CVE-2018-11141
The 'IMAGES_JSON' and 'attachments_to_remove[]' parameters of the '/adminui/advisory.php' script in the Quest KACE System Management Virtual Appliance 8.0.318 can be abused to write and delete files respectively via Directory Traversal.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
