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 •
CVE-2017-10604 – Junos OS: SRX Series: Cluster configuration sync failures occur if the root user account is locked out
https://notcve.org/view.php?id=CVE-2017-10604
When the device is configured to perform account lockout with a defined period of time, any unauthenticated user attempting to log in as root with an incorrect password can trigger a lockout of the root account. When an SRX Series device is in cluster mode, and a cluster sync or failover operation occurs, then there will be errors associated with synch or failover while the root account is locked out. Administrators can confirm if the root account is locked out via the following command root@device> show system login lockout user root User Lockout start Lockout end root 1995-01-01 01:00:01 PDT 1995-11-01 01:31:01 PDT Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D65 on SRX series; 12.3X48 prior to 12.3X48-D45 on SRX series; 15.1X49 prior to 15.1X49-D75 on SRX series. Cuando el dispositivo está configurado para realizar el bloqueo de la cuenta con un período de tiempo definido, cualquier usuario no autenticado que intente iniciar sesión como root con una contraseña incorrecta puede desencadenar un bloqueo de la cuenta root. Cuando un dispositivo de la serie SRX está en modo clúster y se produce una operación de sincronización o conmutación por error del clúster, entonces habrá errores asociados con la sincronización o la conmutación por error mientras la cuenta root está bloqueada. • http://www.securitytracker.com/id/1038886 https://kb.juniper.net/JSA10806 • CWE-307: Improper Restriction of Excessive Authentication Attempts •
CVE-2017-10605 – Junos: SRX Series denial of service vulnerability in flowd due to crafted DHCP packet
https://notcve.org/view.php?id=CVE-2017-10605
On all vSRX and SRX Series devices, when the DHCP or DHCP relay is configured, specially crafted packet might cause the flowd process to crash, halting or interrupting traffic from flowing through the device(s). Repeated crashes of the flowd process may constitute an extended denial of service condition for the device(s). If the device is configured in high-availability, the RG1+ (data-plane) will fail-over to the secondary node. If the device is configured in stand-alone, there will be temporary traffic interruption until the flowd process is restored automatically. Sustained crafted packets may cause the secondary failover node to fail back, or fail completely, potentially halting flowd on both nodes of the cluster or causing flip-flop failovers to occur. • http://www.securitytracker.com/id/1038891 https://kb.juniper.net/JSA10789 • CWE-20: Improper Input Validation •
CVE-2017-2345 – Junos: snmpd denial of service upon receipt of crafted SNMP packet
https://notcve.org/view.php?id=CVE-2017-2345
On Junos OS devices with SNMP enabled, a network based attacker with unfiltered access to the RE can cause the Junos OS snmpd daemon to crash and restart by sending a crafted SNMP packet. Repeated crashes of the snmpd daemon can result in a partial denial of service condition. Additionally, it may be possible to craft a malicious SNMP packet in a way that can result in remote code execution. SNMP is disabled in Junos OS by default. Junos OS devices with SNMP disabled are not affected by this issue. • http://www.securityfocus.com/bid/99567 http://www.securitytracker.com/id/1038903 https://kb.juniper.net/JSA10793 • CWE-20: Improper Input Validation •
CVE-2017-2346 – MS-MPC or MS-MIC crash when passing large fragmented traffic through an ALG
https://notcve.org/view.php?id=CVE-2017-2346
An MS-MPC or MS-MIC Service PIC may crash when large fragmented packets are passed through an Application Layer Gateway (ALG). Repeated crashes of the Service PC can result in an extended denial of service condition. The issue can be seen only if NAT or stateful-firewall rules are configured with ALGs enabled. This issue was caused by the code change for PR 1182910 in Junos OS 14.1X55-D30, 14.1X55-D35, 14.2R7, 15.1R5, and 16.1R2. No other versions of Junos OS and no other Juniper Networks products or platforms are affected by this issue. • http://www.securitytracker.com/id/1038895 https://kb.juniper.net/JSA10794 •
