CVSS: 6.5EPSS: 0%CPEs: 12EXPL: 0CVE-2022-22166 – Junos OS: An rpd core will occur if BGP update tracing is configured and an update containing a malformed BGP SR-TE policy tunnel attribute is received
https://notcve.org/view.php?id=CVE-2022-22166
An Improper Validation of Specified Quantity in Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause an rdp crash and thereby a Denial of Service (DoS). If a BGP update message is received over an established BGP session where a BGP SR-TE policy tunnel attribute is malformed and BGP update tracing flag is enabled, the rpd will core. This issue can happen with any BGP session as long as the previous conditions are met. This issue can not propagate as the crash occurs as soon as the malformed update is received. This issue affects Juniper Networks Junos OS: 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R2-S2, 21.1R3. • https://kb.juniper.net/JSA11274 • CWE-1284: Improper Validation of Specified Quantity in Input •
CVSS: 6.5EPSS: 0%CPEs: 11EXPL: 0CVE-2022-22164 – Junos OS Evolved: Telnet service may be enabled when it is expected to be disabled.
https://notcve.org/view.php?id=CVE-2022-22164
An Improper Initialization vulnerability in Juniper Networks Junos OS Evolved may cause a commit operation for disabling the telnet service to not take effect as expected, resulting in the telnet service staying enabled. When it is not intended to be operating on the device, an administrator can issue the following command to verify whether telnet is operating in the background: user@device > show system connections | grep :23 tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN 20879/xinetd This issue affects: Juniper Networks Junos OS Evolved All versions prior to 20.4R2-S2-EVO; 21.1 version 21.1R1-EVO and later versions; 21.2 versions prior to 21.2R2-EVO. Una vulnerabilidad de inicialización inapropiada en Juniper Networks Junos OS Evolved puede causar que una operación de confirmación para deshabilitar el servicio telnet no tenga el efecto esperado, lo que hace que el servicio telnet siga habilitado. Cuando no está previsto que funcione en el dispositivo, un administrador puede emitir el siguiente comando para verificar si telnet está funcionando en segundo plano: user@device ) show system connections | grep :23 tcp 0 0.0.0.0:23 0.0.0.0:* LISTEN 20879/xinetd Este problema afecta: Juniper Networks Junos OS Evolved Todas las versiones anteriores a 20.4R2-S2-EVO; 21.1 versión 21.1R1-EVO y versiones posteriores; versiones 21.2 anteriores a 21.2R2-EVO • https://kb.juniper.net/JSA11272 • CWE-665: Improper Initialization •
CVSS: 7.4EPSS: 0%CPEs: 173EXPL: 0CVE-2022-22163 – Junos OS: jdhcpd crashes upon receipt of a specific DHCPv6 packet
https://notcve.org/view.php?id=CVE-2022-22163
An Improper Input Validation vulnerability in the Juniper DHCP daemon (jdhcpd) of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a crash of jdhcpd and thereby a Denial of Service (DoS). If a device is configured as DHCPv6 local server and persistent storage is enabled, jdhcpd will crash when receiving a specific DHCPv6 message. This issue affects: Juniper Networks Junos OS All versions prior to 15.1R7-S11; 18.4 versions prior to 18.4R3-S9; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S3; 19.4 versions prior to 19.4R3-S5; 20.1 versions prior to 20.1R3-S1; 20.2 versions prior to 20.2R3-S2; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2; 21.2 versions prior to 21.2R2. Una vulnerabilidad de comprobación de entrada inapropiada en el demonio DHCP de Juniper (jdhcpd) del Sistema Operativo Junos de Juniper Networks permite a un atacante adyacente no autenticado causar un bloqueo de jdhcpd y, por tanto, una denegación de servicio (DoS). Si un dispositivo está configurado como servidor local DHCPv6 y el almacenamiento persistente está habilitado, jdhcpd será bloqueado cuando reciba un mensaje DHCPv6 específico. • https://kb.juniper.net/JSA11271 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2022-22162
A Generation of Error Message Containing Sensitive Information vulnerability in the CLI of Juniper Networks Junos OS allows a locally authenticated attacker with low privileges to elevate these to the level of any other user logged in via J-Web at this time, potential leading to a full compromise of the device. This issue affects Juniper Networks Junos OS: All versions prior to 15.1R7-S11; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2. Una vulnerabilidad de generación de mensajes de error que contienen información confidencial en la CLI de Juniper Networks Junos OS permite a un atacante autenticado localmente con bajos privilegios elevarlos al nivel de cualquier otro usuario conectado por medio de J-Web en ese momento, lo que podría conllevar a un compromiso total del dispositivo. Este problema afecta a Juniper Networks Junos OS: Todas las versiones anteriores a 15.1R7-S11; las versiones 18.3 anteriores a 18.3R3-S6; las versiones 18.4 anteriores a 18.4R2-S9, 18.4R3-S10; las versiones 19.1 anteriores a 19.1R2-S3, 19.1R3-S7; las versiones 19.2 anteriores a 19.2R1-S8, 19.2R3-S4; las versiones 19.3 anteriores a 19.3R3-S4; las versiones 19. 4 versiones anteriores a 19.4R3-S6; 20.1 versiones anteriores a 20.1R3-S2; versiones 20.2 anteriores a 20.2R3-S3; versiones 20.3 anteriores a 20.3R3-S1; versiones 20.4 anteriores a 20.4R3-S1; versiones 21.1 anteriores a 21.1R2-S1, 21.1R3; versiones 21.2 anteriores a 21.2R1-S1, 21.2R2 • https://kb.juniper.net/JSA11270 • CWE-209: Generation of Error Message Containing Sensitive Information •
CVSS: 7.5EPSS: 0%CPEs: 144EXPL: 0CVE-2022-22161 – Junos OS: MX104 might become unresponsive if the out-of-band management port receives a flood of traffic
https://notcve.org/view.php?id=CVE-2022-22161
An Uncontrolled Resource Consumption vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated network based attacker to cause 100% CPU load and the device to become unresponsive by sending a flood of traffic to the out-of-band management ethernet port. Continued receipted of a flood will create a sustained Denial of Service (DoS) condition. Once the flood subsides the system will recover by itself. An indication that the system is affected by this issue would be that an irq handled by the fman process is shown to be using a high percentage of CPU cycles like in the following example output: user@host> show system processes extensive ...
