CVE-2017-18378
In NETGEAR ReadyNAS Surveillance before 1.4.3-17 x86 and before 1.1.4-7 ARM, $_GET['uploaddir'] is not escaped and is passed to system() through $tmp_upload_dir, leading to upgrade_handle.php?cmd=writeuploaddir remote command execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
