Vulnerability description
DayBreach CVE AI Research
CVE-2026-33793 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
