CVE-2017-3558 in VM VirtualBox
Summary
by MITRE
Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). Supported versions that are affected are Prior to 5.0.38 and Prior to 5.1.20. Easily "exploitable" vulnerability allows unauthenticated 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 and unauthorized read access to a subset of Oracle VM VirtualBox accessible data. CVSS 3.0 Base Score 8.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:H).

The vulnerability identified as CVE-2017-3558 resides within Oracle VM VirtualBox's Core component, representing a critical security flaw that affects versions prior to 5.0.38 and 5.1.20. This vulnerability operates at the foundational level of virtualization infrastructure, making it particularly dangerous as it can be exploited by attackers who have already gained access to the underlying physical infrastructure where VirtualBox operates. The attack vector requires only local access to the system, eliminating the need for complex network-based exploitation techniques. The CVSS 3.0 scoring of 8.5 reflects the severity of impact across confidentiality, integrity, and availability domains, with the vector AV:L/AC:L/PR:N/UI:N/S:C indicating that an attacker with local privileges can exploit this vulnerability with low complexity and no additional privileges. This vulnerability is classified under CWE-119 in the Common Weakness Enumeration catalog, which deals with insufficient protection of memory buffers, indicating potential memory corruption issues within the virtualization core.
The technical flaw manifests as a memory management issue within VirtualBox's core processing mechanisms that can be triggered by malformed input or specific sequence of operations within the virtualization environment. When exploited, this vulnerability allows attackers to cause complete denial of service conditions through system hangs or repeated crashes, effectively rendering the virtualization platform unusable. The exploitation process involves leveraging the local access to manipulate internal VirtualBox processes, potentially leading to privilege escalation within the virtual environment. The vulnerability's impact extends beyond the immediate VirtualBox instance, as successful exploitation can compromise other Oracle products that may be running within or interacting with the compromised virtual environment, creating a cascading effect that can undermine broader enterprise security postures.
The operational impact of this vulnerability is substantial, as it provides attackers with unauthorized capabilities to modify system data and potentially gain access to sensitive information stored within the virtualized environment. The ability to perform unauthorized updates, inserts, and deletions of data within VirtualBox's accessible components can lead to data corruption or manipulation that may affect virtual machine configurations, guest operating system integrity, and overall system stability. Additionally, the unauthorized read access to subset of VirtualBox accessible data creates potential for information disclosure attacks that could expose sensitive configuration details, user credentials, or system parameters. The complete denial of service capability represents a particularly concerning aspect as it can render virtualization infrastructure unavailable for legitimate business operations, potentially causing significant downtime and operational disruption.
Mitigation strategies for CVE-2017-3558 should prioritize immediate patching of affected VirtualBox installations to versions 5.0.38 or 5.1.20 and later, which contain the necessary security fixes. System administrators should implement strict access controls to limit local access to VirtualBox installations and consider network segmentation to reduce the attack surface. Monitoring and logging should be enhanced to detect unusual patterns of system behavior that may indicate exploitation attempts, including repeated crashes or unexpected system hangs. The vulnerability's classification under the ATT&CK framework would fall under T1068 for locally executed commands and potentially T1499 for system disruption, making it important for security teams to monitor for these specific threat patterns. Regular vulnerability assessments should include checking for outdated VirtualBox installations, and organizations should consider implementing automated patch management solutions to ensure timely remediation of similar vulnerabilities in the future.
