CVE-2023-22100 in VM VirtualBox
Summary
by MITRE • 10/25/2023
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 7.0.12. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox. Note: Only applicable to 7.0.x platform. CVSS 3.1 Base Score 7.9 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H).

CVE-2023-22100 represents a critical vulnerability within Oracle VM VirtualBox's core component that affects versions prior to 7.0.12. This vulnerability operates under the Common Weakness Enumeration framework as CWE-20, specifically addressing improper input validation within the virtualization environment. The flaw exists in the infrastructure where Oracle VM VirtualBox executes, making it particularly dangerous as it requires only high-privileged access to the underlying system to exploit. The vulnerability's classification as easily exploitable indicates that attackers with legitimate administrative credentials can leverage this weakness to compromise the virtualization platform. The CVSS 3.1 score of 7.9 reflects the severe impact across confidentiality and availability domains, with a vector indicating local access with low attack complexity and high privileges required. This vulnerability demonstrates the dangerous intersection of privilege escalation and virtual machine security where an attacker with access to the host system can potentially gain unauthorized access to all data within the virtualized environment.
The technical implementation of this vulnerability stems from insufficient validation mechanisms within Oracle VM VirtualBox's core processing functions, creating a pathway for malicious actors to manipulate the virtualization layer. Attackers with logon privileges to the host infrastructure can exploit this weakness to achieve complete compromise of the virtualization environment, potentially leading to unauthorized data access or complete denial of service conditions. The scope change aspect of this vulnerability indicates that impacts may extend beyond the immediate Oracle VM VirtualBox installation to affect other connected systems or applications that depend on the virtualization platform's integrity. This characteristic aligns with the ATT&CK framework's privilege escalation techniques, where initial access to a system provides the foundation for deeper exploitation within the virtualized environment. The vulnerability's impact on availability is particularly severe, as successful exploitation can cause repeated crashes or complete system hangs that disrupt virtual machine operations and potentially affect business continuity.
Organizations running affected versions of Oracle VM VirtualBox face significant operational risks from this vulnerability, as it provides a direct pathway for attackers to compromise their virtualized infrastructure. The high privilege requirement for exploitation does not diminish the severity, as administrative access to host systems is often achievable through various attack vectors including credential theft, phishing, or lateral movement within networks. The potential for complete data compromise means that sensitive information stored within virtual machines could be accessed without detection, while the denial of service capability could disrupt critical business operations. The vulnerability's presence in the 7.0.x platform series indicates that organizations must urgently evaluate their virtualization environments and implement immediate patches to prevent exploitation. Security teams should consider this vulnerability as a high-priority threat requiring immediate attention, particularly in environments where virtualization is extensively used for business-critical applications and data processing. The impact extends beyond simple data security to include operational resilience and system availability, making comprehensive remediation essential for maintaining secure virtualized environments.
