CVSS: 7.8EPSS: 0%CPEs: 183EXPL: 0CVE-2021-0255 – Junos OS: ethtraceroute Local Privilege Escalation vulnerability in SUID binaries
https://notcve.org/view.php?id=CVE-2021-0255
A local privilege escalation vulnerability in ethtraceroute of Juniper Networks Junos OS may allow a locally authenticated user with shell access to escalate privileges and write to the local filesystem as root. ethtraceroute is shipped with setuid permissions enabled and is owned by the root user, allowing local users to run ethtraceroute with root privileges. This issue affects Juniper Networks Junos OS: 15.1X49 versions prior to 15.1X49-D240; 17.3 versions prior to 17.3R3-S11, 17.4 versions prior to 17.4R3-S4; 18.1 versions prior to 18.1R3-S12; 18.2 versions prior to 18.2R3-S7; 18.3 versions prior to 18.3R3-S4; 18.4 versions prior to 18.4R2-S7; 19.1 versions prior to 19.1R1-S6, 19.1R2-S2, 19.1R3-S4; 19.3 versions prior to 19.3R3-S2; 19.4 versions prior to 19.4R3-S1; 20.1 versions prior to 20.1R2, 20.1R3; 20.2 versions prior to 20.2R2-S1, 20.2R3; 20.3 versions prior to 20.3R1-S1. Una vulnerabilidad de escalada de privilegios local en ethtraceroute de Juniper Networks Junos OS, puede permitir a un usuario autenticado localmente con acceso de shell escalar privilegios y escribir en el sistema de archivos local como root. ethtraceroute es enviado con los permisos setuid habilitados y es propiedad del usuario root, permitiendo a usuarios locales locales ejecutar ethtraceroute con privilegios de root. Este problema afecta a Junos de Juniper Networks OS: versiones 15.1X49 anteriores a 15.1X49-D240; Versiones 17.3 anteriores a 17.3R3-S11, versiones 17.4 anteriores a 17.4R3-S4; versiones 18.1 anteriores a 18.1R3-S12; versiones 18.2 anteriores a 18.2R3-S7; versiones 18.3 anteriores a 18.3R3-S4; versiones 18.4 anteriores a 18.4R2-S7; versiones 19.1 anteriores a 19.1R1-S6, 19.1R2-S2, 19.1R3-S4; versiones 19.3 anteriores a 19.3R3-S2; versiones 19.4 anteriores a 19.4R3-S1; versiones 20.1 anteriores a 20.1R2, 20.1R3; versiones 20.2 anteriores a 20.2R2-S1, 20.2R3 • https://kb.juniper.net/JSA11175 • CWE-250: Execution with Unnecessary Privileges CWE-269: Improper Privilege Management •
CVSS: 9.8EPSS: 0%CPEs: 235EXPL: 0CVE-2021-0254 – Junos OS: Remote code execution vulnerability in overlayd service
https://notcve.org/view.php?id=CVE-2021-0254
A buffer size validation vulnerability in the overlayd service of Juniper Networks Junos OS may allow an unauthenticated remote attacker to send specially crafted packets to the device, triggering a partial Denial of Service (DoS) condition, or leading to remote code execution (RCE). Continued receipt and processing of these packets will sustain the partial DoS. The overlayd daemon handles Overlay OAM packets, such as ping and traceroute, sent to the overlay. The service runs as root by default and listens for UDP connections on port 4789. This issue results from improper buffer size validation, which can lead to a buffer overflow. • https://kb.juniper.net/JSA11147 • CWE-131: Incorrect Calculation of Buffer Size CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-0253
NFX Series devices using Juniper Networks Junos OS are susceptible to a local command execution vulnerability thereby allowing an attacker to elevate their privileges via the Junos Device Management Daemon (JDMD) process. This issue affects Juniper Networks Junos OS on NFX Series 17.2 version 17.2R1 and later versions prior to 18.3R3-S4; 18.4 versions prior to 18.4R2-S5, 18.4R3-S5; 19.1 versions prior to 19.1R1-S3; 19.2 version 19.1R2 and later versions prior to 19.2R3; 19.3 versions prior to 19.3R3; 19.4 versions prior to 19.4R2-S2. 19.4 versions 19.4R3 and above. This issue does not affect Juniper Networks Junos OS versions prior to 17.2R1. This issue does not affect the JDMD as used by Junos Node Slicing such as External Servers use in conjunction with Junos Node Slicing and In-Chassis Junos Node Slicing on MX480, MX960, MX2008, MX2010, MX2020. Los dispositivos de la serie NFX que utilizan Juniper Networks Junos OS son susceptibles a una vulnerabilidad de ejecución de comandos locales, permitiendo a un atacante elevar sus privilegios por medio del proceso Junos Device Management Daemon (JDMD). • https://github.com/orangecertcc/security-research/security/advisories/GHSA-vrf9-cjcp-rwcr https://kb.juniper.net/JSA11146 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 8.6EPSS: 0%CPEs: 145EXPL: 0CVE-2021-0251 – Junos OS: MX Series with MS-PIC, MS-SPC3, MS-MIC or MS-MPC: The BRAS Subscriber Services service activation portal is vulnerable to a Denial of Service (DoS) via malformed HTTP packets
https://notcve.org/view.php?id=CVE-2021-0251
A NULL Pointer Dereference vulnerability in the Captive Portal Content Delivery (CPCD) services daemon (cpcd) of Juniper Networks Junos OS on MX Series with MS-PIC, MS-SPC3, MS-MIC or MS-MPC allows an attacker to send malformed HTTP packets to the device thereby causing a Denial of Service (DoS), crashing the Multiservices PIC Management Daemon (mspmand) process thereby denying users the ability to login, while concurrently impacting other mspmand services and traffic through the device. Continued receipt and processing of these malformed packets will create a sustained Denial of Service (DoS) condition. While the Services PIC is restarting, all PIC services will be bypassed until the Services PIC completes its boot process. An attacker sending these malformed HTTP packets to the device who is not part of the Captive Portal experience is not able to exploit this issue. This issue is not applicable to MX RE-based CPCD platforms. • https://kb.juniper.net/JSA11144 • CWE-476: NULL Pointer Dereference •
