Vulnerability from variot

If all 64 digits of the connectivity association name (CKN) key or all 32 digits of the connectivity association key (CAK) key are not configured, all remaining digits will be auto-configured to 0. Hence, Juniper devices configured with short MacSec keys are at risk to an increased likelihood that an attacker will discover the secret passphrases configured for these keys through dictionary-based and brute-force-based attacks using spoofed packets. Affected releases are Juniper Networks Junos OS: 14.1 versions prior to 14.1R10, 14.1R9; 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D100; 15.1X53 versions prior to 15.1X53-D59; 16.1 versions prior to 16.1R3-S8, 16.1R4-S8, 16.1R5; 16.2 versions prior to 16.2R1-S6, 16.2R2; 17.1 versions prior to 17.1R2. Juniper Networks Junos OS Contains vulnerabilities related to certificate and password management.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Juniper Networks Junos OS is a set of network operating system of Juniper Networks (Juniper Networks) dedicated to the company's hardware equipment. The operating system provides a secure programming interface and Junos SDK. There is a trust management issue vulnerability in Juniper Networks Junos OS, which originates from the lack of an effective trust management mechanism in network systems or products. Attackers can use default passwords or hard-coded passwords, hard-coded certificates, etc. to attack affected components. The following releases are affected: Juniper Junos OS Release 14.1, Release 14.1X53, Release 15.1, Release 15.1X49, Release 15.1X53, Release 16.1, Release 16.2, Release 17.1

    "data": "If all 64 digits of the connectivity association name (CKN) key or all 32 digits of the connectivity association key (CAK) key are not configured, all remaining digits will be auto-configured to 0. Hence, Juniper devices configured with short MacSec keys are at risk to an increased likelihood that an attacker will discover the secret passphrases configured for these keys through dictionary-based and brute-force-based attacks using spoofed packets. Affected releases are Juniper Networks Junos OS: 14.1 versions prior to 14.1R10, 14.1R9; 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D100; 15.1X53 versions prior to 15.1X53-D59; 16.1 versions prior to 16.1R3-S8, 16.1R4-S8, 16.1R5; 16.2 versions prior to 16.2R1-S6, 16.2R2; 17.1 versions prior to 17.1R2. Juniper Networks Junos OS Contains vulnerabilities related to certificate and password management.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Juniper Networks Junos OS is a set of network operating system of Juniper Networks (Juniper Networks) dedicated to the company\u0027s hardware equipment. The operating system provides a secure programming interface and Junos SDK. There is a trust management issue vulnerability in Juniper Networks Junos OS, which originates from the lack of an effective trust management mechanism in network systems or products. Attackers can use default passwords or hard-coded passwords, hard-coded certificates, etc. to attack affected components. The following releases are affected: Juniper Junos OS Release 14.1, Release 14.1X53, Release 15.1, Release 15.1X49, Release 15.1X53, Release 16.1, Release 16.2, Release 17.1",
