​A command injection vulnerability exists in Trane XL824, XL850, XL1050, and Pivot thermostats allowing an attacker to execute arbitrary commands as root using a specially crafted filename. The vulnerability requires physical access to the device via a USB stick.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
