Technical details
The vulnerability exists in multiple functions within aaPanel's File Manager component (ExecShell, Zip, UnZip, SetFileAccess) where user-supplied arguments (sfile, dfile, password, access, user) are concatenated unsanitized into shell commands executed via subprocess.Popen with shell=True. An authenticated attacker can break out of single-quoted strings or inject unquoted parameters to execute arbitrary OS commands as root. The exploit requires valid authentication but allows remote code execution.
