CVE-2024-39544
Junos OS Evolved: Low privileged local user able to view NETCONF traceoptions files
An Incorrect Default Permissions vulnerability in the command line interface (CLI) of Juniper Networks Junos OS Evolved allows a low privileged local attacker to view NETCONF traceoptions files, representing an exposure of sensitive information.
On all Junos OS Evolved platforms, when NETCONF traceoptions are configured, NETCONF traceoptions files get created with an incorrect group permission, which allows
a low-privileged user can access sensitive information compromising the confidentiality of the system.
