CVE-2023-28972 – Junos OS: NFX Series: 'set system ports console insecure' allows root password recovery
https://notcve.org/view.php?id=CVE-2023-28972
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. • https://supportportal.juniper.net/JSA70596 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVE-2023-28974 – Junos OS: MX Series: In a BBE scenario upon receipt of specific malformed packets from subscribers the process bbe-smgd will crash
https://notcve.org/view.php?id=CVE-2023-28974
An Improper Check for Unusual or Exceptional Conditions vulnerability in the bbe-smgd of Juniper Networks Junos OS allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). In a Broadband Edge / Subscriber Management scenario on MX Series when a specifically malformed ICMP packet addressed to the device is received from a subscriber the bbe-smgd will crash, affecting the subscriber sessions that are connecting, updating, or terminating. Continued receipt of such packets will lead to a sustained DoS condition. When this issue happens the below log can be seen if the traceoptions for the processes smg-service are enabled: BBE_TRACE(TRACE_LEVEL_INFO, "%s: Dropped unsupported ICMP PKT ... This issue affects Juniper Networks Junos OS on MX Series: All versions prior to 19.4R3-S11; 20.2 versions prior to 20.2R3-S7; 20.3 versions prior to 20.3R3-S6; 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 22.1R2-S2, 22.1R3; 22.2 versions prior to 22.2R2; 22.3 versions prior to 22.3R1-S2, 22.3R2. • https://supportportal.juniper.net/JSA70599 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVE-2023-28976 – Junos OS: MX Series: If a specific traffic rate goes above the DDoS threshold it will lead to an FPC crash
https://notcve.org/view.php?id=CVE-2023-28976
An Improper Check for Unusual or Exceptional Conditions vulnerability in the packet forwarding engine (pfe) of Juniper Networks Junos OS on MX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). If specific traffic is received on MX Series and its rate exceeds the respective DDoS protection limit the ingress PFE will crash and restart. Continued receipt of this traffic will create a sustained DoS condition. This issue affects Juniper Networks Junos OS on MX Series: All versions prior to 19.1R3-S10; 19.2 versions prior to 19.2R3-S7; 19.3 versions prior to 19.3R3-S8; 19.4 versions prior to 19.4R3-S11; 20.2 versions prior to 20.2R3-S5; 20.4 versions prior to 20.4R3-S6; 21.1 versions prior to 21.1R3-S5; 21.2 versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2. • https://supportportal.juniper.net/JSA70601 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVE-2023-28980 – Junos OS and Junos OS Evolved: In a BGP rib sharding scenario an rpd crash will happen shortly after a specific CLI command is issued
https://notcve.org/view.php?id=CVE-2023-28980
A Use After Free vulnerability in the routing protocol daemon of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause Denial of Service (DoS). In a rib sharding scenario the rpd process will crash shortly after specific CLI command is issued. This issue is more likely to occur in a scenario with high route scale (>1M routes). This issue affects: Juniper Networks Junos OS * 20.2 version 20.2R3-S5 and later versions prior to 20.2R3-S6; * 20.3 version 20.3R3-S2 and later versions prior to 20.3R3-S5; * 20.4 version 20.4R3-S1 and later versions prior to 20.4R3-S4 * 21.1 version 21.1R3 and later versions prior to 21.1R3-S3; * 21.2 version 21.2R1-S2, 21.2R2-S1 and later versions prior to 21.2R3-S2; * 21.3 version 21.3R2 and later versions prior to 21.3R3; * 21.4 versions prior to 21.4R2-S1, 21.4R3; * 22.1 versions prior to 22.1R2.
