CVE-2021-45887
Due to path traversal in private/SchemaSetUpload.do for uploaded ZIP files, an executable script can be uploaded by web application administrators, giving the attacker remote code execution on the underlying server via an imgs/*.jsp URI.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
