Description Preview
A security vulnerability has been identified in HPE Integrated Lights-Out 5 (iLO 5) and Integrated Lights-Out 4 (iLO 4) firmware that could allow remote attackers to access sensitive information. This vulnerability enables unauthorized disclosure of the server's serial number and other potentially sensitive information without proper authentication, which could be leveraged in further attacks against the system.
Overview
CVE-2020-7202 affects HPE's Integrated Lights-Out (iLO) management interfaces, specifically versions 4 and 5. iLO is a remote server management technology that provides out-of-band management capabilities for HPE ProLiant servers and BladeSystem servers. The vulnerability allows remote attackers to access sensitive information such as the server's serial number and potentially other configuration details without proper authentication. This information disclosure could be used by attackers to gather intelligence about the target system for use in subsequent attacks or to bypass certain security controls that rely on hardware identifiers.
Remediation
To address this vulnerability, HPE has released firmware updates for affected iLO versions. System administrators should:
- Identify all HPE servers with iLO 4 or iLO 5 management interfaces in their environment.
- Download and install the latest firmware updates from the HPE Support Center.
- For iLO 5, update to firmware version 2.18 or later.
- For iLO 4, update to firmware version 2.77 or later.
- Implement network segmentation to restrict access to iLO interfaces, ensuring they are not directly accessible from untrusted networks.
- Implement strong authentication mechanisms for iLO access.
- Monitor for any unauthorized access attempts to iLO interfaces.
