What it is

From the CVE record

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.
