CVE-2022-44611 is classified as a medium-severity vulnerability affecting the BIOS firmware of certain Intel processors, including models in the Celeron, Pentium, and Atom families. This vulnerability allows improper input validation, which may enable a privileged user to escalate privileges through adjacent access. The CVSS score assigned to this vulnerability is 6.9, indicating a moderate risk to affected systems.
The potential impact of this vulnerability is significant. Attackers may leverage this flaw to gain elevated privileges, which could lead to unauthorized access to sensitive information or system control. Given the nature of adjacent network access, organizations must assess their exposure and implement timely remediation strategies.
Intel has modified the status of this vulnerability, and organizations should take immediate action to patch affected systems. The urgency for defenders is high, as the implications of exploitation can be severe.
Intel released advisory details on this vulnerability on August 11, 2023. Security teams should review the advisory for guidance on mitigation and ensure all relevant firmware updates are applied.
Vulnerability Details
The official description of CVE-2022-44611 highlights improper input validation in the BIOS firmware for some Intel processors, allowing a potential escalation of privilege via adjacent access. The vulnerability has a CVSS score of 6.9, categorized as medium severity. The affected products include a range of Intel processors, specifically the Celeron J6413, Celeron N6211, Pentium J6425, and Atom series, among others.
The publication date for this vulnerability was August 11, 2023, and it is categorized under CWE-20, which pertains to improper input validation.
Technical Analysis
The root cause of this vulnerability lies in the BIOS firmware's handling of input validation. The attack vector is classified as adjacent network, meaning that an attacker must have physical or logical access to the network segment where the vulnerable system resides. The attack complexity is high, requiring specific conditions to be met for exploitation.
Privileged access is not required initially, and no user interaction is necessary for exploitation. The potential impact includes high integrity impact due to the ability to escalate privileges, while confidentiality impact is rated as none, and availability impact is low.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and the ability to control systems that are critical for operations. The blast radius can encompass any system that utilizes the affected Intel processors, making it essential for organizations to address this vulnerability promptly.
Given the CVSS score of 6.9 and the lack of confirmed public exploits, organizations should treat this vulnerability with high urgency, ensuring it is included in the priority patch cycle.
