FKIE_CVE-2019-5538

Vulnerability from fkie_nvd - Published: 2019-10-28 16:15 - Updated: 2026-06-17 02:37
Severity
5.9 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
Sensitive information disclosure vulnerability resulting from a lack of certificate validation during the File-Based Backup and Restore operations of VMware vCenter Server Appliance (6.7 before 6.7u3a and 6.5 before 6.5u3d) may allow a malicious actor to intercept sensitive data in transit over SCP. A malicious actor with man-in-the-middle positioning between vCenter Server Appliance and a backup target may be able to intercept sensitive data in transit during File-Based Backup and Restore operations.
