CVE-2022-28632 : Vulnerability Insights and Analysis

A potential arbitrary code execution and denial of service (DoS) vulnerability has been identified in HPE Integrated Lights-Out 5 (iLO 5) firmware version(s) prior to 2.71. This could allow an unprivileged user to execute arbitrary code in an isolated process, leading to a loss of confidentiality, integrity, and availability within that process. Additionally, exploitation of the DoS vulnerability in an isolated process could result in a complete loss of availability within that process. HPE has released a firmware update to address this security issue.

Understanding CVE-2022-28632

This section provides insights into the nature and implications of the CVE-2022-28632 vulnerability.

What is CVE-2022-28632?
