Overview

CVE-2018-0052 is a high-severity vulnerability. It was published on October 10, 2018 and has a CVSS 3.0 base score of 7.2 (HIGH).

This vulnerability has a CVSS 3.0 base score of 7.2, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

If RSH service is enabled on Junos OS and if the PAM authentication is disabled, a remote unauthenticated attacker can obtain root access to the device. RSH service is disabled by default on Junos. There is no documented CLI command to enable this service. However, an undocumented CLI command allows a privileged Junos user to enable RSH service and disable PAM, and hence expose the system to unauthenticated root access. When RSH is enabled, the device is listing to RSH connections on port 514. This issue is not exploitable on platforms where Junos release is based on FreeBSD 10+. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D77 on SRX Series; 12.3 versions prior to 12.3R12-S10; 12.3X48 versions prior to 12.3X48-D75 on SRX Series; 14.1X53 versions prior to 14.1X53-D47 on QFX/EX Series; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D131, 15.1X49-D140 on SRX Series; 15.1X53 versions prior to 15.1X53-D59 on EX23
