CVSS: 7.4EPSS: 0%CPEs: 112EXPL: 1CVE-2022-22156 – Junos OS: Certificate validation is skipped when fetching system scripts from a HTTPS URL
https://notcve.org/view.php?id=CVE-2022-22156
An Improper Certificate Validation weakness in the Juniper Networks Junos OS allows an attacker to perform Person-in-the-Middle (PitM) attacks when a system script is fetched from a remote source at a specified HTTPS URL, which may compromise the integrity and confidentiality of the device. The following command can be executed by an administrator via the CLI to refresh a script from a remote location, which is affected from this vulnerability: >request system scripts refresh-from (commit | event | extension-service | op | snmp) file filename url <https-url> This issue affects: Juniper Networks Junos OS All versions prior to 18.4R2-S9, 18.4R3-S9; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S7, 19.2R3-S3; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R3-S7; 20.1 versions prior to 20.1R2-S2, 20.1R3; 20.2 versions prior to 20.2R3; 20.3 versions prior to 20.3R2-S1, 20.3R3; 20.4 versions prior to 20.4R2; 21.1 versions prior to 21.1R1-S1, 21.1R2. Una debilidad de comprobación de certificados inapropiada en el Sistema Operativo Junos de Juniper Networks permite a un atacante llevar a cabo ataques de tipo Person-in-the-Middle (PitM) cuando es obtenida una secuencia de comandos del sistema desde una fuente remota en una URL HTTPS especificada, que puede comprometer la integridad y la confidencialidad del dispositivo. El siguiente comando puede ser ejecutado por un administrador por medio de la CLI para refrescar un script desde una ubicación remota, lo cual está afectado por esta vulnerabilidad: )request system scripts refresh-from (commit | event | extension-service | op | snmp) file filename url (https-url) Este problema afecta a: Juniper Networks Junos OS Todas las versiones anteriores a 18.4R2-S9, 18.4R3-S9; 19.1 versiones anteriores a 19.1R2-S3, 19.1R3-S7; 19.2 versiones anteriores a 19.2R1-S7, 19.2R3-S3; 19.3 versiones anteriores a 19.3R3-S4; 19. 4 versiones anteriores a 19.4R3-S7; 20.1 versiones anteriores a 20.1R2-S2, 20.1R3; 20.2 versiones anteriores a 20.2R3; versiones 20.3 anteriores a 20.3R2-S1, 20.3R3; 20.4 versiones anteriores a 20.4R2; 21.1 versiones anteriores a 21.1R1-S1, 21.1R2 • https://kb.juniper.net/JSA11264 • CWE-295: Improper Certificate Validation CWE-300: Channel Accessible by Non-Endpoint CWE-358: Improperly Implemented Security Check for Standard •
CVSS: 6.5EPSS: 0%CPEs: 81EXPL: 0CVE-2022-22155 – Junos OS: ACX5448: FPC memory leak due to IPv6 neighbor flaps
https://notcve.org/view.php?id=CVE-2022-22155
An Uncontrolled Resource Consumption vulnerability in the handling of IPv6 neighbor state change events in Juniper Networks Junos OS allows an adjacent attacker to cause a memory leak in the Flexible PIC Concentrator (FPC) of an ACX5448 router. The continuous flapping of an IPv6 neighbor with specific timing will cause the FPC to run out of resources, leading to a Denial of Service (DoS) condition. Once the condition occurs, further packet processing will be impacted, creating a sustained Denial of Service (DoS) condition, requiring a manual PFE restart to restore service. The following error messages will be seen after the FPC resources have been exhausted: fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 This issue only affects the ACX5448 router.
