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
The following software releases have been updated to resolve this specific issue: Junos OS: 21.2R3-S7, 21.4R3-S5, 22.1R3-S5, 22.2R3-S3, 22.3R3-S2, 22.4R3, 23.2R1-S2, 23.4R1 and all subsequent releases. Junos OS Evolved: 21.2R3-S7-EVO, 21.3R3-S5-EVO, 21.4R3-S5-EVO, 22.1R3-S5-EVO, 22.2R3-S3-EVO, 22.3R3-S2-EVO, 22.4R3-EVO, 23.2R1-S2-EVO, 23.4R1-EVO and all subsequent releases.
To reduce the risk of exploitation, enable access control lists (ACLs) and other filtering mechanisms to limit access to the device only from trusted hosts and networks to the NETCONF service.
