CVE-2023-50272 is a high-severity security vulnerability affecting Hewlett Packard Enterprise's Integrated Lights-Out management interfaces, specifically iLO 5 versions from 2.63 up to but not including 3.00, and iLO 6 versions from 1.05 up to but not including 1.55. The vulnerability allows a remote attacker to bypass authentication mechanisms, potentially gaining unauthorized access to the management interface without valid credentials. The vulnerability is classified under CWE-288 (Authentication Bypass Using an Alternate Path or Channel), indicating that the flaw allows attackers to circumvent normal authentication controls by exploiting an alternate access path or logic flaw. The CVSS v3.1 base score is 7.5, reflecting a high severity with the vector AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:H/A:N. This means the attack can be performed remotely over the network without privileges or user interaction, but requires high attack complexity. The impact includes low confidentiality loss, high integrity loss, and no availability impact, with scope changed, indicating that the vulnerability affects components beyond the initially vulnerable system. Although no known exploits are currently reported in the wild, the potential for unauthorized administrative access to iLO interfaces poses significant risk. The iLO management interfaces are critical for remote server management, including power control, firmware updates, and hardware monitoring, making them attractive targets for attackers seeking to compromise enterprise infrastructure.

For European organizations, this vulnerability presents a significant risk to data center and server infrastructure security. Unauthorized access to iLO interfaces can allow attackers to manipulate server hardware settings, deploy malicious firmware, or disrupt operations by altering configurations. This could lead to integrity breaches of critical systems, unauthorized data access, or persistent footholds within enterprise environments. Given the widespread use of HPE servers in European enterprises, government agencies, and cloud providers, exploitation could impact confidentiality and integrity of sensitive data and critical services. The vulnerability's remote exploitability without authentication increases the risk of targeted attacks or automated scanning campaigns. Additionally, compromised iLO interfaces could be leveraged to bypass network security controls, facilitating lateral movement or data exfiltration. The lack of known exploits currently provides a window for proactive mitigation, but the high severity score underscores the urgency for European organizations to address this vulnerability promptly to avoid potential operational disruptions and reputational damage.

European organizations should immediately inventory all HPE servers running iLO 5 and iLO 6 firmware versions within the vulnerable ranges. They should prioritize upgrading iLO firmware to versions 3.00 or later for iLO 5 and 1.55 or later for iLO 6 as soon as official patches become available from HPE. Until patches are applied, organizations should restrict network access to iLO interfaces by implementing strict firewall rules limiting access to trusted management networks or VPNs. Enabling network segmentation to isolate management interfaces from general user networks can reduce exposure. Organizations should also enforce strong authentication mechanisms, such as multifactor authentication (MFA), if supported by the iLO firmware, and monitor access logs for unusual or unauthorized login attempts. Regular vulnerability scanning and penetration testing targeting management interfaces can help detect exploitation attempts. Additionally, disabling unused management protocols and services on iLO interfaces can reduce the attack surface. Maintaining up-to-date asset inventories and applying security best practices for hardware management interfaces are critical to mitigating risks associated with this vulnerability.
