CVE-2025-21533 is a medium-severity vulnerability affecting Oracle VM VirtualBox, specifically in the core component of the product. This vulnerability allows low privileged attackers with logon access to the infrastructure where Oracle VM VirtualBox runs to compromise the system. Successful exploitation may lead to unauthorized access to critical data, posing significant risks to organizations.
The CVSS 3.1 base score for this vulnerability is 5.5, indicating a medium-impact level. Given its exploitability, organizations should assess their infrastructure for affected versions and prioritize patching to mitigate risks associated with possible data breaches.
Organizations using Oracle VM VirtualBox versions prior to 7.0.24 and prior to 7.1.6 are particularly vulnerable. Patching these versions is crucial to preventing potential attacks that could compromise data integrity and confidentiality.
Organizations should prioritize patching immediately. The successful exploitation of this vulnerability can result in serious data exposure and unauthorized access.
Vulnerability Details
The vulnerability in the Oracle VM VirtualBox product has been described as easily exploitable, enabling attackers to gain critical access without elevated privileges. The CVSS vector is defined as CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, indicating that the attack vector is local, with low complexity, and requires low privileges, but does not require user interaction.
The vulnerability was published on January 21, 2025, and has been classified under CWE-863, which pertains to vulnerabilities related to unauthorized access.
Technical Analysis
The root cause of this vulnerability lies in the configuration and security management of Oracle VM VirtualBox, which allows a low privileged user to exploit the system. The attack vector is local, meaning the attacker must have access to the physical or virtual infrastructure hosting Oracle VM VirtualBox.
The attack complexity is low, and it requires low privileges, making it relatively easy for attackers to launch an exploit without needing user interaction. The potential impact is high on confidentiality, meaning sensitive data could be accessed or exfiltrated.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-21533 is significant, especially for organizations that rely on Oracle VM VirtualBox for virtualization. The ease of exploitation combined with the potential for unauthorized access to sensitive data presents a serious threat landscape.
Organizations should evaluate the potential blast radius of this vulnerability, as successful attacks could lead to widespread data exposure across virtual machines and applications hosted on compromised systems.
Based on the CVSS base score of 5.5 and the lack of known exploits, organizations should address this vulnerability in their priority patch cycle. Regular assessment of impacted systems is advised to ensure that vulnerabilities do not go unaddressed.
