CVE-2026-101954

Summary

An unauthenticated attacker can gain root-level access to Juniper devices through the J-Web management interface, allowing complete device takeover without any authentication credentials. This critical vulnerability affects both Junos OS and Junos OS Evolved platforms.

Exploitability

The exploit is highly practical with minimal preconditions - an attacker only needs network access to a device with web management enabled, making it extremely easy to leverage for remote compromise.

Blast radius

This vulnerability could impact thousands of network devices across enterprise and critical infrastructure environments, potentially allowing attackers to gain complete control over network infrastructure with no authentication required.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Disable the J-Web management interface immediately or restrict access to it via firewall rules until a patch is available, as no fixed version has been published in the description.
