An Improper Check or Handling of Exceptional Conditions vulnerability in packet processing on the network interfaces of Juniper Networks Junos OS on JRR200 route reflector appliances allows an adjacent, network-based attacker sending a specific packet to the device to cause a kernel crash, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue can only be triggered by an attacker on the local broadcast domain. Packets routed to the device are unable to trigger this crash. This issue affects Juniper Networks Junos OS on JRR200: All versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3-S4; 21.4 versions prior to 21.4R3-S3; 22.1 versions prior to 22.1R3-S1; 22.2 versions prior to 22.2R2-S2, 22.2R3; 22.3 versions prior to 22.3R1-S2, 22.3R2; 22.4 versions prior to 22.4R1-S1, 22.4R2.

An Improper Link Resolution Before File Access vulnerability in console port access of Juniper Networks Junos OS on NFX Series allows an attacker to bypass console access controls. When "set system ports console insecure" is enabled, root login is disallowed for Junos OS as expected. However, the root password can be changed using "set system root-authentication plain-text-password" on NFX Series systems, leading to a possible administrative bypass with physical access to the console. Password recovery, changing the root password from a console, should not have been allowed from an insecure console. This is similar to the vulnerability described in CVE-2019-0035 but affects different platforms and in turn requires a different fix. This issue affects Juniper Networks Junos OS on NFX Series: 19.2 versions prior to 19.2R3-S7; 19.3 versions prior to 19.3R3-S8; 19.4 versions prior to 19.4R3-S12; 20.2 versions prior to 20.2R3-S8; 20.4 versions prior to 20.4R3-S7; 21.1 versions prior to 21.1R3-S5; 21.2 versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3-S2; 22.1 versions prior to 22.1R3-S1; 22.2 versions prior to 22.2R2-S1, 22.2R3; 22.3 versions prior to 22.3R1-S2, 22.3R2.

An Improper Check or Handling of Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS on QFX10002 allows an unauthenticated, adjacent attacker on the local broadcast domain sending a malformed packet to the device, causing all PFEs other than the inbound PFE to wedge and to eventually restart, resulting in a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue can only be triggered by sending a specific malformed packet to the device. Transit traffic does not trigger this issue. An indication of this issue occurring can be seen through the following log messages: fpc0 expr_hostbound_packet_handler: Receive pe 73? fpc0 Cmerror Op Set: PE Chip: PE0[0]: PGQ:misc_intr: 0x00000020: Enqueue of a packet with out-of-range VOQ in 192K-VOQ mode (URI: /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL) The logs list below can also be observed when this issue occurs fpc0 Error: /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL (0x210107), scope: pfe, category: functional, severity: major, module: PE Chip, type: Description for PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL fpc0 Performing action cmalarm for error /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL (0x210107) in module: PE Chip with scope: pfe category: functional level: major fpc0 Error: /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE (0x21011a), scope: pfe, category: functional, severity: fatal, module: PE Chip, type: Description for PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE fpc0 Performing action cmalarm for error /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE (0x21011a) in module: PE Chip with scope: pfe category: functional level: fatal fpc0 Performing action disable-pfe for error /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE (0x21011a) in module: PE Chip with scope: pfe category: functional level: fatal This issue affects Juniper Networks Junos OS on QFX10002: All versions prior to 19.1R3-S10; 19.4 versions prior to 19.4R3-S11; 20.2 versions prior to 20.2R3-S7; 20.4 versions prior to 20.4R3-S6; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3-S2; 22.1 versions prior to 22.1R3-S1; 22.2 versions prior to 22.2R2-S1, 22.2R3; 22.3 versions prior to 22.3R1-S2, 22.3R2.
