A UNIX Symbolic Link (Symlink) Following vulnerability in the CLI of Juniper Networks Junos OS allows a local, authenticated attacker with low privileges to escalate their privileges to root which will lead to a complete compromise of the system.

When after a user has performed a specific 'file link ...' CLI operation, another user commits (unrelated configuration changes), the first user can login as root.

This issue affects Junos OS: * all versions before 23.2R2-S7, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S3, * 24.4 versions before 24.4R2-S2, * 25.2 versions before 25.2R2.

This issue does not affect versions 25.4R1 or later.

Ein Angreifer kann mehrere Schwachstellen in Juniper Apstra, Junos OS, Junos OS Evolved und Junos Space ausnutzen, um erweiterte Berechtigungen – sogar Root-Rechte – zu erlangen, beliebigen Code auszuführen – auch mit erweiterten Berechtigungen –, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, Cross-Site-Scripting-Angriffe durchzuführen oder Daten zu manipulieren.
