Critical Juniper PTX Flaw Enables Full Router Takeover

🚨 A critical privilege escalation vulnerability in Junos OS Evolved on PTX Series routers (CVE-2026-21902) can allow unauthenticated remote code execution as root by exposing the On-Box Anomaly Detection framework on an externally accessible port. Because the service runs as root and is enabled by default, an attacker with network access could fully compromise affected devices. Juniper released fixes in 25.4R1-S1-EVO, 25.4R2-EVO and 26.2R1-EVO, and recommends applying updates, restricting access with firewall filters or ACLs, or disabling the service using request pfe anomalies disable.
