CVSS: 6.5EPSS: 0%CPEs: 359EXPL: 0CVE-2021-0289 – Junos OS: User-defined ARP Policer isn't applied on Aggregated Ethernet (AE) interface until firewall process is restarted
https://notcve.org/view.php?id=CVE-2021-0289
When user-defined ARP Policer is configured and applied on one or more Aggregated Ethernet (AE) interface units, a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability between the Device Control Daemon (DCD) and firewall process (dfwd) daemons of Juniper Networks Junos OS allows an attacker to bypass the user-defined ARP Policer. In this particular case the User ARP policer is replaced with default ARP policer. To review the desired ARP Policers and actual state one can run the command "show interfaces <> extensive" and review the output. See further details below. An example output is: show interfaces extensive | match policer Policer: Input: __default_arp_policer__ <<< incorrect if user ARP Policer was applied on an AE interface and the default ARP Policer is displayed Policer: Input: jtac-arp-ae5.317-inet-arp <<< correct if user ARP Policer was applied on an AE interface For all platforms, except SRX Series: This issue affects Juniper Networks Junos OS: All versions 5.6R1 and all later versions prior to 18.4 versions prior to 18.4R2-S9, 18.4R3-S9 with the exception of 15.1 versions 15.1R7-S10 and later versions; 19.4 versions prior to 19.4R3-S3; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S2; 20.3 version 20.3R1 and later versions; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2; This issue does not affect Juniper Networks Junos OS versions prior to 5.6R1. • https://kb.juniper.net/JSA11191 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 5.9EPSS: 0%CPEs: 83EXPL: 0CVE-2018-0060 – Junos OS: Invalid IP/mask learned from DHCP server might cause device control daemon (dcd) process crash
https://notcve.org/view.php?id=CVE-2018-0060
An improper input validation weakness in the device control daemon process (dcd) of Juniper Networks Junos OS allows an attacker to cause a Denial of Service to the dcd process and interfaces and connected clients when the Junos device is requesting an IP address for itself. Junos devices are not vulnerable to this issue when not configured to use DHCP. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D40 on SRX Series; 12.3X48 versions prior to 12.3X48-D20 on SRX Series; 14.1X53 versions prior to 14.1X53-D40 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; 15.1X53 versions prior to 15.1X53-D68 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D235 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D495 on NFX150, NFX250; 15.1X53 versions prior to 15.1X53-D590 on EX2300/EX3400; 15.1 versions prior to 15.1R7-S2. Una debilidad de validación de entradas incorrecta en el proceso del demonio de control del dispositivo (dcd) de Juniper Networks Junos OS permite que un atacante provoque una denegación de servicio (DoS) en el proceso y las interfaces dcd, así como los clientes conectados, cuando el dispositivo Junos solicita una dirección IP para sí mismo. Los dispositivos Junos no son vulnerables a este problema cuando no están configurados para emplear DHCP. • http://www.securitytracker.com/id/1041858 https://kb.juniper.net/JSA10895 • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 122EXPL: 0CVE-2018-0062 – Junos OS: Denial of Service in J-Web
https://notcve.org/view.php?id=CVE-2018-0062
A Denial of Service vulnerability in J-Web service may allow a remote unauthenticated user to cause Denial of Service which may prevent other users to authenticate or to perform J-Web operations. 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-D60 on SRX Series; 15.1 versions prior to 15.1R7; 15.1F6; 15.1X49 versions prior to 15.1X49-D120 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-D234 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D470, 15.1X53-D495 on NFX Series; 16.1 versions prior to 16.1R6; 16.2 versions prior to 16.2R2-S6, 16.2R3; 17.1 versions prior to 17.1R2-S6, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R2. No other Juniper Networks products or platforms are affected by this issue. Una vulnerabilidad de denegación de servicio (DoS) en el servicio J-Web podría permitir que un usuario remoto no autenticado provoque una denegación de servicio (DoS), lo que evitaría que otros usuarios se autentiquen o realicen operaciones J-Web.

CVSS: 7.2EPSS: 0%CPEs: 204EXPL: 0CVE-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 •
