CVE-2020-5588Network attack vector

Administrator-only information disclosure via portal path traversal

Published Jun 30, 2020 · Updated Aug 4, 2024

Path traversal in the Cybozu Garoon 5.0.0 through 5.0.1 portal allows remote authenticated users with administrator rights to read data. Cybozu and JVN identify the portal as the affected locus but do not disclose the request parameter or pathname operation that permits traversal. Administrative access is required, and the documented consequence is limited to confidentiality with no reported data modification or service interruption.
