CVSS: 7.8EPSS: 0%CPEs: 24EXPL: 0CVE-2023-28966 – Junos OS Evolved: Local low-privileged user with shell access can execute CLI commands as root
https://notcve.org/view.php?id=CVE-2023-28966
An Incorrect Default Permissions vulnerability in Juniper Networks Junos OS Evolved allows a low-privileged local attacker with shell access to modify existing files or execute commands as root. The issue is caused by improper file and directory permissions on certain system files, allowing an attacker with access to these files and folders to inject CLI commands as root. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S5-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R2-EVO. • https://supportportal.juniper.net/JSA70590 • CWE-276: Incorrect Default Permissions •
CVSS: 7.1EPSS: 0%CPEs: 35EXPL: 0CVE-2023-28973 – Junos OS Evolved: The 'sysmanctl' shell command allows a local user to gain access to some administrative actions
https://notcve.org/view.php?id=CVE-2023-28973
An Improper Authorization vulnerability in the 'sysmanctl' shell command of Juniper Networks Junos OS Evolved allows a local, authenticated attacker to execute administrative commands that could impact the integrity of the system or system availability. Administrative functions such as daemon restarting, routing engine (RE) switchover, and node shutdown can all be performed through exploitation of the 'sysmanctl' command. Access to the 'sysmanctl' command is only available from the Junos shell. Neither direct nor indirect access to 'sysmanctl' is available from the Junos CLI. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S5-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R2-EVO; 21.4 versions prior to 21.4R1-S2-EVO, 21.4R2-EVO. • https://supportportal.juniper.net/JSA70597 • CWE-285: Improper Authorization CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2023-28978
An Insecure Default Initialization of Resource vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network based attacker to read certain confidential information. In the default configuration it is possible to read confidential information about locally configured (administrative) users of the affected system. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S7-EVO on pending commit???; 21.1-EVO versions prior to 21.1R3-S4-EVO on awaiting build; 21.4-EVO versions prior to 21.4R3-S1-EVO; 22.2-EVO versions prior to 22.2R3-EVO; 21.2-EVO versions prior to 21.2R3-S5-EVO on pending commit???; 21.3-EVO version 21.3R1-EVO and later versions; 22.1-EVO version 22.1R1-EVO and later versions; 22.2-EVO versions prior to 22.2R2-S1-EVO. • https://supportportal.juniper.net/JSA70603 • CWE-1188: Initialization of a Resource with an Insecure Default •
CVSS: 7.5EPSS: 0%CPEs: 176EXPL: 0CVE-2023-28964 – Junos OS and Junos OS Evolved: Malformed BGP flowspec update causes RPD crash
https://notcve.org/view.php?id=CVE-2023-28964
An Improper Handling of Length Parameter Inconsistency vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network based, unauthenticated attacker to cause an RPD crash leading to a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Upon receipt of a malformed BGP flowspec update, RPD will crash resulting in a Denial of Service. This issue affects Juniper Networks Junos OS: All versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S6; 18.3 versions prior to 18.3R3-S4; 18.4 versions prior to 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R3-S1; 19.3 versions prior to 19.3R3-S1; 19.4 versions prior to 19.4R3; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2; 20.3 versions prior to 20.3R1-S1, 20.3R2; Juniper Networks Junos OS Evolved: All versions prior to 20.1R3-EVO; 20.2 versions prior to 20.2R2-EVO; 20.3 versions prior to 20.3R2-EVO; • https://supportportal.juniper.net/JSA70588 • CWE-130: Improper Handling of Length Parameter Inconsistency •
CVSS: 6.1EPSS: 0%CPEs: 31EXPL: 0CVE-2023-22397 – Junos OS Evolved: PTX10003: An attacker sending specific genuine packets will cause a memory leak in the PFE leading to a Denial of Service
https://notcve.org/view.php?id=CVE-2023-22397
An Allocation of Resources Without Limits or Throttling weakness in the memory management of the Packet Forwarding Engine (PFE) on Juniper Networks Junos OS Evolved PTX10003 Series devices allows an adjacently located attacker who has established certain preconditions and knowledge of the environment to send certain specific genuine packets to begin a Time-of-check Time-of-use (TOCTOU) Race Condition attack which will cause a memory leak to begin. Once this condition begins, and as long as the attacker is able to sustain the offending traffic, a Distributed Denial of Service (DDoS) event occurs. As a DDoS event, the offending packets sent by the attacker will continue to flow from one device to another as long as they are received and processed by any devices, ultimately causing a cascading outage to any vulnerable devices. Devices not vulnerable to the memory leak will process and forward the offending packet(s) to neighboring devices. Due to internal anti-flood security controls and mechanisms reaching their maximum limit of response in the worst-case scenario, all affected Junos OS Evolved devices will reboot in as little as 1.5 days. • https://kb.juniper.net/JSA70193 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-770: Allocation of Resources Without Limits or Throttling •
