An Authentication Bypass Using an Alternate Path or Channel vulnerability in Juniper Networks Session Smart Router may allows a network-based attacker to bypass authentication and take administrative control of the device.

This issue affects Session Smart Router:

from 5.6.7 before 5.6.17,  from 6.0 before 6.0.8 (affected from 6.0.8),

from 6.1 before 6.1.12-lts,  from 6.2 before 6.2.8-lts,  from 6.3 before 6.3.3-r2;

This issue affects Session Smart Conductor:

from 5.6.7 before 5.6.17,  from 6.0 before 6.0.8 (affected from 6.0.8),

from 6.1 before 6.1.12-lts,  from 6.2 before 6.2.8-lts,  from 6.3 before 6.3.3-r2;

This issue affects WAN Assurance Managed Routers:

from 5.6.7 before 5.6.17,  from 6.0 before 6.0.8 (affected from 6.0.8),

from 6.1 before 6.1.12-lts,  from 6.2 before 6.2.8-lts,  from 6.3 before 6.3.3-r2.

Remedy

The following software releases have been updated to resolve this issue: Session Smart Router: SSR-5.6.17, SSR-6.1.12-lts, SSR-6.2.8-lts, SSR-6.3.3-r2 and subsequent releases. It is suggested to upgrade all affected systems to one of these versions of software. In a Conductor-managed deployment, it is sufficient to upgrade only the Conductor nodes and the fix will be applied automatically to all connected routers. As practical, the routers should still be upgraded to a fixed version however they will not be vulnerable once they connect to an upgraded Conductor. Router patching can be confirmed once the router reaches the “running" (on 6.2 and earlier) or “synchronized” (on 6.3+) state on the Conductor".   This vulnerability has been patched automatically on devices that operate with WAN Assurance (where configuration is also managed) connected to the Mist Cloud. As practical, the routers should still be upgraded to a version containing the fix. It is important to note that when the fix is applied automatically on routers managed by a Conductor or on WAN assurance, it will have no impact on data-plane functions of the router. The application of the fix is non-disruptive to production traffic. There may be a momentary downtime (less than 30 seconds) to the web-based management and APIs.

An Authentication Bypass Using an Alternate Path or Channel vulnerability in Juniper Networks Session Smart Router or conductor running with a redundant peer allows a network based attacker to bypass authentication and take full control of the device. Only routers or conductors that are running in high-availability redundant configurations are affected by this vulnerability.

No other Juniper Networks products or platforms are affected by this issue.

This issue affects:

Session Smart Router:

All versions before 5.6.15,  from 6.0 before 6.1.9-lts,  from 6.2 before 6.2.5-sts.

Session Smart Conductor:

All versions before 5.6.15,  from 6.0 before 6.1.9-lts,  from 6.2 before 6.2.5-sts.

WAN Assurance Router:

6.0 versions before 6.1.9-lts,  6.2 versions before 6.2.5-sts.

Remedy

The following software releases have been updated to resolve this issue: Session Smart Router: SSR-5.6.15, SSR-6.1.9-lts, SSR-6.2.5-sts, and subsequent releases. It is suggested to upgrade all affected systems to these versions of software. In a Conductor-managed deployment, it is sufficient to upgrade the Conductor nodes only and the fix will be applied automatically to all connected routers. As practical, the routers should still be upgraded to a fixed version however they will not be vulnerable once they connect to an upgraded Conductor. This vulnerability has been patched automatically on affected devices for WAN Assurance routers connected to the Mist Cloud. For systems that are provisioned in a High-Availability cluster, these should be upgraded to a patched version as soon as practical (SSR-6.1.9 or SSR-6.2.5). It is important to note that the fix is applied automatically on managed routers by a Conductor or on WAN assurance routers has no impact on data-plane functions of the router. The application of the fix is non-disruptive to production traffic. There may be a momentary downtime (less than 30 seconds) to the web-based management and APIs however this will resolve quickly.
