CVE-2020-1631

Juniper Junos OS path traversal flaw in J-Web and related services allows unauthenticated remote code execution.

An unauthenticated attacker can exploit this path traversal vulnerability in Juniper Junos OS to execute arbitrary code remotely via J-Web, Web Authentication, DVPN, and ZTP services. This is a critical failure for DIB organizations relying on Juniper networking gear, as it directly enables remote code execution without authentication, violating core security controls and risking network compromise. Organizations must immediately patch Junos OS and restrict access to these web services until a fix is applied.

Shame score — A path traversal flaw enabling unauthenticated remote code execution in core networking OS is a severe, avoidable failure that directly compromises network integrity and violates fundamental security principles.
