CVSS: 6.8EPSS: 0%CPEs: 152EXPL: 0CVE-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') •
CVSS: 7.4EPSS: 0%CPEs: 122EXPL: 0CVE-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 •
CVSS: 5.3EPSS: 0%CPEs: 112EXPL: 0CVE-2023-28984 – Junos OS: QFX Series: The PFE may crash when a lot of MAC addresses are being learned and aged
https://notcve.org/view.php?id=CVE-2023-28984
A Use After Free vulnerability in the Layer 2 Address Learning Manager (l2alm) of Juniper Networks Junos OS on QFX Series allows an adjacent attacker to cause the Packet Forwarding Engine to crash and restart, leading to a Denial of Service (DoS). The PFE may crash when a lot of MAC learning and aging happens, but due to a Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) that is outside the attackers direct control. This issue affects: Juniper Networks Junos OS versions prior to 19.4R3-S10 on QFX Series; 20.2 versions prior to 20.2R3-S7 on QFX Series; 20.3 versions prior to 20.3R3-S6 on QFX Series; 20.4 versions prior to 20.4R3-S5 on QFX Series; 21.1 versions prior to 21.1R3-S4 on QFX Series; 21.2 versions prior to 21.2R3-S3 on QFX Series; 21.3 versions prior to 21.3R3-S3 on QFX Series; 21.4 versions prior to 21.4R3 on QFX Series; 22.1 versions prior to 22.1R3 on QFX Series; 22.2 versions prior to 22.2R2 on QFX Series. • https://supportportal.juniper.net/JSA70610 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 4.6EPSS: 0%CPEs: 114EXPL: 0CVE-2023-28975 – Junos OS: The kernel will crash when certain USB devices are inserted
https://notcve.org/view.php?id=CVE-2023-28975
An Unexpected Status Code or Return Value vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated attacker with physical access to the device to cause a Denial of Service (DoS). When certain USB devices are connected to a USB port of the routing-engine (RE), the kernel will crash leading to a reboot of the device. The device will continue to crash as long as the USB device is connected. This issue affects Juniper Networks Junos OS: All versions prior to 19.4R3-S10; 20.2 versions prior to 20.2R3-S7; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 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, 22.2R3; 22.3 versions prior to 22.3R1-S1, 22.3R2; 22.4 versions prior to 22.4R2. • https://supportportal.juniper.net/JSA70600 • CWE-394: Unexpected Status Code or Return Value CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 7.5EPSS: 0%CPEs: 63EXPL: 0CVE-2023-22408 – Junos OS: SRX 5000 Series: Upon processing of a specific SIP packet an FPC can crash
https://notcve.org/view.php?id=CVE-2023-22408
An Improper Validation of Array Index vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX 5000 Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an attacker sends an SIP packets with a malformed SDP field then the SIP ALG can not process it which will lead to an FPC crash and restart. Continued receipt of these specific packets will lead to a sustained Denial of Service. This issue can only occur when both below mentioned conditions are fulfilled: 1. Call distribution needs to be enabled: [security alg sip enable-call-distribution] 2. • https://kb.juniper.net/JSA70204 • CWE-129: Improper Validation of Array Index •
