A potential security vulnerability has been identified in HPE Integrated Lights-Out 5 (iLO 5) and Integrated Lights-Out 6 (iLO 6). This vulnerability allows remote exploitation that could lead to authentication bypass, posing significant risks to affected systems.
The severity of this vulnerability is classified as high, with a CVSS score of 7.5. This indicates a serious risk to organizations that utilize these systems, as attackers could potentially exploit the vulnerability to gain unauthorized access.
Given the nature of the issue, organizations should prioritize patching immediately. Exploitation is plausible, and the potential impact on confidentiality and integrity is significant.
Current intelligence indicates no known public exploits or proof of concepts available, but this does not mitigate the urgency for remediation.
Vulnerability Details
The vulnerability identified in HPE Integrated Lights-Out firmware versions 5 and 6 could be exploited remotely, allowing attackers to bypass authentication mechanisms. The CVSS score from the NVD indicates a critical level of risk, with a base score of 9.8 and a severity classification of critical. This reflects substantial potential impacts across confidentiality, integrity, and availability.
Affected versions include integrated_lights-out_5_firmware with versions ranging from 2.63 to 3.00 and integrated_lights-out_6_firmware from 1.05 to 1.55. The official disclosure date was December 19, 2023.
Technical Analysis
The root cause of this vulnerability stems from inadequate authentication checks in the affected firmware, which enables attackers to initiate unauthorized sessions. The attack vector is network-based, with a high complexity requirement, meaning that while exploitation is feasible, it may require a sophisticated approach.
Exploitation does not require any user interaction and can occur without prior privileges, leading to potential unauthorized access. The impacts on confidentiality are low, but integrity could be significantly compromised, as attackers may alter configurations or settings.
Risk & Impact Analysis
Risk to organizations includes significant potential for unauthorized access and manipulation of critical infrastructure. The blast radius could affect multiple components relying on the compromised firmware, escalating the impact across the organization.
Given the high CVSS score and exploitability assessment, organizations should address this vulnerability in their priority patch cycle. The potential for exploitation can lead to severe consequences, including data breaches and operational disruptions.
The current EPSS score indicates a lower percentile for risk of exploitation; however, organizations should not become complacent. The urgency for remediation remains high.
