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.

SNMPv3 HMAC verification in (1) Net-SNMP 5.2.x before 5.2.4.1, 5.3.x before 5.3.2.1, and 5.4.x before 5.4.1.1; (2) UCD-SNMP; (3) eCos; (4) Juniper Session and Resource Control (SRC) C-series 1.0.0 through 2.0.0; (5) NetApp (aka Network Appliance) Data ONTAP 7.3RC1 and 7.3RC2; (6) SNMP Research before 16.2; (7) multiple Cisco IOS, CatOS, ACE, and Nexus products; (8) Ingate Firewall 3.1.0 and later and SIParator 3.1.0 and later; (9) HP OpenView SNMP Emanate Master Agent 15.x; and possibly other products relies on the client to specify the HMAC length, which makes it easier for remote attackers to bypass SNMP authentication via a length value of 1, which only checks the first byte.

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. This issue is not exploitable on platforms where Junos release is based on FreeBSD 10+. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D77 on SRX Series; 12.3 versions prior to 12.3R12-S10; 12.3X48 versions prior to 12.3X48-D75 on SRX Series; 14.1X53 versions prior to 14.1X53-D47 on QFX/EX Series; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D131, 15.1X49-D140 on SRX Series; 15.1X53 versions prior to 15.1X53-D59 on EX2300/EX3400 Series; 15.1X53 versions prior to 15.1X53-D67 on QFX10K Series; 15.1X53 versions prior to 15.1X53-D233 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D471, 15.1X53-D490 on NFX Series; 16.1 versions prior to 16.1R3-S9, 16.1R4-S9, 16.1R5-S4, 16.1R6-S4, 16.1R7; 16.2 versions prior to 16.2R2-S5; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S6, 17.2R2-S4, 17.2R3; 17.2X75 versions prior to 17.2X75-D110, 17.2X75-D91; 17.3 versions prior to 17.3R1-S4, 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R1-S3, 17.4R2; 18.2X75 versions prior to 18.2X75-D5.

An authentication bypass vulnerability in the initial boot sequence of Juniper Networks Junos OS on vSRX Series may allow an attacker to gain full control of the system without authentication when the system is initially booted up. Affected releases are Juniper Networks Junos OS: 15.1X49 versions prior to 15.1X49-D30 on vSRX.

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. No other Juniper Networks products or platforms are affected by this issue.

Juniper Junos OS before 12.1X46-D50 on SRX Series devices reverts to "safe mode" authentication and allows root CLI logins without a password after a failed upgrade to 12.1X46, which might allow local users to gain privileges by leveraging use of the "request system software" command with the "partition" option.

An Improper Authorization vulnerability in the 'sysmanctl' shell command of Juniper Networks Junos OS Evolved allows a local, authenticated attacker to execute administrative commands that could impact the integrity of the system or system availability. Administrative functions such as daemon restarting, routing engine (RE) switchover, and node shutdown can all be performed through exploitation of the 'sysmanctl' command. Access to the 'sysmanctl' command is only available from the Junos shell. Neither direct nor indirect access to 'sysmanctl' is available from the Junos CLI. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S5-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R2-EVO; 21.4 versions prior to 21.4R1-S2-EVO, 21.4R2-EVO.

Affected releases are Juniper Networks Junos Space all versions prior to 17.1R1.

The network enabled distribution of Kura before 2.1.0 takes control over the device's firewall setup but does not allow IPv6 firewall rules to be configured. Still the Equinox console port 5002 is left open, allowing to log into Kura without any user credentials over unencrypted telnet and executing commands using the Equinox "exec" command. As the process is running as "root" full control over the device can be acquired. IPv6 is also left in auto-configuration mode, accepting router advertisements automatically and assigns a MAC address based IPv6 address.
