CVE-2026-33793

8.5 high SSVC exploitation: none Analyzed
NVD · CVE.org

An Execution with Unnecessary Privileges vulnerability in the User Interface (UI) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to gain root privileges, thus compromising the system. When a configuration that allows unsigned Python op scripts is present on the device, a non-root user is able to execute malicious op scripts as a root-equivalent user, leading to privilege escalation. This issue affects Junos OS: * All versions before 22.4R3-S7, * from 23.2 before 23.2R2-S4, * from 23.4 before 23.4R2-S6, * from 24.2 before 24.2R1-S2, 24.2R2, * from 24.4 before 24.4R1-S2, 24.4R2; Junos OS Evolved: * All versions before 22.4R3-S7-EVO, * from 23.2 before 23.2R2-S4-EVO, * from 23.4 before 23.4R2-S6-EVO, * from 24.2 before 24.2R2-EVO, * from 24.4 before 24.4R1-S1-EVO, 24.4R2-EVO.
