Technical details
A stored OS command injection vulnerability exists in the parent-control module where user-supplied profile names containing shell metacharacters are not properly sanitized before being processed during automated cloud report generation. The vulnerability requires administrative access and operates on the local network (adjacent attack vector). Successful exploitation allows arbitrary command execution on the device with full compromise of confidentiality, integrity, and availability. The vulnerable code path is triggered asynchronously during the daily cloud report process, making it a time-delayed but reliable exploitation vector.
