Summary
Airleader Master versions 6.381 and earlier contain a vulnerability that could allow an attacker to obtain remote code execution. The vulnerability is related to improper input validation (CWE-434). Exploitation requires only network access with no authentication required.
What this means
What could happen
An attacker could execute arbitrary code on Airleader Master, potentially allowing them to modify setpoints, disable monitoring, or disrupt HVAC control and facility operations.
Who's at risk
Facility managers and HVAC technicians operating Airleader Master building automation systems, particularly in commercial buildings, data centers, hospitals, and other facilities where uninterrupted environmental control is critical.
How it could be exploited
An attacker on the network could send a specially crafted request to Airleader Master over the network (port/protocol unspecified in advisory) to trigger the vulnerability and execute commands with the same privileges as the Airleader Master process.
