Mitsubishi (CVE-2019-14931)

critical Tenable OT Security Plugin ID 500598

Synopsis

The remote OT asset is affected by a vulnerability.

Description

An issue was discovered on Mitsubishi Electric Europe B.V. ME-RTU devices through 2.02 and INEA ME-RTU devices through 3.0. An unauthenticated remote OS Command Injection vulnerability allows an attacker to execute arbitrary commands on the RTU due to the passing of unsafe user supplied data to the RTU's system shell. Functionality in mobile.php provides users with the ability to ping sites or IP addresses via Mobile Connection Test. When the Mobile Connection Test is submitted, action.php is called to execute the test. An attacker can use a shell command separator (;) in the host variable to execute operating system commands upon submitting the test data.
