CVE-2024-21615

Junos OS and Junos OS Evolved: A low-privileged user can access confidential information

Description

An Incorrect Default Permissions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to access confidential information on the system. On all Junos OS and Junos OS Evolved platforms, when NETCONF traceoptions are configured, and a super-user performs specific actions via NETCONF, then a low-privileged user can access sensitive information compromising the confidentiality of the system. This issue affects: Junos OS: * all versions before 21.2R3-S7,  * from 21.4 before 21.4R3-S5,  * from 22.1 before 22.1R3-S5,  * from 22.2 before 22.2R3-S3,  * from 22.3 before 22.3R3-S2,  * from 22.4 before 22.4R3,  * from 23.2 before 23.2R1-S2. Junos OS Evolved:  * all versions before 21.2R3-S7-EVO,  * from 21.3 before 21.3R3-S5-EVO,  * from 21.4 before 21.4R3-S5-EVO,  * from 22.1 before 22.1R3-S5-EVO,  * from 22.2 before 22.2R3-S3-EVO,  * from 22.3 before 22.3R3-S2-EVO, * from 22.4 before 22.4R3-EVO,  * from 23.2 before 23.2R1-S2.
