Junos OS: UI Discrepancy for Security Feature
CVE-2025-52983 is a high-severity UI discrepancy for security feature vulnerability in Junos OS from Juniper Networks, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions 22.2R3-S7, 22.4R3-S5, 23.2R2-S3 as the first without the flaw, so updating Junos OS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.68% chance of exploitation within 30 days, higher than 53% of scored CVEs.
High severity with no evidence of exploitation so far.

Official description
A UI Discrepancy for Security Feature vulnerability in the UI of Juniper Networks Junos OS on VM Host systems allows a network-based, unauthenticated attacker to access the device. On VM Host Routing Engines (RE), even if the configured public key for root has been removed, remote users which are in possession of the corresponding private key can still log in as root. This issue affects Junos OS: * all versions before 22.2R3-S7, * 22.4 versions before 22.4R3-S5, * 23.2 versions before 23.2R2-S3, * 23.4 versions before 23.4R2-S3, * 24.2 versions before 24.2R1-S2, 24.2R2.
