CVE-2018-1216 is rated critical with a CVSS v3.0 base score of 9.8 and affects Dell Emc Solutions Enabler Virtual Appliance. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

A hard-coded password vulnerability was discovered in vApp Manager which is embedded in Dell EMC Unisphere for VMAX, Dell EMC Solutions Enabler, Dell EMC VASA Virtual Appliances, and Dell EMC VMAX Embedded Management (eManagement): Dell EMC Unisphere for VMAX Virtual Appliance versions prior to 8.4.0.18, Dell EMC Solutions Enabler Virtual Appliance versions prior to 8.4.0.21, Dell EMC VASA Virtual Appliance versions prior to 8.4.0.514, and Dell EMC VMAX Embedded Management (eManagement) versions prior to and including 1.4 (Enginuity Release 5977.1125.1125 and earlier). They contain an undocumented default account (smc) with a hard-coded password that may be used with certain web servlets. A remote attacker with the knowledge of the hard-coded password and the message format may use vulnerable servlets to gain unauthorized access to the system. Note: This account cannot be used to log in via the web user interface.
