Impacted is confidentiality, integrity, and availability. CVE summarizes:

Data Center Expert, versions 7.5.0 and earlier, allows for the upload of a zip file from its user interface to the server. A carefully crafted, malicious file could be mistakenly uploaded by an authenticated user via this feature which could contain path traversal file names.

This is leveraging the more commonly known ZipSlip vulnerability within Java code.
