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:
Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
This issue was found during internal product security testing or research.
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 MIST managed WAN Assurance routers connected to the Mist Cloud.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.
