ID de Prueba:1.3.6.1.4.1.25623.1.0.106133
Categoría:JunOS Local Security Checks
Título:Junos SRX Series: Possible Unauthenticated Root Login Vulnerability
Resumen:Junos OS on SRX series is prone to a possible unauthenticated;root login vulnerability
Descripción:Summary:
Junos OS on SRX series is prone to a possible unauthenticated
root login vulnerability

Vulnerability Insight:
Using the 'request system software' command with the 'partition' option
on an SRX Series device upgrading to Junos OS 12.1X46 can leave the system in a state where root CLI login
is allowed without a password due to the system reverting to a 'safe mode' authentication triggered by the
failed upgrade. Additionally, valid authentication credentials fail to work due to the same issue. Only root
with no password will work.

This issue only affects SRX Series devices upgraded to Junos OS 12.1X46 releases. No other platform or version
of Junos OS is affected by this vulnerability, and no other Juniper Networks products or platforms are affected
by this issue.

Vulnerability Impact:
A local attacker may gain root access.

Affected Software/OS:
Junos OS 12.1X46 on SRX Series

Solution:
New builds of Junos OS software are available from Juniper.
As a workaround avoid using the 'partition' option when upgrading an SRX Series device to Junos OS 12.1X46
prior to 12.1X46-D50.
