CVE-2020-3945Network attack vector

Sensitive information disclosure via incorrect adapter pairing

Published Feb 19, 2020 · Updated Aug 4, 2024

Information disclosure in VMware Horizon Adapter 6.6.x before 6.6.1 and 6.7.x before 6.7.1 allows remote attackers to obtain sensitive data. The pairing workflow between the adapter and Horizon View incorrectly establishes trust, exposing information that can bypass adapter authentication. Exploitation requires network access to vRealize Operations while the Horizon Adapter is running; no integrity or availability impact is reported.
