CVE-2023-32463Network attack vector

Service degradation via undisclosed upgrade input validation

Published Jun 23, 2023 · Updated Nov 8, 2024

Denial of service in Dell VxRail Appliance before 8.0.100 allows remote attackers to degrade performance through upgrade functionality. Dell identifies improper input validation but has not disclosed the affected upgrade component, input, or failed validation operation. The description states that unauthenticated remote access is sufficient, while Dell's CVSS vector requires a local, highly privileged attacker; exploitation degrades performance and causes system malfunction.
