CVE-2026-103406：Juniper Session Smart Conductor 允許未授權攻擊者以 root 身份執行任意指令
CVE-2026-103406 - Session Smart Conductor: An unauthenticated attacker causes arbitrary command execution during key management.
Juniper Session Smart Conductor 受 CVE‑2026‑103406 漏洞影響，攻擊者可利用特殊 salt minion ID 在 OS 指令中注入，遠端執行任意指令並以 root 許可權取得控制。
此漏洞可讓遠端攻擊者以 root 身份執行任意指令，提示組織須即時升級 Juniper Session Smart Conductor 以降低高風險攻擊；同時亦提醒需限制遠端存取與使用 vendor 提供的安全補丁，並監控 EPSS 以評估即時威脅。
An Improper Neutralization of Special Elements used in an OS Command vulnerability in the AutomatedProvisioner in Juniper Networks Session Smart Conductor allows a remote attacker to execute arbitrary commands as root via a specially crafted salt minion ID.
