This vulnerability arises due to improper handling of untrusted input, which is passed directly to system-level commands without adequate sanitization or validation. Successful exploitation could allow attackers to execute arbitrary commands on the affected system, potentially resulting in unauthorized access, data leakage, or full system compromise. Affected WebUI parameters are \"hd\" and \"pi\".
