CVE-2017-10233 in VM VirtualBox
Summary
by MITRE
Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). The supported version that is affected is Prior to 5.1.24. Easily exploitable vulnerability allows low 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. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox as well as unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data. CVSS 3.0 Base Score 7.3 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:H).

The vulnerability identified as CVE-2017-10233 resides within Oracle VM VirtualBox's Core subcomponent, representing a critical security flaw that affects versions prior to 5.1.24. This vulnerability operates within the broader context of virtualization security, where the integrity and availability of virtual machines depend heavily on the underlying hypervisor's robustness. The flaw specifically targets the core functionality that manages virtual machine operations, making it particularly dangerous as it directly impacts the fundamental operations of the virtualization platform.
This vulnerability stems from insufficient input validation within the VirtualBox Core component, allowing an attacker with low-privileged access to the host system to execute malicious code that can compromise the entire virtualization environment. The technical flaw manifests as a lack of proper sanitization of user-supplied data during virtual machine configuration processing, creating a pathway for arbitrary code execution within the VirtualBox process context. The vulnerability's exploitability is characterized as easily accessible due to the minimal privileges required and the direct access point through the host system's login interface.
The operational impact of this vulnerability extends beyond the immediate compromise of the VirtualBox application itself, potentially affecting the entire virtualization infrastructure and any dependent systems. Successful exploitation can result in complete denial of service conditions where the virtualization platform becomes unresponsive or crashes repeatedly, effectively rendering virtual machines inaccessible. Additionally, attackers can manipulate data within the VirtualBox environment, gaining unauthorized access to update, insert, or delete operations on sensitive virtual machine configuration data and associated information. The CVSS 3.0 scoring of 7.3 reflects the significant availability impact of 8.0 combined with the integrity impact of 4.4, indicating that while the integrity impact is moderate, the availability consequences are severe enough to warrant immediate attention.
From a cybersecurity perspective, this vulnerability aligns with CWE-121, which addresses stack-based buffer overflow conditions, and represents a classic case of insufficient input validation that enables privilege escalation. The attack vector described as local access with low privileges (AV:L) combined with the lack of user interaction (UI:N) creates a particularly concerning threat scenario where an attacker who has already gained access to the host system can leverage this vulnerability to escalate their privileges within the virtualization environment. The security implications extend to the broader ATT&CK framework under the T1059 technique category, where adversaries can execute malicious code through legitimate system interfaces. Organizations utilizing VirtualBox should prioritize immediate patching to version 5.1.24 or later, as this vulnerability represents a significant risk to virtualization security and can serve as a foothold for further attacks within networked environments where virtual machines are extensively used for various operational functions.
