
CVE-2017-2341 – Junos OS: VM to host privilege escalation in platforms with Junos OS running in a virtualized environment.
https://notcve.org/view.php?id=CVE-2017-2341
An insufficient authentication vulnerability on platforms where Junos OS instances are run in a virtualized environment, may allow unprivileged users on the Junos OS instance to gain access to the host operating environment, and thus escalate privileges. Affected releases are Juniper Networks Junos OS 14.1X53 prior to 14.1X53-D40 on QFX5110, QFX5200, QFX10002, QFX10008, QFX10016, EX4600 and NFX250; 15.1 prior to 15.1R5 on EX4600; 15.1X49 prior to 15.1X49-D70 on vSRX, SRX1500, SRX4100, SRX4200; 16.1 prior to 16.1R2 on EX4600, ACX5000 series. This issue does not affect vMX. No other Juniper Networks products or platforms are affected by this issue. Una vulnerabilidad de autenticación insuficiente en plataformas donde las instancias de Junos OS se ejecutan en un entorno virtualizado, puede permitir que los usuarios sin privilegios de la instancia de Junos OS alcanzar acceso al entorno operativo del host y, por lo tanto, escalar los privilegios. • http://www.securitytracker.com/id/1038893 https://kb.juniper.net/JSA10787 • CWE-287: Improper Authentication •
