Vulnerability Details
The vulnerability identified as CVE-2022-28638 is characterized by local information disclosure and the potential for arbitrary code execution. It has been rated with a CVSS 3.1 score of 7.8, indicating its high severity. The affected product is HPE Integrated Lights-Out 5 (iLO 5) firmware Version: 2.71. This vulnerability falls under the CWE-200 classification, which pertains to information exposure. The discovery was publicly reported on September 20, 2022, and the vendor has since released updated firmware to rectify these security flaws.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user inputs within the iLO 5 firmware, allowing attackers with local access to exploit the flaw. The attack vector is classified as local, meaning that the attacker needs physical or local access to the system to exploit the vulnerability. The attack complexity is low, and it requires only low privileges to perform the attack, with no user interaction required.
The impacts of this vulnerability are significant, as it can lead to high confidentiality, integrity, and availability impacts. If exploited, attackers may gain unauthorized access to sensitive information or disrupt the normal functioning of the affected devices.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-28638 is significant, particularly for organizations that utilize HPE Integrated Lights-Out 5 for server management. Successful exploitation could lead to unauthorized access to sensitive information stored on affected systems, potentially resulting in data breaches or service disruptions. The blast radius is considerable as many systems may rely on the iLO for critical management tasks.
Organizations should be aware that the CVSS score indicates a high risk level, and thus urgency for remediation is critical. The EPSS score of 0.0013 suggests a low probability of exploitation, but the potential impact remains high due to the nature of the vulnerability.
